Afinia H-Series 3D Printer User’s Manual
Overview
The Afinia H-Series 3D Printer primarily consists of the Extruder, Print Platform, Material Spool,
and Filament, all supported by the Pedestal. The Printer is initialized with a single switch, and
calibrating the position of the print platform is done using the included Afinia software.
The Afinia software sends the print data from a Mac or PC to the Printer over a single USB cable.
The Print Platform moves both vertically and front-to-back while the Extruder moves left-to-right,
providing the necessary 3 axes of operation (see Figure 2). The Extruder delivers the Filament
from the Material Spool into the Nozzle, which heats the filament to printing temperature and
deposits it on the Platform.

Getting Ready to Print
Preparing the Platform
Before you start printing, the platform must be prepared so that the model adheres to the platform
enough to be printed without the model moving. At the same time, you will want the model to be
easy to remove from the platform after printing. There are several options for preparing the
platform:
FR-4 Board (Glass-reinforced Epoxy Laminate)
Many users have reported excellent results by using a piece of FR-4 Board to cover the build
platform. FR-4 Board is a perforated, glass-reinforced epoxy laminate sheet.
When using FR-4 Board, the first layer of the raft pushes
plastic into all the perforations, and this provides a strong
mechanical bond with the surface that prevents it from
later lifting. The FR-4 Board can be either taped down
(with masking tape or double-sided tape), or clipped to
the platform as shown in the picture to the right. Make
sure the clips are on the front and back of the platform
only to avoid interfering with the platform movement!
It can be easier to remove the model from the FR-4
Board after the model has cooled down. As the plastic
cools, it shrinks away from the perforations, which make
it easier to pull out.
Some FR-4 Boards may work better than others. For consistent printing, it is recommended that
you use the FR-4 Board included with the Printer.
Blue Masking Tape
Many
users
have
reported
successfully using Blue Masking Tape
as a platform surface. Simply cover
the platform with a layer of blue
masking tape with as little overlap as
possible and print onto the tape.
Replace the tape when it wears out.
Whichever
platform
preparation
method you use, the two factors that
most reduce the risk of warping on
large prints are ensuring that the
platform is well leveled and well
pre-heated.

Afinia H-Series 3D Printer User’s Manual
Starting the Afinia H-Series 3D Program
If the application is not already open, click the Afinia H-Series 3D icon on the desktop (Windows)
or in the Applications folder (Mac). The program should open and appear as shown below:
Windows version
Mac version
Initializing the Printer
Before anything can be printed, the printer must be initialized. Click the Initialize option from the
3D Print menu. The printer will beep and the initialization procedure will begin. The printer will
then return the platform and print head to the printer’s origin and beep again when it is ready.
Windows version
Mac version
The front Initialization Switch can also be used for initialization. Hold down the Initialization
Switch for one second to trigger the initialization procedure.
TIP: If your printer is not responding properly, the first thing to try is to re-initialize the printer by
clicking the Initialize option from the 3D Print menu.

Afinia H-Series 3D Printer User’s Manual
Leveling the Print Platform
Before calibrating the nozzle height, always check the vertical nozzle distance from each corner
and center of the print platform. Open the Maintenance dialog box from the 3D Print menu.
If you already know the nozzle height, enter that height minus 1.8mm in the To: box, then click the
To: button. If your nozzle height is 135.3, for example, enter 133.5.
If you do not yet know the nozzle height, Click the To: button to bring the platform to the displayed
height, then slowly increment the height until the platform is about 2 mm from the nozzle, clicking
To: after each increase.
Use the five position buttons to check that the platform at all four corners and the center are the
same distance from the nozzle.
If the platform is not the same distance from the
nozzle at all five points, you will need to adjust the
platform until it is level. There are 3 screws under
the platform that are used to level the platform.
Leveling screws
Loosening a screw will raise the related corner of
the platform, while tightening the screw will lower
the same part of the platform. Adjust the screws as
needed until all four corners and center of platform
are the same vertical distance from the nozzle.
Always recalibrate the nozzle height after leveling the platform.
Calibrating the Nozzle Height
This section is probably the most important of the entire manual. Please read it carefully to
ensure that you understand the nozzle height setup procedure, as it is vital to successful 3D
printing.
To print successfully, the platform should be set to start at a distance of 0.2mm from the nozzle.
As each printer is slightly different, this distance needs to be calibrated before starting to print.
To determine the correct nozzle distance, please follow these steps:
1. Open the Maintenance dialog box from the 3D Print menu and click the Center button.
The current nozzle height is indicated as shown in the Maintenance dialog images above.
In the Windows example, the platform is currently at the bottom of the printer; the Mac
example has the platform 135.5mm from the bottom.
2. Enter the height to which you want the platform to move to into the textbox and click the To
button. In the above Windows example, the platform will move to 121 mm above the
platform’s origin. In the Mac example, the platform is already at the height selected.
3. Check the distance between the nozzle and the platform. If the platform is currently at
121mm and appears to be about 12mm away from the nozzle, change the number in the
text box to by 9mm to 130 and click the To button. Use small increments from there when
calibrating the nozzle to avoid striking the platform into the nozzle.
13
Afinia H-Series 3D Printer User’s Manual
4. Once you are about 1mm away from the nozzle, increase the number in the text box by
0.1mm increments and click the To button. Repeat until you get 0.2mm from the nozzle.
TIP: An easy way to check the
distance between the nozzle
and platform is to fold a piece of
paper in two, which will be
about 0.2mm thick. Use this
as a spacer to gauge the
distance between the nozzle
and platform.
5. Once you have the platform within
0.2mm of the nozzle, click the Set
Nozzle Height button to save the
current nozzle height.
6. Check the nozzle height at all four corners of the platform. Repeat the Platform Leveling
and Nozzle Height Calibration processes if needed.
You may need to recalibrate the nozzle height after moving the printer or changing the
printing platform if you find the models are not adhering to the platform properly or are
warping.
TIP: If you crash the platform into the nozzle while making height adjustments, it is good practice
to re-initialize the printer and before undertaking any other operations.
Other Maintenance Options
Extrude
Squeezes material out of the nozzle. Click this button, and the nozzle is heated. When the
temperature is high enough (260° C), the material is squeezed out of the nozzle. The system
beeps before material starts extruding, and it beeps again when finished. When changing the
material (see page 27), use this function to load the new material to the nozzle. It can also be used
to test whether the nozzle is working correctly.
Withdraw
When the material runs out, or the nozzle needs to be changed, click this button. Once the
nozzle is up to temperature (260°C) and the printer beeps, gently pull out the material.
New Spool
The New Spool button is used so the software can keep track of how much material has been
used, and warn you if you don’t have enough material left to print your model.
Click the button and enter the value of how many grams of material you have on the current spool.
If it is a new spool, the quantity should be set to 700 grams. You can also specify whether the
material you are printing with is ABS or PLA.
Windows version
14
Mac version
Afinia H-Series 3D Printer User’s Manual
TIP: An empty spool weighs about 280 grams. If you are installing a partially used spool, weigh it,
and subtract 280 grams from the weight. Enter that value into the material Weight text box.
Status
This area displays the current temperature of the nozzle and platform and if either element is
currently being heated.
Nozzle & Platform Position Controls
The five buttons (FL, FR, Center, NL, NR) control the position of the nozzle and the platform.
The nozzle moves to the left and right; the platform moves forward and backward.
The To button controls the height of the platform, and is used in the nozzle height calibration
procedure described on page 13.
The Bottom button returns the platform to the lowest position.
Set Nozzle Height
Takes whatever value you have in the To box and saves it as the Nozzle height to use during
printing.
Stop All
Stops heating and all the movement of the printer. Once you click this button, the current model
being printed is cancelled. You CANNOT resume a print job once the printer has been stopped.
After you use the Stop All function, you will need to re-initialize the printer.
Pause Print
This button allows you to pause a print in mid-progress while allowing you to resume the print job
where it left off. This is very useful if, for example, you want to change the material color mid-print.
Another use for pausing a job mid-print is to allow fasteners to be inserted into printed cavities and
then printed over to lock the fastener into place.
This option is only available when the printer is actively printing.
Table Heat 1 hr
Click the Table Heat 1 hr button to heat the table to 105º C for a full hour.
Stop Preheat (Windows) / Stop Heat (Mac)
This button will halt any heating of the table, either the 1 hour heat or the 15 minute preheat from
the 3D Print menu. This option only appears when the table in actively being heated by one of
these two operations.

Print Setup Options
Click the Setup option in the 3D Print menu. The following dialog box pops up:
Mac version
Print Settings
Windows version
Z Resolution
This setting specifies the print resolution or layer thickness of the printer. Options are 0.2mm to
0.4mm per layer, in 0.05mm increments.
Base Height
This sets the thickness of the Support Raft before the support layer is printed under the part.
The printer starts with a raft of non-solid material in
which all the lines of support material are printed
along the Y-axis. Layers of support material are built
up for as many millimeters as you have specified. It
is on this Support Raft that the first layers of dense
support are printed along the X-axis; the model itself
is printed on top of the dense support material.
The default value for this setting is 2mm.
Part Settings
Angle
The Part Angle determines at what point solid (dense) support material gets used. If the angle is
smaller than the selected setting, the printer will add solid fill layers under the part surface. The
thickness of this solid (dense) support is determined by the “dense” parameter under the Support
options as described below.
Surface
This setting determines how many layers form the bottom face of a part when it is not solid. For
example, if you set it to 3, the machine will print 3 complete layers before going into non-solid
mode.
This does not affect the side wall thickness on non-solid parts, which are all the same thickness
(approximately 1.5mm) regardless of the fill mode.

Fill Settings
There are four ways to fill the interior of the parts, as described below.
The part is nearly solid plastic, giving you the
strongest structure.
This Fill setting is
recommended for functional engineering
parts.
The interior of the part is filled with a
reasonably small scaffold structure. This is
the default Fill setting.
Mac setting: Solid
Mac setting: Loose
Mac setting: Big Hole
Mac setting: Hollow
The interior of the part is filled with a medium
spaced scaffold structure.
The interior of the part is filled with a large
spaced scaffold structure, using the least
amount of material.
Support Settings
Dense
This represents how many layers of dense support material is
printed directly beneath the model. The greater the number
of dense support layers, the more stable the print will be but
the support will be more difficult to remove.
Angle
The Support Angle setting specifies the Angle at which support material gets used. For example,
if 10° is selected, support material only gets used if angle of surface is less than 10° from
horizontal (so support material is almost not used unless there is a direct overhang). If set to 50°,
support material is used for any surface that is less than 50° away from horizontal.
Angle set to > 10º
Angle set to > 50º

Afinia H-Series 3D Printer User’s Manual
There is a balance between minimizing the amount of support
material and maintaining the quality of the part, as well as
minimizing the difficulty of removing support material.
The orientation of the part on the print platform is critical in
determining both how much support material gets used and how
difficult the support material will be to remove.
As a general rule, it is easier to remove support material from the
outside of a part than from the inside. As can be seen in the
picture to the right, the part would use a lot more support material
if printed with the opening facing downwards than if it were facing
upwards.
Space
This setting specifies the distance between the lines of non-solid support material. Changing this
parameter changes the balance between the quantity of support material used, ease of support
material removal, and part print quality. Only advanced users should change the Space setting.
Area
This setting specifies the surface area above which support
material gets used. When you choose 5mm2, for example,
there will be no support if the overhanging area is less than
5mm2. While a little material is saved and a slightly faster
print speed is achieved when this setting is increased, the
stability of the part may be reduced during printing.
Other Settings
Stable Support
Stable support creates support that is more solid, and the model is less likely to distort, but the
support material will be more difficult to remove.
TIP: All setup and configuration settings aside from the Nozzle Height Calibration are stored in
the software, not on the Afinia H-Series 3D Printer. If you move the printer to a different
computer, you will need to repeat all the calibration and setup procedures.
22
Afinia H-Series 3D Printer User’s Manual
Printing
TIP: One of the keys to successful printing on the Afinia H-Series 3D Printer is platform
preparation and preheating. Particularly with large parts, there is a tendency for the edges of
the part to lift from the platform (which can be a little colder than the center) and cause the
parts to warp. The best results will be achieved if:
•
•
•
•
The platform is perfectly level
The nozzle height is correctly set
The printer is being run in a room that is not too cold (warmer than 65° F) and free of drafts
The platform is very well preheated
Please ensure the following points are taken care of before printing:
Connect the 3D printer, initialize it, and set up the printing system. Load the model and place it
properly on the virtual platform of the software window. Check if there is enough material for the
model (the software will, generally, tell you if there is not enough material when you begin the print).
If not, change the reel to a new one.
For models over 40mm2 in surface area, it is recommended that you preheat the build platform.
Click the Table Preheat 15 mins option in the 3D Print menu to preheat the platform. Let the
platform heat to at least 100° C before beginning to print.
Click Print from the 3D Print menu.
Print Options
Nozzle Height
You can make changes to the Nozzle Height using this setting, but it is not recommended unless
you know that the value you are entering in is correct.
If the nozzle is too far from the platform during printing, the material may not adhere correctly to
either the platform or to the previous layer.
If the nozzle height is set too high, the platform can raise up into contact with the nozzle itself,
potentially damaging the nozzle.
It is recommended that you use the Calibrate Nozzle Height process as listed on page 13 to
make any changes rather than in the Print dialog.
Quality
Options are Normal, Fast, or Fine. This setting determines the speed at which the printer moves.
As a general rule, the slower you print the better the quality of the parts, although there are
exceptions to this rule.
For tall parts, running at Fast speed can be problematic as the printer can vibrate to the extent that
print quality is affected.
23
Afinia H-Series 3D Printer User’s Manual
For large surface area parts, the Fine setting can be problematic as the part takes longer to print
and the corners of the raft are more likely to lift from the platform.
UnSolid Model
This function is useful for printing STL files that are not perfect. A perfect STL file is a fully
enclosed surface, with no holes in the surface skin, and no overlapping surfaces. If your file is
not perfect, this option should allow you to print it anyway.
No Raft
While you can choose to skip the Raft with this option, it is not recommended. The raft adds
stability to the adhesion between the part as it is printing and the platform.
Heat Platform after finish
Checking this option will keep the platform temperature at a higher level after printing is complete.
This can make it easier to remove the model from the platform, depending on the platform
preparation.
TIP: Once the print has started, you can unplug the PC from the printer. The print job is stored in
the printer’s internal memory, so the PC is no longer required
Calculating model costs
The easiest way to calculate the cost of the material that will be used for your model is to use the
Print Preview option under the 3D Print menu. The application will calculate the total weight of
material used, including the raft and any support material.
Use the weight from the Print Preview to determine the cost to print the model using the following
formula:
Cost of Spool
Cost to Print = Weight of Model X
Full Filament Weight
(
)
Use the full weight of the filament that you purchased, not the current weight of the spool. For
instance, if you purchased a 700g spool of ABS filament, you would divide the cost of the spool by
700g to get the cost per gram of material.
The main factors that affect model cost are the Fill and Support settings. For example, you are
printing a cube measuring 30mm x 30mm x 30mm with a layer thickness of 0.2mm. With the
Support settings left at their default values, the following quantities of material will be used for each
of the four Fill settings:
PC Fill Setting
Mac Fill Setting
Weight of Model
17.2 g
12.0 g
9.4 g
8.5 g
In this instance, the model printed at the lowest density Fill setting will be about half the cost as
printing it at the highest density Fill setting, but that ratio does not apply to all models. Each
model will have a different relationship between the amount of material used and the Fill and
Support settings. Always run a Print Preview if you are calculating the printing costs of any given
model.

Afinia H-Series 3D Printer User’s Manual
Model Removal
When the model has finished printing, the printer will beep, and the nozzle and platform stop
heating.
It is very strongly recommended that you do not attempt to remove the finished model from the
platform while in the printer. If you do, you may bend the entire platform assembly so that it is no
longer perpendicular to the printer head.
Remove the printer platform from the printer by removing the 2 screws at the bottom of the
platform.
If you are using the FR-4 Board platform method, simply
remove the clips holding the board to the platform and
place the board with the model still attached on a flat
surface.
Gently slide a spatula or chisel under the model and
slowly wiggle it back and forth to lift the support
material from the platform.
Remember to use gloves as the platform and model
may still be hot and to prevent injury from any tool
being used to help release the model from the FR-4
Board.
TIP: Depending on the platform preparation method you are using,
the model may be easier to remove from the printer when it is still
hot. If you want to heat the platform before removing your model,
use the Table Heat option from the 3D Print menu.
CAUTION: It is strongly recommended that you do not attempt to remove the
model from the platform while the platform is still attached to the printer. Doing
so may damage the printer or affect the platform level and nozzle height
calibration.
CAUTION: It is recommended that gloves be worn as the platform may still be hot
and to prevent injury from any tool being used to help remove the model from the
platform.
25
Afinia H-Series 3D Printer User’s Manual
Removing Support Material
Printed models are composed of two parts. One part is the model itself, and the other part is the
support material used to support any overhanging parts of the model.
The support material is the same physical material as the model material, but printed at a much
lower density. Support material is very easy to distinguish from the model material, making it is
easier to remove.
The left picture above shows the teapot with its support material still attached, while the right
picture shows the teapot with support material removed.
The support material can be removed using a combination of tools. Some material can easily be
removed by hand. Support material close to the model is easier to remove using tools such as
wood carving chisels, long nose pliers, or wire cutters.
CAUTION: ALWAYS WEAR SAFETY GLASSES WHEN
REMOVING THE SUPPORT MATERIAL!
CAUTION: The support material and the tools are sharp. Wear gloves and safety
glasses when removing the part from the printer.
26
Afinia H-Series 3D Printer User’s Manual
Maintenance
Changing the Material
First withdraw the leftover material from the printer.
Initialize the printer and choose
Maintenance from the 3D Print menu. Click the Withdraw button and the nozzle will start to
heat. When the nozzle reaches the correct temperature, the printer will beep and you can gently
withdraw the material.
Once the old filament has been removed, place a new spool of material on the spool holder, and
pull it through the filament tube, until the material is about 10cm out of the tube, then insert it into
the hole at the top of the extruder head.
Click the Extrude button. After the printer nozzle has warmed up to 260° C, the printer will beep.
Gently push the filament into the hole at the top of the extruder head with a little downward
pressure until the extruder mechanism starts to feed the filament through on its own.
After the new filament has been loaded, use the
New Spool function to help the printer keep track
of the amount of filament is now available.
TIP: If you are loading a different color filament
than the last spool, run the Extrude function
a few times once the new spool is in place
but before printing your next model. This
will help extrude out any remaining filament
material of the previous color.
If the nozzle is blocked, remove the nozzle and clean it.
The extruder and platform are hot. Use gloves when working in this area
of printer.
Vertical Calibration
The Vertical calibration procedure allows you to ensure that the printer
platform is perfectly horizontal and that the printer prints consistently in
the X, Y, and Z directions.
First, print the supplied Calibration model on your printer at the scale of
the part when initially opened. The calibration file is in C:\Program
Files\Afinia\Example.
After the calibration model is printed, remove the platform without
removing the parts.
27
Afinia H-Series 3D Printer User’s Manual
Open the Calibrate dialog from the 3D Print menu.
Measure the X1 and X2 length, as shown in the pictures
below.
IMPORTANT NOTE: Before you enter any new
calibration values, always click the Reset button,
otherwise the new values get added to the old ones.
Before you enter any new values, the bar at the very top
of the screen should read: XY: 0.00 deg / XZ: 0.00 deg.
Measure the calibration print from front left to rear right corners of the
printed parts on the platform to determine the X1 measurement, and
the rear left to front right to determine the X2 measurement.
Be sure that you are not including the raft or support material when
taking these measurements!
Enter the measured X1 and X2 values into the appropriate boxes.
Checking the X1 Measurement
Next, carefully remove the Front Center ‘L’ shaped component
from the platform and check the inside angle. If it is not 90º,
measure the exact distance in millimeters that the end of the
long arm of the part would need to move to get the angle to be
90º and enter that distance into the Z box. If the angle is less
than 90º, the value to be put into the Z box will be a positive
value. If the angle is more than 90º, the value to put into the Z
box will be a negative value. For example, if the end of the
long arm is 1.3 mm above the surface, enter -1.3 in the Z box.
Finally, measure the long arm of the Front Center component from the
inside of the angle to the end, which should be 40mm at full scale. Enter
the exact measured value into the H box of the Calibrate dialog box.
Click OK to record all these values and exit the calibration window.
Cleaning the nozzle
After a lot of printing, the nozzle may be covered with a layer of oxidized ABS. When the printer
is printing, this oxidized ABS may melt on the nozzle, and may create discolored spots the model.
To avoid this you need to regularly clean the nozzle.
Preheat the nozzle as the first step in order to melt the oxidized ABS. Use the Extrude button on
the Maintenance dialog box, and then click the To Bottom button. Wait until the material is
finished extruding, then remove the extruded filament.
Use a heat-resistant material such as 100 percent cotton cloth or soft paper and a pair of pliers.
With the material between the pliers and the nozzle, apply gentle pressure with the pliers and turn
the pliers to remove the oxidized filament material. Do not apply heavy pressure!
28
Afinia H-Series 3D Printer User’s Manual
Remember, the nozzle heats up to 260° C (500° F), or over two and a half the boiling point of water.
Do not touch the nozzle or nozzle mount with bare skin during this process!
TIP: Removing and soaking the nozzle in acetone will help remove excess material from the
nozzle. Ultrasonic cleaning baths will also work.
Removing / Changing the Nozzle
If the nozzle becomes blocked, you may need to
remove it in order to unblock or change it altogether.
To remove the nozzle, use the nozzle wrench
provided in the toolkit that comes with your Afinia
H-Series 3D Printer.
TIP: Heating the nozzle will generally make it
easier to remove. Be careful when handling
the heated nozzle once it has been removed!
Cleaning the Platform
Regardless of the method of preparing the platform that you have chosen, a smooth surface will
improve your results.
•
•
If you are using the FR-4 Board as the print surface, you should remove any remaining
filament material from the surface of the board before printing again.
If you are using blue painter’s tape on the platform, you will need to replace the tape once
it becomes uneven. You may need to remove excess adhesive from the platform during
the process of replacing the tape.
Lubrication of bearings
The 3 axial bearings on the Afinia H-Series 3D Printer may occasionally require a bit of lubrication
to keep it operating smoothly. The recommended grease to use is lithium grease.
When lubricating the bearings, first clean off as much old grease as possible from the bearings
before applying new grease to the bearing. Slide the platform several times in the appropriate
direction to spread the grease evenly.
Spare parts
Most of the plastic parts on the printer can be printed by the Afinia H-Series 3D Printer itself. If
you need spare parts for your printer, the files for the printable parts can be found in the
C:\Program Files (x86)\Afinia\Example\Spare Part folder.

Afinia H-Series 3D Printer User’s Manual
Tips & Tricks
Preheat the platform before printing
Large parts can sometimes have their corners lift from the platform, which causes the part to
distort. This is caused by uneven heat across the surface of the platform. Preheating the
platform before beginning large parts is essential to minimize this lifting.
Position the parts as close to the center of the platform as possible
The center of the platform is where the heating is most regulated, which helps to keep the support
raft adhered to the platform. Try to avoid printing any object near the edges of the platform.
Decrease print time where possible
The faster you can print parts, the less lifting from the platform you are likely to get. Some ways
to increase print quality include:
•
•
•
•
If possible, try to avoid printing large parts in solid mode
Set the layer resolution to as large a value as possible while still retaining the quality
needed for the finished part
Print the part in Normal or Fast mode
If printing multiple parts at once, reduce the number of parts that are being printed
Regularly check the nozzle height calibration
The nozzle height can change for a number of reasons, such as changing the position of the
printer, adding a new layer of surface preparation to the platform, or removing and replacing the
FR-4 Board. To check or change the nozzle height, please see Calibrating the Nozzle Height
on page 13.
Regularly check that the platform is level
To get the best results out of your Afinia H-Series 3D printer, the print platform must be perfectly
lined up with the Nozzle. This means that when you set the nozzle height, the nozzle should be
exactly the same distance from the platform at all four platform corners and in the center. If this is
not the case, please follow the Leveling the Print Platform procedure detailed on page 13.
