1. Getting Started
■ What is layered projection technology?
Layered projection technology is a technology that allows the creation of precise solid objects by hardening
built-up layers of photo-curable resin using UV light.
It makes it easy to create hard-to-cut shapes and models with undercuts.
■ Printing with the ARM-10
The ARM-10 uses a projector to harden resin by exposing resin under UV light from below. The job is lift-
ed up as it is printed.

2. Platform rises up, and resin
goes between liquid material

Steps 1 and 2 are repeated,
and job is lifted up as it is

3. Preparing 3D Data
■3D data
In this example, downloaded data is printed as a sample.
Tips!
Use CAD software or similar 3D modeling software to hollow out the 3D data you will use.
(Hollow area indicated in red in image below.)
Hollowing out dense sections of the object reduces the amount of resin required, which
makes it easier for the printer to lift up the job and prevents the job from falling into the
liquid material vat.

1. Start monoFab Player AM.
2. Import STL data. Click [Import] and select a le.
In this example, the downloaded sample data "Funny_Horn_ARM.stl" has been imported.

When the model is selected, it is possible to
congure settings. If the model is not selected,
select the tool and click the model.

3. Heal error with the data using the Healing function.
Select the "Layout" tab and click [Healing]. Click [OK] when you have nished.
If error with the data are not corrected...
Correct the problem areas using CAD software or similar 3D modeling software.

4. Position the model. Set the angle, position, etc., of the model based on its shape.
In this example, downloaded data is set.
Change the angle (60°)
On the "Layout" tab, select [Rotate], and set the orientation and angle.
In this example, we have set an angle of 60° in the X axis. Click [Rotate].
Change the height (5 mm)
On the "Layout" tab, select [Move], and set the model position.
Select "Bottom plane" and set the Z axis as 5.00 mm.
Click the main view (screen) to change the position of the model.
Check that the model is inside the work area.

Tips!
Positioning the model
Position the model by changing its orientation, angle, and position.
1. Changing orientation
• Number of supports can be reduced, making nishing work easier.
2. Changing angle
• Makes it easier for printer to lift up job, prevents job from falling into liquid material vat,
and improves print quality.
• Delays deterioration of liquid material vat by moving printing position.
• Unnecessary resin ows o, and prevents resin buildup from hardening on surfaces.

3. Changing height
• Corrects irregularities in platform and improves print quality.
• Prevents model from being damaged when removed from platform after printing.
Leave a gap of about 5mm

5. Generate the supports that connect the model to the platform.
Select the "Supports" tab and click [Generate Supports].
6. Check the supports.
Select the "Print" tab, and click the [ ] (Cross Section View) button on the toolbar. Dragging the
green frame displayed in the cross section area up and down (in the Z axis direction) lets you change
the position of the cross section.
This lets you check whether supports are attached where they are needed.
Drag green frame up and down

Tips!
How to check supports
The job will not print correctly if supports are not attached where they are needed. Check
that supports are attached on parts that are not connected as shown below.
Parts that do not have supports and appear to be oating in mid air
Parts that look like "islands"
Locations where supports are necessary

11
7. Delete unnecessary supports.
On the "Supports" tab, select "Add/delete support point", and click [Select point to delete].
8. When you click a support point, a red cross appears. Select the points you want to delete, then click
[Update supports]. Repeat the process and delete all the unnecessary supports.
There are a lot of unnecessary supports in this data, so it is necessary to check from all directions and
delete them.Green + marks indicate important points. Do not delete the green support points.

12
Supports
Necessary supports dier according to the shape of the model.
Refer to the model below as an example of which supports are necessary and which supports can be
deleted.
Deleting supports reduces the amount of resin required and enables a smoother nish after printing.
However, if more supports than necessary are deleted, there is a risk that the remaining supports will be
unable to support the model, which may drop into the liquid material vat.
If there are no supports in necessary locations...
On the "Supports" tab, select "Add/delete support point", and click [Select point to add].
Select the position where you want to add a support, and click [Update supports].
• Delete supports above the red line
• Supports below the red line are necessary to support the model
• "Horns" need supports
• "Tail" needs supports

13
9. Check the preview.
Select the "Print" tab and click [Display Preview].
If the model doesn't look the way you want it to...
The model may have an error. Correct the data using CAD software or similar 3D modeling software.

1. Hollow out data
2. Position model on an angle
3. Set height at 5mm

5. Preparing the ARM-10
■ Attaching the liquid material vat
1. Loosen the liquid material vat retaining screws.
2. Insert the liquid material vat. Check that there is no dirt or foreign matter in the liquid material vat.
Push in the liquid material
vat until its edge gently
touches the shutter lever
3. Securely tighten the liquid material vat retaining screws.
Check that the liquid material vat stopper is
resting on the edge of the liquid material vat
In the next step, the liquid material vat retaining screws are loosened by a xed amount. For this reason,
the liquid material vat retaining screws are tightened securely at this stage.

4. Loosen the liquid material vat retaining screws one turn.
5. Push in the liquid material vat all the way. Take care not to get ngers caught between the liquid ma-
terial vat holder and the liquid material vat.
6. Securely tighten the liquid material vat retaining screws.
Liquid material vat
If you print repeatedly in the same location, the liquid material vat will turn cloudy white. When the liquid
material vat gets cloudy, resin stops hardening, the job sticks to the liquid material vat, and printing
becomes impossible. Change the position of the liquid material vat or position the model so as to avoid
cloudy areas. If it is not possible to print, replace the liquid material vat.

■ Adjusting height (Z0)
Always adjust the Z axis height after replacing the liquid material vat. There is no need to adjust it for
every print job.
1. Using a hexagonal wrench, loosen the four Z0 adjustment screws.
Loosen each screw so that around 2 mm of the shaft is visible, and check that it is possible to move the
platform up and down by hand.
Z0 adjustment screws
(both sides, 4 locations total)
2. Close the front cover and press the power button.
3. Select the "Print" tab, and click the [ ] button. The platform descends to the bottom of the liquid
material vat.
4. When the platform has stopped moving, tighten the Z0 adjustment screws while holding down the
platform as though gently pressing it against the liquid material vat.
Before fully tightening the screws, temporarily tighten opposite corners rst to ensure that the screws
are tightened evenly.

5. Close the front cover.
6. Click the [ ] button. The platform moves to the highest position.

■ Adding resin
1. Check the amount of resin required.
Select the "Print" tab, and click the [ ] button. The estimated job volume is displayed.
2. Put on the rubber gloves and protective eyewear.
3. Using the estimated job volume as a guide, measure the resin and put it in the liquid material vat.
Adjust the height of the ARM-10's legs before use.
Do not ll with resin beyond
the FULL line.
