3 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 lifted up as it is printed. Photo-curable resin Platform Support Liquid material vat Projector 1. UV light applied from below using projector 2. Platform rises up, and resin goes between liquid material vat and platform Steps 1 and 2 are repeated, and job is lifted up as it is printed 1

5 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. 3

6 4. Creating monofab Player AM Data 1. Start monofab Player AM. 2. Import STL data. Click [Import] and select a file. In this example, the downloaded sample data "Funny_Horn_ARM.stl" has been imported. Data error are displayed using red lines or different colors When the model is selected, it is possible to configure settings. If the model is not selected, select the tool and click the model. Not selected Selected 4

Correct the problem areas using CAD software or similar 3D modeling software. monofab Player AM display Position the model in the work area (within the white frame) Work area The orientation of the work area during printing is actually the opposite of that shown 5

8 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]. Axis: X Angle: 60 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. Select "Bottom plane" Z: 5.00 mm Main view Check that the model is inside the work area. 6

Parts extending upward do not Printing direction More supports Supports Less supports require supports 2.

9 Tips! Positioning the model Position the model by changing its orientation, angle, and position. 1. Changing orientation Number of supports can be reduced, making finishing work easier. Parts extending upward do not Printing direction More supports Supports Less supports require supports 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 flows off, and prevents resin buildup from hardening on surfaces. Printing direction Printing position moves diagonally 7

10 3. Changing height Corrects irregularities in platform and improves print quality. Prevents model from being damaged when removed from platform after printing. Platform Leave a gap of about 5mm 8

11 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 9

Locations where supports are necessary Parts that look like "islands" Parts that do not have supports and appear to be floating in mid air 10

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.

13 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. 11

14 Supports Necessary supports differ 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. Delete supports above the red line Supports below the red line are necessary to support the model "Horns" need supports "Tail" needs supports Deleting supports reduces the amount of resin required and enables a smoother finish 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]. 12

15 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. Example of incorrect display 13
