Laser cutting & 3D Printing Tips
From CHS Sigma
- In general, most acrylic sheets are 3.18mm thick, however always measure the thickness of the sheet you will use because the thickness varies widely
- This dimension should help with drawings
- The laser cutter cuts off approximately .07mm of extra plastic when cutting
- For example, if I were to friction fit a piece of acrylic in another, I should make the width of the hole .14mm smaller than the desired width
- When trying to achieve a friction fit between a laser cut part and a 3D printed part, no adjustment is needed, as the 3d printer will add a little material.
- Save drawing as Adobe Illustrator file (.ai)
- Sheet size 600mm x 300mm
- Remember to make sure you are using a 1:1 scale in the Solidworks drawing
- In Ai:
- Vector cut lines should be red = 255, green = 0, blue = 0 (which also means everything must be in RGB mode)
- Lines should be 0.025 thick or less
- In Laser Cutter
- Material - Plastic - Cast Acrylic - Cast Acrylic
- Material thickness 3.175mm
- Remember to click apply before OK.
