Be carefull when buying Acrylic plates in shops. Sometimes they sell you Polystyrene or Polycarbonate plates instead off Acrylic.
Other materials: please ask before buying anything.
Design rules:
- Cuttinglines must be RGB red hairlines(vector). Hairline is a line with a thickness of less than 0,11 mm.
- Engraving parts are greylevel lines/parts or bitmaps. Black is highest engraving power, white least.
- Lines thinner as 0,11mm are considerd to be hairlines even if they are not red and will be cut.
- fileformats: cdr, dxf, eps, pdf, ai.
- Send your design by e-mail to smartxp-laser-3d@utwente.nl .
- Mention details like material and thicknes. You should also mention the size of at least one item to avoid conversion errors.
- Maximum size 1000x600mm
- The order in which items are cut is back to front. In Coreldraw: the items on the objectslist are cut from bottom to top. When cutting “nested” objects, the inner objects will be cut first
- Avoid double cutlines!
