In the SmartXp we have a **Lasercutter** for cutting and engraving materials. This facility is mainly educational projects within the faculty, but we also facilitate other (private) projects.\\
{{:speedy_400_01.jpg?direct&300|}}

**We have some rules;**
  * You have to pay for materials.\\
  * Your design should send to smartxp-laser-3d@utwente.nl.\\
  * Maximum size 990x590mm - but this depends on the material.\\

**Design rules:**\\
  * Hairlines are lines with a thickness of less than 0,11 mm.
  * Cutting-lines must be RGB red [255,0,0] hairlines(vector). These lines will be cut all the way through\\ 
  * Etching-lines must be RGB blue[0,0,255] hairlines(vector). These lines will be cut halfway through\\ 
  * Placement-lines must be RGB green[0,255,0] hairlines(vector). Nothing will be done with them, they can help with placement or other info\\ 
  * Other lines thinner as 0,11mm are considerd to be hairlines however it is unpredictable what will happen.\\
  * Engraving parts are greylevel lines/parts or bitmaps. Black [255] is highest engraving power, white least [0].\\

  * fileformats: cdr, dxf (only single parts or proper Fusion exports), eps, ai.
  * Mention details like material and thickness, preferably in the file. You should mention theses sizes to avoid conversion errors.
  * 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! so check for them!**\\
