  1. Muy buen trabajo, Sólo una duda. Tenía entendido que lo de cerrar completamente estas impresoras provocaba que los "steppers" se vieran sometidos a mucha temperatura, y que todo lo que sea pasar de 60ºC suponía riesgo de cargarselos. ¿No has tenido ningún problema al respecto?
  2. Hi! I am using Ultimaker 2+ for prototyping components of machines. These parts are not geometrically complicated nor have fine details, but I want these prototypes to be more or less functional, so the priorities are: - Dimensional stability (the lowest warping) - good mechannical properties (specially critical is the layer adhesion). Up to now, I have used PLA, which has a good dimensional stability, but its mechannical behaviour is not so good, and ABS, which is quite stronger but only works well when the pieces doesn't have long and straight faces or walls (contraction issues: warping and interlayer cracks). I have also tried HIPS, whose contraction is a bit lower than ABS, but still warps quite a lot if the piece has a high infill and straight walls (besides, its adhesion to the build plate is very soft). I wanted to try nylong, but it requires managing humidity... According to your experience, which material is the best for functional prototyping? Thanks in advance
  3. Hi all, I am a new user of Ultimaker 3D. I used another 3d printer (Zortrax) in my previous job, but i used it for other purposes. Now, among other things, I would like to print non-functional mockups of some devices (machines) starting from the 3D engineering models. When scaling a model (i.e. 1:10) some elements geometries become too small to be printed (i.e. the thickness a tubular structure). Since the mockup doesn't need to be functional, I don't need to reproduce all the details (screws, fittings, hollowness of tubular structures, etc.). Is there any tool that simplifies a 3D model in order to make a more consistent miniature? Or shoud I create a new model for 3D printing? Thanks in advance.
