ok for the 3d printing of the "structure" but then how to make it reflective? do you use regular allumination chamber or what technique ? which precision you can achieve to validate the prototype ?
- lutorm 10y agoObviously it's for a metal 3d printer...
- AlexTes 10y agoI don't think so. The cost would be extremely prohibitive. It would be far cheaper to print it in plastic and then add some reflectie coating.
- sgnelson 10y agoMost metal 3d printers simply don't have the surface finish to make this feasible, never mind cost (it'd be ridiculous).
- lutorm 10y agoI guess i should have added a ;-). Although the laser sintering printer downstairs produces quite nice surface finishes. Not good enough for an optical mirror, but definitely good enough for mm-wave antennas.
- noonespecial 10y agoI've had outstanding luck with this paint (1). Print your model in ABS. Smooth it by putting it in a paint can on a little stand with some acetone soaked rags below for about 1/2 hour. Paint with some of this paint. You will be amazed.
