Laser Stereolithography 3D Printer

[dnar]

Here is a very simple home project for you. I have used commercial epoxy printers in the past for prototyping, it's very cool tech.

This is a lot simpler, yet worth a go I feel.

I'd love to see if he can get the fluid viscosity right, and find one that activates quick enough at 405. That is one tricky fluid to work with, at least it was on the commercial unit I worked on. I hope he gets it to work. Our doctor knife made a .004" layer on each pass. You also have to get rid of any surplus fluid on the object, plus bake your finished creations.

We had the record, as far as Melles could tell, for the longest living UV HeCad in 3D litho service.

On that unit, two G120s scanned through a 4" F-Theta made for UV, and the resin was slow enough that a ledex solenoid was the shutter. The G120s had heaters to stabilize the position sensors and there were external sensors for beam position, as well.

i was just thinking that i know someone with a pair of g120's and a f-theta..

Here's one I made earlier...
The resin system is sorted, and allows for multicoloured parts.

Wow! You da man!
