Build Your Own SLA/SLS

hello guys,

i´m currently developing/building a 3d scanner, a powder-based printer and a sla printer and so i can just post a screenshot from the cad system right now.

the scanner will be based on david laserscanner with full-hd projector which will be mounted on a slide to have it easy changed between the scanner system and the sla printer.

Hi!
Nice design.
Can you please explain a bit more how you intent to print with Powder?? I am not aware of this possibility with a projector.
Regards

Hi,

it will be a different project and not based on a projector which i´m not aware of an possibility, too.

I think using a projector for both the laser scanning portion and the DLP-SLA display is a good idea. I had a similar idea for my next pico-projector machine. How close are you to building this machine?

I´m waiting for a group of students of mine which are building a furnace unit and when i´m ordering their parts, i´m also ordering mine in the same order. i hope to get started in the next weeks. Next week i´ll develop the powder printer and hopefully i can place the needed components in the same order.

What powder are you thinking of using, I built a couple some time ago, the problem is the dust and mess they make.

The PWDR project has plans for an open source powder based printer. It hasn't been updated in a long time, and I haven't heard anything about it recently. From what I heard from a few folks at Defcon this past year, software support for it is almost non-existent.

As time passes so fast, there is some slow progress z-axis will be machined next week, based on strong aluminum.

I hope its finished within the next 3 weeks. electronics is ready and waiting for the mechanic parts.

Finally the first successfull print, which was the third at all. The first two prints failed due to resin not attaching to the build plate, so i gave it a good roughing and unfortunally now the resin sticks like its been glued together I´m trying the fridge to cool both parts to minus 20°C and have a look if that will help.

I´m using SubG+ and 100µm layer thickness, i wanted to try printing at 50µm but found some guys giving advice to NOT print at 50µm with that resin, so i will stick with 100µm by now.

A big thanks to pacmanfan to share that awesome peace of software making machines like ours possible
