Hi everybody,

I've been a silent member of this forum for a couple of weeks now. This is my first post, so first of all I'd like to say hi and thanks to everybody who contributes to this forum.

It took about two weeks to plan and one week to assembly and has the following features/ specs:

Projector:

Buildsize:
20x12x35cm

Mechanics:
2x Axis 16x4x40mm
2x NEMA 17

Any comments, suggestions and critiques are very welcome:

My record is 6cm in one hour with 0.2mm layer size... still tuning and trying different settings. For now the curing time is 5 seconds (0.2mm layer) and 10 seconds for the first three layers...

Why do you use acrylic instead of glass under ptfe?

@Steve: thanks :)
@how_eee: I use acrylic because i had to drill holes into it, to tension the ptfe film. Also small holes to remove the vacuum between the ptfe and the acrylic bottom...

Hallo Matze,

I am from Germany, too.
Nice setup and good looking first prints!
Do you use for peeling an asymetric lift of the build platform like mUVe 1?

After a unsuccessful bargain of a Form1 clone on ebay I decided to diy a dlp printer.

regards
Alex

Hallo Alex :)

Thanks a lot. It took a few days of calibration and trying out different build platforms/vats, but I'm finally finished with the hardware part. I'm using a FlexVat similar to this (http://projectsinterestsandetcetera.com ... m-flexvat/).
I think it's the best way to design a vat. It's really fast and it takes about 10 minutes to exchange the PTFE film once it's worn out or damaged. Good luck and PM me if you have any questions.

regards,
Matthias
