Formulas for home brewed photosensitive resins.
I thought it might be interesting to start a thread on formulas for photosensitive resins. I remember years ago I experimented a bit on the subject, creating a very simple yet practical UV sensitive resin mixing Polyester resin with Potassium Dichromate. Potassium Dichromate is a very powerful oxidi...

Re: First semi-successful print
And the winner is CW anti-aliasing feature.
Same or better results minus the hassle.
Thanks again Steve!

Re: First semi-successful print
You can also use the Anti-Aliasing feature in the slicing profile, works very nice at about 3.5. I believe this does pretty much exactly what you have planed to do but without all the work involved. Clinton Hello Clinton, Thank you for the suggestion. I will compare both methods and post the result...

Re: First semi-successful print
How is oversampling performed? Only from what I have read, it appears that LED projectors don't have the power of the mercury lamps, and need more time. How will you determine what LED projector is best? I'm considering purchasing the Acer H6510BD. But if a LED can build a layer just as fast as a 3...

Re: First semi-successful print
Thank you Steve. I'm still practicing and learning. Here's another print from a 3D scan I made of me and my wife holding hands and using Agisoft Photoscan to capture it. I am only scratching the surface on the capabilities of my machine, the combination of FEP with passive tilt and the fused quartz ...

First semi-successful print
Well, I finally had a chance to test my printer. I ran it at .1mm resolution on the Z stage, I still have to adjust the XY resolution since the rabbit came somewhat flat. The computer video card send the monitor to sleep right in the middle of run, which caused the projector to run at full intensity...

Re: SLA Project built with (mostly) recycled/salvaged parts.
Hi! Congrats for your printer!!! I like it!! Can you extend the explanations on fused quartz plate? Source? Price? Thickens? Thanks in advance. Reagards Thanks!! The main reasons I chose Fused Quartz, which is nothing more than super pure Fused Silica with no additives added during manufacturing, a...

Using a corexy driven laser.
I've been thinking about creating a corexy driven laser for resin exposure instead of using a galvo.
I know speed would be greatly decreased, would resolution suffer also?
This is an interesting link about the subject with schematics: http://corexy.com/corexyr1/index.html

MakerJuice's SubSF resin is here with a little premium (how did they know Jolly Rancher candies are my favorite?)

Re: SLA Project built with (mostly) recycled/salvaged parts.
I've decided to use a mirror to reflect the projected image. This way I can experiment with different projectors. I already have a whole bunch of first surface mirrors which I got from an old projection TV and cut down to about 8" x 8". Almost there!!
