It's perfect!

I tried the idea for the supports that I wrote yesterday, the result was very good.
The bridge, also works effectively.

2mm support test

This is a test for 2mm support. Some supports were missing, but I think it's not so bad result. Making the supports at the outer edge of the basement is difficult. I have to make them could re-generate when it's missing at first step.

Refocus succeeded

I checked a projector focusing on the vat again, the result of printing would be very good. Only one place, a support wasn't generated. So there part was incomplete, but almost good shape in terms of accuracy.

I think a cause of the failure, there is a subtle difference in the angle between the surface of PDMS(bottom of vat) and build plate. The thickness of the basement on this side is thinner than the other side. The basement on this was peeled off at the first process, so the support parts weren't generate. I have to recheck the degree of adhesion between the PDMS and plate.

Setting the projector focus again.

After the last post of this blog, I tried several tests again. But I couldn't get surely good results. The details under 2mm were not shaped. A model like this is no problem to shape. So, I checked the projector focus again, and print test once more.

99% OK

It's finished the printing of 'BUG' in this morning.

The result was almost good! Only one finger was lacked. And there are much of blobs in the resin made by last test. So, I filtered the resin in vat for next print.

Good result!

After failing several times, I finally got the best position of the build plate.

I Attached 4 layers on basement, printed the models for testing the support shapes. The result was very good. all the shapes were printed perfectly.

So now, I'm trying the 'BUG' model again. That model has over 900 layers on 50µm/layer mode, I have to wait about 17 hours to end.

Test again! but print aborted...

I made more fat model, and printed. But, the printing was aborted on final 3mm. Why...?
And I still have a problem about the 'Support' parts. Some legs were gone, and some wings get strange shape.
I have to test first that what shape of supports are good for print without peeled off from the stage.
