My new material for VAT

Postby dragokirov » Sat Jan 10, 2015 2:44 pm

Hi, I have tested many materials but I'm not really satisfied by them. I have ordered especially for this process photolithography some nonstick material from .
This is the result:


The material is not optically clear because it is very thick and the casting-form is not polished yet. The real casting-form will be ready after few weeks, I hope.
Regards,
Drago

It looks very nice and promising. Let me know how your tests with it work.

Hi Drago,

This material seem to be very promissing !
have you some reference number to ask for some data sheet from the bulgarian institute ?

It will be interesting to have some datas about the "transmitence" regarding the frequency of UV light.
What's about the time of "lighting" and power of your UV led in the test and what is the thickness of your layer ?

Hi, Rupek
I paid for this material and I have a confidentiality agreement with the Institute. The power of UV led is 10W , the thickness is 5mm and is not polished, however one second is enough to cure the resin.
Regards,
Drago

Hi Drago,

do you intend to build VAT with "hard" bottom and install it to the frame in "fixed" manner (no tilt, slide, etc.)?

Do you think that it would be possible to get a sample when the casting-form will be ready?

Daniel

Hi daielm
That's the idea , to save time for printing and money with no tilt, slide...and the 3D printer to become more simple.
I hope that will work equally well with hard and flex bottom or just the two together. ;)
when I'm ready I will explain everything in details.
