Hi all and again thanks to Ahmet ( from the Yahoo group )for sending a sample to me.
I have tested extensively the Adhesive backing FEP Teflon and am abandoning that
route for now. It seems to have the same problem as straight
polycarbonate/nylon/Polyethylene. It is difficult to separate the resin ( at
least mine )without it actually coming off the glass base. You could be using a
different resin with different results, but for my purposes it does not work.
Time to marry these two together.
For now I’m just folding the film in place.
I used some clips and an old ruler to cut two pieces 95mm in length:
and stretched the Teflon Film on top of the glass. It kind of clings to the glass by itself.
Just secured it on two opposite sides:
That is it for now… Later!
That time of the year for a new VAT again.
After some calculations a few posts back I realized I will have to add resin midway if I print a larger object, hence the current post and need for a bigger VAT.
If you need to print a smaller item, the VAT may prove too big, but you can always drop a block of 70mm x 90mm x 10mm glass and use less resin.
This time it is all glass with a bit of 100% silicone.
1- 200mm x 150mm 5mm soda lime glass ( regular window ).
2- 200mm x 20mm x5mm of the above.
2-100mm x 20mm x5mm of the above above.
Mark the location of the walls lightly with permanent marker.
Spread some silicone on the bottom edge and the side edges and repeat on all 4 sides.
Use some tape to hold the glass in place after you glue it. Leave it undisturbed at least overnight.
I slid out the glass window, but left the aluminum rails and inserted the new VAT and tightened the grub screws.
