Re: FEP vat for the LittleRP?
I used a littleRP baseplate for testing in my printer however I am aware of the focusing issue with some projectors and the LitttleRP. A bit of overview here, the way the projector is positioned with the LittleRP limits the how close the projector can be to the vat bottom this positioning does not a...

LittleRP and Mr. Big
Some vats I have been working on. The large one is capable of printing 1080 X 1920 @ 100 microns.

Re: Torque wrench for tightening flexvat bolts
Note that the reason I designed this wrench is so people who wanted to torque the bolts on their vat would not need to spend a lot of money on a torque wrench or screw driver. Torque wrench final design. The lever clamps down on the torsion bar and locks the bit into place. Torque range for "th...

Re: Torque wrench for tightening flexvat bolts
The FEP (.005" Dupont Type A) I use is not in any way rubbery (see the photos on this thread: http://www.buildyourownsla.com/forum/viewtopic.php?f=19&t=2808&start=30 ). I torque my tension bolts for the same reason a drummer in a band will torque the bolts on his drums, consistency. A c...

Re: Torque wrench for tightening flexvat bolts
For me a gasket allows me to make a vat with a reasonably large usable area using a small number of clamp bolts. The gasket actually decreases the complexity of the vat, for example, the vat I use on my printer has a usable build area of 125mm X 175mm (excluding the curved edges) and I only need 8 c...

If your vat has adjustable tension using a torque wrench when tightening the tension bolts allow you to keep your vats FEP film at an even and consistent tension for printing and between FEP replacements. If you use a gasket on your vat using a torque wrench when tightening your vats clamp bolts ens...

Re: FEP vat for the LittleRP?
I have been asked about the possibility of the FEP breaking and spilling resin into the projector, I believe that a properly constructed flexvat is the least likely type of vat to fail and damage a projector: http://projectsinterestsandetcetera.com/wp-content/uploads/2015/05/fep-tough-1.jpg 25 pound...

Re: FEP vat for the LittleRP?
Secret info follows. I wouldn't worry about the FEP ripping .005" FEP is a very tough material a sharp knife will pierce it a hardened piece of resin probably not. Since FEP stretches up to 300% before failing the main reason for needing to change a vats FEP is "dimples" created by pa...
