LittleRP Compatible Flexvat Kit With Vented Acrylic Support , 4 FEP, 4 Gaskets, 2 Acrylic Support Plates, 48mm X 68mm Build Area. Available With Or Without Easy Leveling Build Plate
The LittleRP Compatible Flexvat With Acrylic Support in most cases will have similar part peeling characteristics to the Drumhead Flexvat with the advantages of having a lower focal plane (6.5mm) and the elimination of the need to adjust the tension of the FEP film. The Flexvat is made of solid cast polyurethane and uses slightly tensioned transparent teflon film (FEP) sitting on a transparent acrylic support as the release material for the Flexvats floor. When 3d printing using FEP as the vat floor the FEP film acts like a flat and rigid surface when the build plate is dropped and an exposure is made but then behaves like a mechanical peeling mechanism when the build plate lifts between exposures. When the build plate lifts after an exposure the FEP film will lift slightly at points where the part being printed are sticking and peeling edges appear anywhere the part sticks to the film, because of this tilting or other peeling mechanisms are not needed when using this type of vat. This vat design uses a "raised edge" under the FEP film which improves the ability of parts to peel away from the film while printing.
The "reservoir" design of the flexvat allows you to have more resin in the vat without having to worry about overflows, this design also gives the resin somewhere to go when the printers build plate is raised and lowered while printing. The FEP film vat floor is also very long lasting 50 to 100 prints or more being typical also because this Flexvat is constructed from cast polyurethane it is very rigid, durable and chemically resistant.
This Flexvat can be used with any resin based 3d printer that can project and focus layer images 6.5mm above the surface the vat sits on and can be adapted to many 3d printers by creating an adapter or printer platform using the window and hole layouts found on the DIY And Technical Info page.
The Flexvat kit is shipped partially assembled so you can be printing in as little as 5 minutes.
