SparkMaker FEPvat resin vat

The SparkMaker FEPvat is a great alternative for the standard SparkMaker Resin vat. It’s 3D Printed and made from high quality resin resistant filament. It has brass inserts to ensure the stainless steel bolts keep gripping with time. No more messing arround with little nuts. The FEPvat is build to be strong and functional. Well over a hundred FEPvats found their way into the hands of customers. Some of  these VAT’s are in use for more then 12 months now and they still work perfectly. We found one in a corner of the workshop holding resin for more then 6 months! They keep great after many FEP sheet changes, resin changes and cleaning with alcohol. The novelty of the vat is the unique tensioning ring. This ring makes it easy to thighten the FEP film and also creates a double seal that almost guarantees the FEPvat won’t leak. But ofcourse they are not build for eternity, and we cannot make long term guarantees. But hey, we can guarantee they last longer then a Formlabs resin VAT costing three times as much!

SparkMaker FEPvat features

1: Easy to use
We developed a two step sheet mounting system. The first step locks the sheet so it wont move around any more. The second step thightens the sheet till its perfect.

  • Step 1
  1. Turn the FEPvat upside down
  2. Lay your FEP sheet on the FEPvat
  3. Press the ring into the FEPvat till it’s flush with the edge. You will feel resistance, just push till it’s flush.
  4. Insert all bolts and tighten them. Keep the ring flush with edge of the FEPvat.
  5. The FEP sheet is now locked in place.
  • Step 2
  1. Thighten corner bolts till secured
  2. Thighten all other bolts till secured
  3. Ready, your film should be thight like a high pitched drum now!

2: Let it drip
The FEPvat can stand on it’s side. It sits at an angle so all resin will drip out. The wall is formed in such a way that resin always drips out in the center.

3: Let it pour
We incorporated a little spout to make pouring resin from the FEPvat as easy and clean as possible.

4: Not only better, it’s bigger
We made this FEPvat a little higher and slope the side walls to maximise resin volume. And BTW the sharp edge at the front is a great place to scrape excess resin of your spatula after stirring resin.

    This VAT is much better than the original that came with the printer. I installed the FEP film first try no leaks. Instead of just pushing on the film I first poked holes in the right places put the longer bolts in from the old VAT just to hold the film better and then pressed it in place.

    One biggy, the new VAT is taller and so the old bolts are too short to install it in the printer. So I have a working VAT but I still can’t use it right away. Have to look for the right bolts now. There are bolt in the image but they don’t come with it so its a little misleading.

      Thank you for your great feedback.

      You don’t have to puncture holes first. When you press the ring in lightly and keep pressure the sheet it cannot move.

      We are very sorry about the short bolt issue. We are so used to using these (longer) handy thumbscrews, we totally forgot the standard screws are shorter. So from now we add 2 thumbscrews to every FEPvat.

      Your thumbscrews are in the mail!

    Too bad this vat isn’t original equipment. The one that comes with the printer is complete crap compared to this. My original vat leaked and had a really bad film on it. The first prints I made with the original were total failures. I used this vat with film that I also ordered from here and had a great print the very first time. No leaks and great fit. The thumbscrews also make it super easy to remove.

    This is much nicer and much bigger that the official vat that comes with the original spark maker. I have used it for a few months and it has not warped on me. my only issue is the drain spout does not work very well. That could use a bit of a rethink.
