Excellent device. Fast seller and shipping

Great for small projects ,model building annd crafts

I am not a dentist. I don't use this for what it was intended for, but I do make moulds in much the same way.It's a small envelope to work in, but if that's what you need then this works great. You can VERY easily burn your styrene or whatever you're using as the heating element is more than adequate. The vacuum is also super impressive. My first pull on the machine, I overheated the styrene and when the vacuum turned on it ripped a million little holes in the styrene. My fault, but my goodness what a vacuum!

I use this to make vacuum form canopies for my ww2 warbirds and it works awesome.

This machine has a great internal vacuum and the heating element runs hot enough to tackle most forming materials. It has a few things that really bothered me though. The first major issue is that the screws that hold the perforated screen into the metal frame on which you place the item you are forming on protrude significantly above the plane of formation meaning the true usuable bounding area is cut away on each corner by about 1/2 an inch (see picture for my best actual measurements using calipers). Given that the bounding area is already tiny this swallows up a large chunk of your available work area unless you 1) replace the screws with a different headless fastener 2) you rest your item on top of the screws and deal with the additional wrap around 3) you remove the screws and deal with the loose screen 4) you try to use the steel balls they include.... which leads to the second major nitpick... the balls aren't round or smooth, they are rough, even faceted... so if you try to form on top of them expect a ton of them to find themselves imbedded in your plastic afterwards and spill everywhere unless you take tons of time trying to tap them out (which inevitably never gets them all out). These issues are minor but its these details that separate a truly user friendly experience from the hassle of having to modify what you are working with in order to get to the level of manufacturing the original manufacturer should have taken the time to refine their end product to to be a truly excellent product.
