The machines could be described as bulky, though they have a pretty modest footprint. The SioPress has a roughly 3x3' footprint, 5' tall and 600 lbs. The SioForm1 is 2x2', 6' tall and 700 lbs, roughly. So they are quite heavy, but they really don't take up much space, though they should have a bit more room around them for operation. I am in Ventura, California, about an hour and a half north of LA.
To get the machines running you would need an air compressor capable of at least 6 bar and specialized power outlets installed by an electrician (the power requirements are a little weird because the Spanish manufacturer did not change them for the US). I believe each machine needs 15 amps dedicated to it. Not impossible to do in a home setup, if you have extra space on your main panel.
There are no instructional videos, but there is a lot of documentation and SioCast offers training courses that I believe they charge for. There are other US companies that have the machines that might be willing to mentor, I don't know. Making the molds is easy to learn, hard to master. It's similar to sculpting, in a way. What we were doing was 3D printing a mini and pressing that into the mold, then building up the mold all around it to make a perfect seal before placing the other half of the mold on top of the mini. You then bake the whole thing in the SioForm (the technical term is "Vulcanizing") and you have a finished mold. Getting something wrong with the mold before vulcanizing it is what results in layer lines. Then you need to put the finished mold in the injection machine and dial in the pressure and temperature settings to make it shoot just the right amount of material at just the right temp. It's a fiddly process, and getting it wrong results in flashing. As you can probably tell, there is a lot of trial and error involved. There are companies with SioCast machines that will make molds for you, and they might even dial in the settings and tell you what they are, but obviously that costs money.
