IRstuff - the expert video is amazing
MintJulep - thank you for the link, making our own cnc is definitely a possibility
kjoiner - Igus robots look good, but their travel size limitation don't meet our needs, 2'x2' travel.
All - So my plan was to get a CNC of sorts and then attach a heating element to the chalk and make patterned welds to produce plastic pads. Basically, two layers of thin thermoplastic to serve as bladders. These bladders would be filled up with water, pressure not to exceed 30 psi, which would cycle temperatures, no higher then 50C. Do we know of any existing assemblies that could perform this type pf weld? the weld pattern on the pads are mostly straight line with some radius not smaller 45deg.
