After completing my visco machine and ending up with something functional but not great, I'm thinking there are more than a few people out there like me who can't easily buy visco fuse and don't have the tools to manufacture their own Visco Machine to produce it.
I've recently gotten into 3D printing and acquired a laser cutter so now have all the tools at my disposal to make a much more professional and capable machine. What would be the interest if I were to design up something and offer it as a kit?
I've only got a very rough idea but here are my thoughts.
200mm-300mm cubic footprint. Hopefully I can keep it to 200mm
PLA and Acrylic components
Independent speed controlled spindles and winder via stepper motors for tuning
12 threads per spindle to produce roughly 2-2.5mm visco (after coating)
90 degree drive so first spindle is vertical and second spindle is horizontal. This should minimise powder dusting the second spindle, reducing the chance of visco taking fire from its side. Also much easier to load and clear jams
Should be able to produce fuse at a minimum of 4m/minute.
In the kit would be a flat pack style acrylic frame and spindle with printed dies, bearings, gears, fasteners etc. Basically all hardware required.
I would have to finalise the design and get a better handle on time taken and material cost to produce each kit but I'm guessing somewhere around the $150-$200 USD mark.
Stuff that would be purchased separately as they are readily available
It would require 3 Nema 17 stepper motors, an arduino mega or clone, ramps 1.4 with 3x stepper drivers and a 12V lower power supply totaling about $100 USD.
So let me know if you are interested and if there are enough people, I will put the effort into creating a design.
