Hi Jimini, thanks for the input!
This is an idea I have actually pondered, and am still considering. In fact my initial sketches were of a machine where the molds were on a rotary table (x axis) and the dispensing nozzle was on a y axis arm. How would I be able to control which of the three valves to open? The plastic I use at 350F is similar in consistency as corn syrup, so the idea of an open/close valve may work, but would it be possible to predictably pour measured amounts at different points in the toolpath?
I'm not absolutely convinced, but I think I will still need 5 axis controllers, one for each plastic source and two for the movement. The pots will remain stationary with a hose line from the pots to the dispensing nozzle.
Another hope of mine is to be able to "retool" this with a z axis mill spindle to mill its own molds. This is the main reason I've been leaning towards the Gantry style, not to mention the many resources, plans, and expertise this site and others provide on such a machine.  |
