Okay recently iv been thinking of ideas for a 3d printer based on MPCNC. Saved up 300 quid ( $400). Brought everything i needed and still had half left so i fort what else i could do.
With Tinkercad being my new microsoft paint ,i went on thingiverse,saw what i liked and pasted it together. Any help with my design would be much appreciated, Just need a bunch of objective people to look at it and say what they would improve or change. Also any other ideas. please fire away.
The print head is a quad print head, with 4 volcano heat blocks, there slightly longer allowing for a larger diameter nozzle, iv got a 0.2mm which is my standard. a 0.4,0.6 (32% faster) and 0.8. this will effect the quality however. but as i will only be printing parts for projects, id much rather print on a 0.6 and knock 2 hours off a 7 hour print time.
This does mean however the printer will also consist of 10 stepper motors, squeezed onto a ramps board. Will power half the motors from a separate power supply, using the ramps only for the control signals.
Pictures below. Im still thinking about the paste extruder but heres the general idea, the syringe needle will be seated inside a enclosure allowing for it to be at the same level as the nozzle. Im also designing a encoder mount, for a large digitising arm i am wanting to make.[attachment file=“QUADHEAD.png”]
