Building a Large Format 3D Printer – Part 4: Printing

Video Description: Part 4 of the Large Format 3D Printer series dives into printing large complex geometries. From a 18 kg (40 lbs) chair to a step stool with gyroid infill, Dr. D-Flo explores the capabilities of his pellet extruder and massive 4’ x 4’ x 4' build volume. However, these large prints come at a cost, and the amount of material ($$$) and power ($) per print are evaluated in this video. To keep the hungry extruder fed with pellets, a Venturi vacuum-based pellet conveyance unit is installed to "blow" pellets from a bin to the extruder when needed. This system has worked flawlessly for over 100 hours, but there was one catastrophic failure that had to be overcome (stay tuned until the end to see this blooper). This video also touches on the mechanical recycling of failed prints, but a future video will go into much more detail on turning plastics destined for the landfill into pellets for the large format printer 3D printer.
