I want a small portable 3D printer with high quality printing results. I have Mini Fabrikator II printer, which is pretty small and light. But the quality is not good enough for me. And it’s also a bowden printer with its own flaws. So the mission is to design and build a small direct 3D printer.<\/p>\n\n\n\n

I rarely design something beforehand, so going to design it partially on a fly. And here I’ll write about its progress. Enjoy!<\/p>\n\n\n\n

At the end of this page, I’ll list parts I used and their sources and prices.<\/p>\n\n\n\n

First idea was to use 8mm rods. But at the same time I was curious about rails. What if I’d use a rails for it? So I went with the rail idea. As a printhead I’ve planned to use E3D’s Titan Aero extruder.<\/p>\n\n\n\n

E3D released a new, smaller and hopefully better extruder Hemera. So I swapped Titan Aero to Hemera, as it’s smaller and lighter.\u00a0

2019-12-16<\/strong> X-axis parts. Stepper motor holder, idler holder and bed carriage. I had a long twiddling with a stepper position and finally came with this version. Waiting for the 20 teeth pulleys and GT2 belt to arrive. After printing parts I found out that I’ve ordered wrong sized carriages. I needed MGN15C but ordered MGN15H. The difference is their length, 41mm vs 59mm. The rails are 150mm long. So 59mm carriage will move only 91mm. So ordered the C carriages, as I want to use whole 100x100mm bed.<\/p>\n\n\n\n
