Aha that's good to know. Justifies the huge printer then! Kind of a shame though since filler and paint was part of my plan to make some parts in the future. But from what i've heard of ABS it's a real chore for large parts. |

Is there an accepted definition for a "Large" 3D printed part? If so what is it? Don |

Don --- End quote --- I don't think so, and it's part of the problem I had trying to find stuff to look at just going through google. Those huge novelty 3d printers and bogus grant projects suck up alot of the attention and search results. |

I'd classify "large" parts as bigger than about 6" in the longest dimension. As for finishing large parts, it's a function of "how pretty" and "how often". If you make an acetone vapor unit for your largest part, then you can make a big improvement quickly. I've done that on parts up to about 6" tall; I printed a riser tube for my rice cooker and covered it with Aluminum foil tape. There is a special epoxy resin for filling the grooves, but I haven't tried it yet. The attached photo has a cat hole about 8" tall, mostly finished to fully smooth with a file. Each side was probably an hour worth of filing. Sent from my SAMSUNG-SM-G891A using Tapatalk |

And only this. https://www.gumtree.com/p/printers-scanners/3d-printer-anycubic-kossel-pulley-assembled-with-auto-level-sensor-/1312934735 Not about to rush out to buy the first thing that appears, and i'm not super psyched about delta machines, but doing a quick read suggests its a RAMPS1.4 based thing. Which along with an arduino, 4 stepper controllers, and 4 of the cheapest motors on the one website I was looking at comes to just about £100. That'd also not be including a power supply or the whole extruder deal. Hot ends look easy enough to make with a lathe. So I guess that asking price isn't too riddiculous, but I still don't think it'd be Massive Savings over buying the parts. Especially since I don't think that machine itself looks very good. --- End quote --- I have a half built Anycubic Kossel - linear rail version. I have swapped the hotend for a genuine E3D V6, the 12V power supply for 24V, the bed heater for a 240V SSR controlled unit and the control board for a duet (old version - not the wifi one). A lot of these parts were gathered over the years for various other projects and are being re-purposed. It doesn't ooze quality but like most cheap Chinese kits if you upgrade the parts and assembly process judiciously, they can turn out quite good. I love watching delta and Corexy assemblies move. I find them very elegant in comparison to Cartesian assemblies, so I couldn't resist when I saw them being sold for less than £200 delivered last christmas. |
