So I gave up searching for a Delta Printer Design and found the time to design one, 12 hours later I’ve got this… Yes, it’s overkill, but I wanted it to be as sturdy as possible. 310 diameter bed with a Z height of around 200. I still need to work on the effector and end stop holders but most of the battle of getting things right is done
Nice looking build! Have you considered using aluminum vertices like these to get a bit more rigidity for your frame? http://www.robotdigg.com/product/395/Metal-Corner-for-Kossel-of-2020-Profile
They don’t have 8mm holes for the linear shaft, but that probably isn’t too much of a problem
Is the printer you are searching for? http://www.businessinsider.com/wasp-builds-40-foot-3d-printer-to-build-clay-homes-2015-9
@Ishaan_Gov - as with the FB2020, the idea is to keep prices down, plus the uprights are 2060 extrusion, with the bottom corner brackets being 90mm tall and 50mm deep, printed at 70% infill I don’t think the corners will be going anywhere.
Does not look that sturdy against “twisting” problem I’ve seen with most deltas is that you can pretty much twist the top part in relation to the bottom. A few diagonals never hurt anyone.
@Daid_Braam thanks, noted. I’ll see what happens when it gets built up, I can always add into it later if I do find it twists.
The Effector design is done…
I think that the arms are to long
if the arm joints are so tight they twist the frame, there is no hope of fixing that with bracing. I am not sure what is going on with Deltas I hear about frame stability being a huge issue, but on mine with printed corners and 1515 framing it is simply make it smooth flowing with no resistance and don’t allow weird of axis forces to develop in the first place. Perfectly accurate and faster than I expected. If the belts pulling on the carriages are translating torque through the arms and effector to each other and twisting the frame, oh my god is that printer messed up in so many ways, fix that before adding framing!
