Not sure what your looking at, but if it's the blue chess pieces, that finish is because the rigidbot was a very very early printer and I believe I printed it with 0.3mm layer heights. You can reasonably go down to 0.15mm or possibly 0.1mm but it double or triples the layers required and therefore the time. For truly smooth layers you need sla or abs and acetone bath (not recommended).Can you (anyone) get a finish straight off the printer that isn't so rough? That seems to be the way I see MOST come out. Now I do see may things Clough42 makes, and they look pretty smooth. I don't BELIEVE he is doing sanding and such, so I am curious if there is way/material/technique.
Yes, it's doable, but the chess pieces are 3" tall and I printed 32 of them even at 0.3mm layer height it took 3 or 4 days to finish. Each section of the spitfire was printed at 0.2mm layer height and the larger pieces take about 18hrs each. For parts the size your showing, I'd go sla and have no layer lines. It's a trade-off. If I printed the plane or the chess set at 0.1mm it would look very smooth but take a month...........I've made some relatively smooth parts... headlight assembly for a 1/14th scale Peterbilt truck. Tiny one is a radiator for a matchbox car.View attachment 329229 View attachment 329230
Were those printed on your Prusa? If so, what was your layer height and nozzle size?I've made some relatively smooth parts... headlight assembly for a 1/14th scale Peterbilt truck. Tiny one is a radiator for a matchbox car.View attachment 329229 View attachment 329230
