Didn’t turn out too bad, although ideally I need to angle the print so the suction force from the walkway is reduced. Tom. Nice. I think that would pass muster from any normal viewing distance. 2 Link to post Share on other sites
eldavo 1,981 Posted January 9 Share Posted January 9 That looks like an excellent result. Those stair panels are really going to be a test for the printer. ;-) Cheers Dave Link to post Share on other sites

richbrummitt 2,191 Posted January 9 Share Posted January 9 (edited) I’ve been pondering this phenomenon of lines when the cross section changes significantly. My experience of automation within chitubox for support generation does not give me confidence of an update to that software as a solution but willing to be proven wrong. I’ve only printed a few wagon bodies (no tilt) thus far that are of any size and I might be able to see a bit of this change in the layers happening where the sides start above the floor. What I was thinking about was why print the floor as part of the wagon? Because we can might not be a great reason. Large flat areas could perhaps be more usefully added as a separate large flat piece, perhaps from another medium. Many wagons don’t actually need a complete floor.

RMweb Gold TomE 6,041 Posted January 10 Author RMweb Gold Share Posted January 10 I posted a bit more on the layout thread about this, but here is the larger section printed last night. As I expected, printing the walkway flat to the plate resulted in some distortion through suction forces. I’ll probably try printing just the walkway & sides at an angle to try and reduce that effect next. Tom. 10 4 3 Link to post Share on other sites
Kylestrome 4,098 Posted January 10 Share Posted January 10 (edited) That is a thing of beauty and a first class example of the medium being used to produce something that can't easily be made by hand. I can't see any distortions. David Edited January 10 by Kylestrome 4 1 Link to post Share on other sites
RMweb Gold TomE 6,041 Posted January 11 Author RMweb Gold Share Posted January 11 Trying out a slightly different approach, in printing the walkway separately so it can be printed angled thus reducing the surface area. The detail along the lower edge is already much better: Tom. 14 1 Link to post Share on other sites

I am just glad it comes off in one piece most of the time. 2 1 Link to post Share on other sites

richbrummitt 2,191 Posted February 4 Share Posted February 4 (edited) Version 3 of the OK F axlebox is working out reasonably well. The first version required the holes drilling through the initial layers, which was a pain. Version 2 lifted off the bed and tried to orient in a way that facilitated cleaning/clearing of the hole. It failed due to holes in the print, being difficult to remove from the bed and the separation point not being obvious enough to see and find. The hole was still often not defined or obvious due to the over processing required for the initial layers. Now the lift part of the print has an obvious step to cut into (achieved easily with a JLC saw as recommended by Ian M) and the initial hole size is much larger allowing the cleaner to do it’s thing and the hole is clear from the off. It takes 18mins to print 3 dozen axle boxes. The border aids removal from the plate and prevents them falling through the basket in the wash machine. Each box takes about a minute to separate with the aforementioned saw. Edited February 4 by richbrummitt Incomplete sentence 8 1 Link to post Share on other sites
danmk1 29 Posted February 21 Share Posted February 21 Hi. Was hoping someone might be able to advise on a problem I've been having with a print? No matter what angle and layer height I print at I have been getting these lines on the sides of the coaches. I am using Anycubic Black with a Photon and have tried .02 to .05 layer heights at various angles, even happened when I printed flat on the bed. Thanks in advance Dan 1 Link to post Share on other sites

nebnoswal 122 Posted February 27 Share Posted February 27 (edited) A work in progress which is slowly getting closer to to finishing. It comprises 2x SD&JR 10T Ballast Brake Vans and 6 x 8T 3 plank wagons. The brake van chassis uses drop-in W irons There was some lift on one corner on the printer, so adding a skirt that can be sanded-off should help prevent this.
