Colin Bernard Posted February 18, 2017 Share Posted February 18, 2017 Tony, Those are impressive. From the photo there is no sign of layering and far better than I have been able to come up with so far. (Working on an Anzani for my Cambrian Pioneer.) Can I ask is it PLA? And what settings - layer height, temp etc? Colin Quote Link to comment Share on other sites More sharing options...
Tony Bennett Posted February 18, 2017 Share Posted February 18, 2017 hello PLA. 200degrees on the hot end 55 degrees on the bed 0.6mm walls and base 50 mms print speed 100mms movement speed hollow. skirt and all the rest is stock setup on my anet a8.

Simon Chaddock Posted February 24, 2017 Share Posted February 24, 2017 At the moment by far the most my 'printing time' has been spent making parts for the printer! The Anet A8 is a good machine but to keep costs down all the wires leading to the the bed and bridge have to 'dangle' to allow for the movement. It looks a little untidy and as most of the flex is concentrated over a limited distance it might lead to the wires cores fracturing over time. A quick brows through the "Thingiverse" web site confirmed that others had come to the same conclusion with print instruction available for many different types of cable track. So to gain experience in printing I set about doing the same for my printer. Of course not being entirely satisfied with the initial results many hours were spent modifying the original designs until it ended up like this with cable tracks for all 3 axis. The mains power board now has a switch and socket for a plug. The mother board is also fully covered. Nothing to do with planes but it has given me plenty of printing practise! .

Ian Jones Posted March 9, 2017 Author Share Posted March 9, 2017 Not my own design but I like it... a simple solution to not having enough fingers to hold wires together whilst soldering. After printing with ABS, I applied none slip matting to the underneath. The original: Want the file? it's here Quote Link to comment Share on other sites More sharing options...
Simon Chaddock Posted April 1, 2017 Share Posted April 1, 2017 Just an exercise really but I wondered if it was possible to print a moving single cylinder engine. Based loosely on a Mills 75 but slightly bigger at 1cc. And can be spun round - hence the printed flywheel. Not really a practical proposition as it took quite a bit of work with needle files to get it to move freely. Quote Link to comment Share on other sites More sharing options...
Simon Chaddock Posted April 10, 2017 Share Posted April 10, 2017 Having printed an engine that goes round I wondered if it would be possible to make one that actually works - on compressed air. 24 mm bore and stroke (about 10 cc) but double acting with piston valves. Made up of 21 printed pieces that are super glued together. Note the substantial external balance weight to compensate for the weight of the piston and connecting rod. To get it free running enough it leaks quite a bit but it does run - just! It takes lots of puff! Quote Link to comment Share on other sites More sharing options...

Ian Jones Posted April 16, 2017 Author Share Posted April 16, 2017 Geoff D, Nice stacks! I'm sure they will do your mossy proud. Tony B, Spoteed your front end of fuselage build, you're really getting into it aren't you? Must confess I haven't worked out what your latest is yet though.

Trevor Rushton Posted April 16, 2017 Share Posted April 16, 2017 Tony, I like the look of that wheel; I have drawn up something similar for my Avia using Fusion 360, however I got stuck on drawing the spoke holes on the inside of the rim and I have not progressed it. What diameter are you making? I need about 90mm. Trevor Quote Link to comment Share on other sites More sharing options...

Tony Bennett Posted April 16, 2017 Share Posted April 16, 2017 Trevor. this one is 50mm diameter as a test bed before i print the big 120mm ones for my biplane. this is the mk2 version as the mk1 had the rim holes far too small. yes i had to put each hole in individually and it took ages to do the 72 of them.

Delta Foxtrot Posted April 16, 2017 Share Posted April 16, 2017 Same here Tony, I am also new to CAD. I just thought to mention this sort of capability in case it proves useful to you in the future. Quote Link to comment Share on other sites More sharing options...
Ken Lighten Posted April 18, 2017 Share Posted April 18, 2017 I saw the wire holder that Ian Jones had printed and thought that it looked a relatively simple thing to have a go at designing with Fusion 360, so, using the principles in BobW guide in 'Fusion 360 for modellers' thread, I had a go! It works too! Quite pleased with myself! Ken Quote Link to comment Share on other sites More sharing options...
