Couple of pics of the Drive Screws for the Bicep/Shoulder and a Wormgear that is printed without “Support Material” that I have been playing around with – done half a dozen test Prints to find the right Setting in Slic3r – the fail ones are there to show the area I wasn’t happy with ,,,,
As you can see the worm gear still needs a bit of work,, the slight Taper at the top was settings error ( printed to slow and to hot)—but its tough as hell ,,,took 40kg of pressure with ease – got the 100% infill dialled in nicely which is Make or Break when it comes to the Strength of the Part,,,,
As you know I print InMoov in ABS, and try to print everything without support.
I print the worm gear and bicep piston parts without support.
I never run fans in my printer to cool down the parts, but I have set an aquarium pump with a tiny tube that travels all the way to the printing head, which then blows precisely an air stream where it’s needed and not every where else. ABS doesn’t like fresh air…
This gives me perfect prints without warping or delaminations.
Ha ,,Ha,, and I thought I was the only one crazy enough to have a Air Pump from a Fish Tank on a Printer (But my son wasn’t impressed that I killed all the fish) – but anyway,,, that was the only way I found to get good Print in ABS too—,, the good thing about using PLA+ is it forces me to design without gluing to be an option which is challenge,,, and I like a good challenge….I haven’t Printed in ABS for about 3yr now ,,,,( but I do miss it sometimes)
