hey guys (and gals). So my Printrbot simple metal arrived and I assembled it with no problem. I printed a few pieces and was amazed by the quality ( mostly objects with little to none detail and parts for the printer itself). I wanted to print a Lego technic piece as that is one of my passions and found the their was a lot of bridging problems within the holes and the pins snapped easily. Any ideas on how to correct the bridging problems.
If you are printing circular holes it is best to lay it down and print it with the holes facing upwards. That way you really don’t have any bridging
BTW, Lego had absurd tolerance requirements to work. You will have issues getting things work consistently.
also does anyone have ideas on how to print higher detail. I want to start printing Warhammer 40K pieces but not sure it can handle the detail
@Branden_Coates ya I was thinking of that but thought I would have too much trouble with the little stilts going lengthwise on the pins
For detail, use a .1 mm layer height, slow the print down to 30 or 20 and put extra fans on it. You may be surprised at what it can do. Smaller nozzles may help if you are really going for perfection. All the variables do get harder with smaller nozzles but it’s possible to do incredibly small detailed parts once you find the magic settings.
@Brook_Drumm Thanks (total noob here but) can you just change the nozzle for any extruder or do you have to change the entire extruder.
If you have the ceramic ubis all you have to do is take the heat sleeve off and use two crescent wrenches to twist off the nozzle. It must be heated up though. But the short answer is no, all you need to switch out is the nozzle. Check http://printrbot.com for different nozzle sizes.
@Griffin_Paquette thanks
