Re: ABS print settings

Hey OncologyEngineer, I print a lot of ABS with the stock .4mm nozzle. It's useful to change settings here and there. I typically use eSun black ABS though there's nothing magic about it. On my machine, I raise the nozzle temp all the way to 245 and the bed to 108. With the bed temp that high, you w...

Re: Mortal Kombat Scorpion Mask & Amor

The propmaker's approach to this kind of thing would be to print it in something like PLA, make a mold, and cast it (the strap-like bits might get sewn and distressed). I don't know where you're located, but in Los Angeles, Reynold's Advanced Materials could talk you through molding/demolding and re...

Re: Mortal Kombat Scorpion Mask & Amor

Really nice work!

Curious -- I do a lot of reverse engineering these days but it's usually in an engineering context. When you're designing things like the mask, what's your process for fitting it to the scanned data? Do you just model it close? Do you snap it to the scanned geometry?

Re: Infill in check fixtures

Really depends on the job. I tend to use the thickest possible layers and 25-50 percent infill when printing ABS for fixturing.

If it's something that's going to get used once, I might go as low as 10% to speed things along as much as possible.

Re: Print keeps shifting

I know it seems implausible and is probably not the case here. Just to explain a little further, I had a large print which failed in the way pictured (shift of some kind). At some point during the print process, the print head mashed the heck out of the limit switch. Every print after that was showi...

Re: Print keeps shifting

You don't have to, but you will get better results as a general rule. I only check filament when it's acting up. I've had similar problems to yours once or twice. The first time, it was a nozzle strike. The other times, my limit switch was mashed (I know this seems improbable). Poke your head in the...

Re: Filament Brand suggestions

Warpage is my issue. I gave up on the Buildtak and just installed Gizmo Dorks PEI sheet. Seems to be sticking a lot better now. Does the bed temp increase of 8 make big difference?[/quote] I use ABS juice on glass, but yes, it makes a big difference for me. If the bed is at 100, prints will peel up ...

Re: Filament Brand suggestions

My go-to ABS is eSun black, I've printed many hundreds of objects with it. The only change I make to the stock ABS profile is changing the nozzle temp to 245 and the bed to 108. What sort of problems are you having?

Re: Filament Brand suggestions

IC3D fans, have you had any luck with their black filament? I print a lot of engineering parts in black and I'm willing to pay for quality.

Also, a bit OT, has anyone tried any of the low-warp ABS formulations? They seem to be really expensive and kind of hard to source.

Re: Rotating Ball-Screw nuts

It seems like it would also be possible to design a printed flex-joint that allows translation but not rotation. This is super-crude, but something like this (with one additional degree of freedom):

Impressive prints. Did you print the bolt and nut just to try that out? I always try to use the real fasteners when possible.

Re: Easy printing, high-temp material

I've used MR16 halogen bulbs on a dimmer to keep the print warm and prevent warp. On the Makerbot this was super easy because there's a huge area around the print.

I went looking for low-warp ABS and it sure seems expensive. I would definitely be interested in US-based low-warp ABS around $30/Kg.
