For those that still want to use ABS, please consider this

Angus (MakersMuse) had a good video on ABS and why you may not want to use it anymore in 2017


Do you agree with Angus?

 

someone else in my corner fightin' the anti-ABS fight.

 

Its a sad reality but the majority of my clients dont want to hear whats better. They want ABS and if I say no...off they go . It wont go anywhere for awhile in my area me thinks (most these clients are commercial, standard person just wants what works)

 

Give-em some material science lessons

Actually commercially it can still make sense (on the basis of cost) but from a maker standpoint ... I don't see it.

 

They dont want a lesson, they want it in ABS and right now lol. Maker point of view im not a huge fan as it only runs great on the zortrax out of all my machines lol

 

Wild guess ... Heat deflection most likely. PET and PETG are not a lot better in that respect.

 

people still use PETG?

 

I still use a lot of PETG, especially since most suppliers have added solid colors to the mix. You just can't print everything in translucent. I am trying to move more toward things like polycarbonate and nylons because I would like the heat resistive properties those types of filaments provide.

 

I would bet that 75% or more is ABS at the shop and the rest is PC or Nylon. Occasionally PLA but that is just for people that want cheap props and the such.

For the machine shop- since we do small batch runs (job shop) I make jigs and the such out of PLA. Volcano and .5 layers makes for some darn fine jaw jigs on the mills Expecially since often the job wont come back, or if it does it will be a long time so when were done, we pitch it

 

Geof, I use PLA to make custom tube bending jigs for my PC case mods. I can get complex angles worked out in CAD so that the tubes fit the first time. Unless I overheat or otherwise crack a tube while bending. Most of my last PC mods have been custom water loops with hardline tubing (PETG).

In order to keep my old 2002 Nissan running I have a few 3D printed pieces under the hood and PETG does not hold up to engine heat. Why I am doing more nylon and polycarbonate.

 

Which PC are you using?

 

Right now I recently built a Ryzen 7 1700 overclocked to 3.925 GHz, Gigabyte Gaming K7 MB, 32GB DDR4-2800 RAM overclocked to 3200, nVidia GTX 1080 Ti, 500GB PCIE m.2 boot drive with Win10 installed, 4GB SATA data drive, 750W Corsair PSU. Custom water loop with two 280 mm radiators, hardlined to CPU and GPU, five maglev case fans. A bunch of RGB lighting in a BeQuiet Dark Base Pro 900 case. 43" 4K monitor.

 

I mean which Polycarbonate All I know about computers is how to turn them on (if I'm lucky lol)

 

I have some eSUN but don't really like it, I am just now investigating what works for others.

 

I've used (I only print PC on my Ultimaker) Ultimaker brand and polymaker PC and PC MAX. Printed solid runs sales on them where the spools are cheap cheap. I stock up. I think his next sale is black friday.
