Over the next few weeks we will explore “The science of…” different issues related to 3D printing. This week we are interviewing Polymer Technology lecturer Colin Hindle about ABS filament!
Keep an eye out for solutions to the problems discussed in a future post: http://bit.ly/1l5GCj6
Way to go dude!!!
On that note, does anyone have any particular questions they would like to ask about ABS? Perhaps you are facing an issue with the material? We will attempt to answer in a follow up!
The most prominent failure mode is warping or delamination of the layers. There are so many different methods that people use try to use to tackle the problem. From “mouse ears” to brim, glue, floorwax, hairspray, enclosures, heated beds, rafts, egtc. My own solution was to print slow… Like really slow, 10mm/sec.
So the question is, which method is the best, or what combination of methods.
Thanks @Stephanie_A ! We will respond to your question soon.
I find that ABS is really particular to it’s extrusion rate. Too thin and it starts to peel back on overhangs. Too much and it looks terrible. Printing slower does help @Stephanie_A but that more negates the larger issues and makes printing “big” objects with ABS very frustrating.
@3dprintworks I’m curious to know if ABS adheres better per layer (not necessarily just bed) at the higher end of the temperature spectrum. I tend to run at 240-250 and get great results, 210-220 for my PLA with similar results.
Also, what filament diameter is ideal for ABS (if any?) My 3mm clogs up much more frequently than 1.75, but only with ABS. I found the larger diameter filament may “choke out” at higher temps but that’s only a hunch.
Letting people know how and why all ABS filament is not the same, and what properties make for a good printing resin. E.g MFR, Inherent viscosity etc
@Stephanie_A @Ben_Van_Den_Broeck @Sanjay_Mortimer we have tried to answer your questions here, hope this helps: http://bit.ly/1q4rUc7
