Identifing material used for part.  

RE: Identifing material used for part.

Perhaps add the identifying letters in plain text, proud or incised, on a non-obvious part of the print, similar to how Prusa "brands" the Revision Number of some parts? Yes, you'd have to have a separate file for each material, but that should be a relatively simple matter.

Does anyone have a procedure for marking parts? I though perhaps X's with a chisel point soldering iron ie X=PETG, XX=ABS, XXX=ASA etc. Unfortunately my hand just isn't that steady.

Any suggestions.

 

I do not but like this methodology.  Easier to read a number of X's

Another option could be small half spheres as a cutout.

How about this?

More legible?

I woul say it is.  

RE: Identifing material used for part.

It doesn't help to include the id in CAD (unless you have the patients to general 3 or 4 STL's with different text).

So I went back to the github conversation and found the answer. You can load any STL as a modifier (right click, Add modifier, Load ...) so ALL I have to do is generate a part with the desired text and emboss in PrusaSlicer. This may take a while as CAD skills pretty poor.

PrusaSlicer really is getting pretty good although Cura still has a couple of tricks eg. tree supports, fuzzy skin.

This is basically what I do in the CAD program; I have several "branding" phrases saved that I can just copy/paste them where I want them, then export to STL. Sure you can bring them into PruserSlicer as modifiers, but then orienting them, sizing and getting them "attached" to the desired surface can be pretty tedious. And if the desired surface is curved or non-orthogonal, forget it. Much easier done in CAD IMHO, YMMV.

RE: Identifing material used for part.

Yes I'm sure it's easier in CAD and positioning modifiers can be a pain but in this case I don't think I would remember to load different STL's.

One more complexity of making a modifier "punch" is that the text has to be mirrored.

How about that: https://en.wikipedia.org/wiki/Recycling_codes#List_of_resin_identification_codes_(RIC)_and_codes_defined_by_the_European_Commission ???

RE: Identifing material used for part.

Unless the various codes/symbols are already downloadable in your preferred CAD format, you'll have to model them up yourself any, in which case you might as well use the actual abbreviations (ABS, PETG, PLA, etc.) instead of the code numbers and what they refer to, that I'd rather not clutter up my already addled brain with.

Well the are international use. So everyone know what does the mean here.

Dunno about you, but I'd rather not clutter up my already addled brain with information like that.

RE: Identifing material used for part.

Sorry, dunno how the duplicate got sent, maybe an admin can remove.

So I'm guessing there at least ten "exotic" plastic filament formulations that "we" use every day, but are relatively unknown, or at least not common enough to have their own International recycling code(s). Roll your own.
