Is there a list of the polymer materials and the advantages/problems of those? I often read PLA is best, but thats hard to find in germany. Which other materials are good to extrude and have low thermal shrinking values? thanks in advance https://reprap.org/forum/read.php?70,43652,43652#msg-43652 Sat, 16 May 2026 14:28:57 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?70,43652,43955#msg-43955 https://reprap.org/forum/read.php?70,43652,43955#msg-43955
I wonder how much heavier a printed quadrotor would be - I mean the carbon fiber is obviously lighter but not having any milled aluminum blocks might balance that out.. this might be worth some investigation once I get a 2nd printer going.]]> theOtherRob Plastic Extruder Working Group Wed, 28 Apr 2010 11:48:32 -0400 https://reprap.org/forum/read.php?70,43652,43945#msg-43945 https://reprap.org/forum/read.php?70,43652,43945#msg-43945 goaran Plastic Extruder Working Group Wed, 28 Apr 2010 10:07:31 -0400 https://reprap.org/forum/read.php?70,43652,43921#msg-43921 https://reprap.org/forum/read.php?70,43652,43921#msg-43921 @Rob: if you want i can send you the source and the schematics of the quadrocopter.

Want to tack it up here:

? It would be very helpful, I've seen a lot of quadcopter interest around here. :)

You can use the example mediawiki code from our example page:

- PLA is bad because it requires finer tuning to extrude well (in my experience)

- ABS is good because it is easier to buy and easier to extrude well for small parts
- ABS is bad because it tends to warp catastrophically on large parts off the build platform unless you use a heated build platform (in which case it is just as nice as PLA and easier to print with!)

I've incorporated a bit of this into the existing ABS and PLA wiki pages.

By the way that is a sweet quadrotor you've got - always wanted one myself but I haven't found the time so far - keep living the dream :)]]> theOtherRob Plastic Extruder Working Group Tue, 27 Apr 2010 13:14:38 -0400 https://reprap.org/forum/read.php?70,43652,43652#msg-43652 https://reprap.org/forum/read.php?70,43652,43652#msg-43652 I often read PLA is best, but thats hard to find in germany.
