Best Adhesion?

[Alibert]

Also:

6) ABS can be etched to enhance adhesion when (vapor deposition) galvanizing or painting. This etching process makes the surface micro-porous, hence the better physical adhesion.

I think that people lean on PLA because it's easy not because it's a better material.

Mostly because you really need an enclosed (and preferably heated) printer if you want to print bigger parts. A lot of printers do not have that. You can still print with ABS, but only smaller parts to prevent warping and cracking. Also the smell when printing is nicer and it is touted as being biodegradable.

I am now adding a regualed ceramic heater to a second printer. With that I can heat up the interior to a consistent value (using 50 to 60 C at the moment, will gradually increase to 70-80 C in the near future). When the ambient temperature approaches the glass transition temperature, you negate virtually all warping with any polymer. I might write a post on that topic when I have more time....
