Differences between ABS and PLA? Which is best?

[Ama-fessional Molder]

ABS is a polymer whereas PLA is a polyester. Which is better? Depends on the application. Either will do for your needs although ABS will be more shock resistant.

Polyester is a polymer as well. All plastics are polymers. It's just one subcategory.

And continuing on the late to the party trend:

but compared to pla - damn few of them.

There are currently 6,106 results for 'ABS' in the materials database I use, many are base resins with different fillers (glass, minerals, lubricants, etc) and multiple manufacturers are listed which may have the exact same chemical makeup, so I could very conservatively estimate close to a thousand unique additive formulations.

Afterall, the additives define most of your processing parameters.
