PLA vs ABS
PLA vs ABS: Filaments for 3D Printing Explained & Compared | All3DP - https://all3dp.com/pla-abs-3d-printer-filaments-compared/

PLA (PolyLactic Acid) is a biopolymer, i.e., a biodegradable plastic. It is made from renewable raw materials such as cornstarch or sugarcane. Aside from 3D printing, it is typically used for packaging material, plastic wrap, plastic cups and plastic water bottles. It is considered to be more ecologically friendly than ABS – after all, it’s made from plants.

ABS (Acrylonitrile-Butadiene Styrene) is an oil-based plastic. It is a tough material that can be used to create robust plastic objects for everyday use, for example in cars, electrical equipment or even in the popular Lego bricks.

Overall, PLA is better suited for 3D printing beginners. ABS is more susceptible to typical 3D printing problems such as warping (i.e., the first layers cool down quicker and shrink, which causes the lower parts of the model to bend up at the edges). Printing ABS requires a bit of experimenting to find out the optimal settings.

Fumes. PLA smells somewhat sweet, like waffles or candy when heated. ABS, when heated, gives off a bad plastic smell. Some people report headaches and nausea from 3D printing. We recommend proper ventilation in enclosed areas.

Smoothing
For ABS use Acetone vapors
 * vitrify

For PLA use Ethyl Acetate
 * 'MEK Substitute' shown in the post is Ethyl Acetate.
 * dip it in dichloromethane or chloroform
 * PLA solvent is dichloromethane, not methyl acetate.

Cement
Put discarded pieces of plastic into the appropriate solvent.

Toxic Emissions

ABS stands for: acrylonitrile butadiene styrene. Why is that important? Styrene is one of those hazardous volatile compounds — it’s toxic and maybe cancer-causing. While the Environmental Protection Agency (EPA) in the United States doesn’t have protections against it, the Department of Heath and Human Services calls styrene “reasonably anticipated to be a human carcinogen.”

Fortunately, PLA (polylactic acid) breaks down into lactic acid — the same chemical that makes you sore after working out — so there’s no threat there.
