Why are FDM printed parts usually stronger than SLA printed parts?
In: 3
Mostly materials. There are a lot of factors but some of it is related to the tensile strength and elongation at break, which is a function of the polymer which is a function of the polymer chains which is a function of the curing mechanism of SLA. A chemist can explain things more technically correct than myself.
There are ABS-like resins, such as those offered by Formlabs.
Essentially, one material is stronger/harder than the other. Not all plastics are made equal.
To delve into the exact material properties and reasons why certain materials are harder than others is a lot deeper of a topic than an eli5 warrants, and a bit out of my depth since I’m not a plastics specialist.
