Question 1

Can I paint or plate resin parts?

Accepted Answer

Yes, after thorough cleaning and light sanding. Use a primer compatible with photopolymer resins; some solvents can craze the surface.

Question 2

Does nylon need to be dried before printing?

Accepted Answer

For SLS/MJF the supplier handles powder conditioning. For FDM nylon you must dry filament at 70–80 °C; otherwise steam bubbles ruin layer strength.

Question 3

Is resin stronger than PLA?

Accepted Answer

Some engineering resins are stronger than PLA in tension, but most are more brittle. Nylon is tougher than both in real-world impact and fatigue.

Question 4

Which is better for waterproof parts?

Accepted Answer

Resin prints are naturally more water-resistant if post-cured properly. Nylon absorbs water, so sealed or coated nylon is usually needed for wet environments.

Question 5

How do I choose between standard and high-temp resin?

Accepted Answer

High-temp resins are for molds, under-hood prototypes, or parts that see sustained heat. They cost more and are more brittle; use them only when temperature is the deciding factor.
