Question

fff: post-processing
use the information below to answer the questions.
cold welding
when working with abs, cold welding is a process commonly used to join parts together. this can be accomplished using acetone.
vapor smoothing
another process commonly used on abs prints is called vapor smoothing. this process also involves acetone but uses the vapor to smooth the outer layer of the print and create a glossy, polished surface.
priming and painting
a process that is frequently used for many different materials involves primer and paint coatings. if there are any irregularities, use automotive epoxy to fill in the holes and then use sandpaper to smooth the surface.
epoxy coating
one process used in fff is to coat a project in epoxy. this can help smooth the surface of a project and add more overall strength to the form.
metal plating
metal plating is a process that creates a metallic finish on a form. the first step is to coat the form in a conductive metal. once the paint has dried, leads are attached to the form and it is placed in a vat of electroplating liquid with a low applied voltage
what can covering a project in epoxy do for that project?
add more strength to the project
add magnetism to the project
repel water from the project

Explanation:

The text under "Epoxy Coating" clearly states that coating a project in epoxy helps smooth the surface and add more overall strength to the form.

Answer:

add more strength to the project
