Question

pbf: dimensional accuracy. use the information below to answer the question. the tolerances of direct metal laser sintering are very good. they are the same as material jetting with a size of 0.1 millimeters - just below that of a human hair. once the print is complete, the supports need to be cut off the print bed by the operator. once the user has the piece, they can do any processes to it that they would with any other metal material. materials - stainless - strong, corrosion - resistant and the most cost - effective. - bronze - it is functional but quite expensive. - aluminum - is a good material but expensive. - titanium - is another good material but expensive. in terms of powder bed fusion (pbf), which of the following is true about aluminum? it is not compatible with the process. it is expensive. it is the cheapest material. it has the highest heat resistance.

Explanation:

The text mentions "Aluminum is a good material but expensive" in the context of Powder Bed Fusion (PBF). So we can infer the relevant property of aluminum.

Answer:

It is expensive.
