Expert Solution

Question-1: What are the limits of the material being processed in the Fused Deposition Modeling (FDM), apart from the using Thermoplastic only?

NYLON material is having good mechanical properties. This is the best material to resist the impact loads. This material is having a good resistance for chemical reaction.
PC material is as similar as ABS and strongest of all the materials.
PLA material is easiest for FDM processing. Visual quality for PLA is very high. Though this material having brittleness it is strong enough and having good rigidity. Also it is odorless. But it is not easily glued.
PET material is little softer and safe for food related applications. Easily it can be glued. It is having high resistance to chemicals reaction.
ABS material can withstand for higher toughness & high temperature resistance applications. But during printing some odor will come and it tends to high fume emissions.

Question-2: What are the limits of the equipment being used in the Fused Deposition Modeling (FDM), apart from producing small parts only?

For large parts manufacturing on FDM equipment, the part can be as large as the equipment allows for processing.
Needs to change the build area of the machine for manufacturing the larger parts.
Tolerance range that can be possible to get on FDM equipment for larger parts will varies. Example if the part size is 5" then a tolerance of +/-0.005" is possible to get. But if the part size is more than 5" then a tolerance of +/-0.0015".
Hollow parts can't be possible to produce on FDM equipment,
Breaking of Tabs possible especially for larger parts manufacturing, so tab size should be as large as part size,

Should there be any limits on material that is marketed to appeal in some significant way to minors? If so, who should set those limits, how should they be set, and who should enforce them? Does the threat of an expensive, bankruptcy-inducing suit amount to de facto censorship in the music industry? How does one balance the need to protect minors from potentially disturbing images with freedom of speech and personal expression?
