Answer all questions below and test your knowledge.

1
In the context of polyether ether ketone (PEEK) filament printing, what is the primary functional role of a high-temperature, actively heated chamber that maintains an atmosphere above 120°C?
Question 1
2
A project requires a 3D printed metal part with high toughness and fatigue resistance for a dynamic aerospace component. Which post-processing technique, following a standard de-binding and sintering cycle for a 17-4 PH stainless steel MIM feedstock, is most critical to achieve these mechanical properties?
Question 2
3
When formulating a ceramic-filled photopolymer resin for Digital Light Processing (DLP) to achieve a high-density final ceramic part after pyrolysis, what is a major constraint on the maximum volumetric loading of the ceramic powder?
Question 3
4
The 'enthalpy of fusion' (ΔH_f) of a polymer filament is a critical parameter for predicting what specific aspect of the Fused Filament Fabrication (FFF) process?
Question 4
5
In powder bed fusion (PBF) of a nickel-based superalloy like Inconel 718, the formation of 'columnar grain structures' epitaxially aligned with the build direction is primarily a consequence of what fundamental thermal condition?
Question 5
6
For a continuous carbon fiber reinforced thermoplastic (CCF) filament used in a specialized FFF process, what is the predominant mechanism by which the fiber enhances the composite's stiffness compared to the neat polymer matrix?
Question 6
7
A manufacturer observes consistent delamination (layer separation) when printing large parts with an unfilled, semi-crystalline PETG filament under standard settings. Which material property change, achievable via chemical modification of the polymer, would most directly mitigate this failure mode?
Question 7
