Monotonic and cyclic compressive performance of self-monitoring MWCNT/PA12 cellular composites manufactured by selective laser sintering

Composites Part C: Open Access
Herein, we experimentally investigate the mechanical and piezoresistive properties of selectively laser-sintered cellular composites under monotonic and cyclic compressive loading. Hexagonal honeycomb structures (HHSs) with relative densities of 20 %, 30

Room-Temperature Material Recycling/Upcycling of Polyamide Waste Enabled by Cosolvent-Tunable Dissolution Kinetics. [PDF]

Angew Chem Int Ed Engl
Physical recycling of polyamides (PAs) requires high temperatures due to solvent resistance. Rapid dissolution of PAs in formic acid (FA) using a cosolvent strategy enables room‐temperature recycling and upcycling for utilization of high‐value resources.

Influence of DMAc on Rheological and Thermal Behaviors of PA12 for Laser Powder Processability

Journal of Applied Polymer Science, Volume 142, Issue 31, August 15, 2025.
ABSTRACT The study investigated the influence of dimethylacetamide (DMAc) on the rheological behavior of molten polyamide 12 (PA12), its effects on powder morphology, and thermal properties to establish its processability for additive manufacturing. Both the storage modulus (G′) and loss modulus (G″) exhibited nonlinear viscoelastic behavior due to ...

Recycling of PA12 powder for selective laser sintering [PDF]

AIP Conference Proceedings, 2020
In selective laser sintering (SLS) predominantly polyamide 12 powder (PA12) is used. Often, after the sintering process approximately 70 % of powder, which has not been sintered, remains. The flow properties of this used powder have been affected because of the thermal stress during the sintering process.
