A Fully 3D‐Printed Packed Absorption Column: Design, Hydrodynamic Performance, and CO2 Benchmarking

Chemical Engineering &Technology, Volume 49, Issue 7, July 2026.
ABSTRACT Additive manufacturing enables tailored column internals and structured packings that are difficult to fabricate by conventional methods. While significant progress has been made in the development of additively manufactured packings, no study to date presents a fully 3D‐printed absorption column in which both the shell and internals are ...

Effects of Polyamide‐6 Bulk Plasma Treatment on Morphology, Crystallinity and Mechanical Properties of Microfibrillar Composites

Polymer Composites, Volume 47, Issue S2, Page S261-S274, 20 June 2026.
Microfibrillar composite containing highly oriented, plasma‐treated PA6 microfibrils embedded within the polymer matrix. ABSTRACT Plasma treatment is often used to alter chemical surface characteristics of fibers or polymers, improving dispersion of components and interfacial adhesion between incompatible constituents in composites.

Radiation spheroidization as a potential method enabling recycling of polyamide 12 waste from powder bed fusion of polymers

Materials & Design
Thermal aging hinders the use of powder bed fusion (PBF) for large-scale production. Inefficient waste management in PBF requires mixing 30–50 % virgin powder, while only ∼ 10 % becomes final parts.

A Comprehensive Optimization Course of Antimony Tin Oxide Nanofiller Loading in Polyamide 12: Printability, Quality Assessment, and Engineering Response in Additive Manufacturing

Nanomaterials
This study aimed to investigate the potential of antimony-doped tin oxide (ATO) as a reinforcing agent for polyamide 12 (PA12) in 3D printing by examining four mixtures with varying ATO concentrations (2.0 to 8.0 wt.%, with a 2.0 wt.% interval).

Performance of CF/PA12 composite femoral stems

Journal of Materials Science: Materials in Medicine, 2007
This study presents the microstructural and mechanical behavior of the CF/PA12 composite material developed as well as its biomechanical performance when used for the fabrication of femoral stems. The static tests were performed to evaluate the compressive and flexural modulus as well as the ultimate compressive and bending strength.
