Experimental analysis of failure behaviour of PA12 specimens manufactured by SLS as a function of wall thickness and build direction

Rapid prototyping journal
Purpose This paper aims to investigate and explain the dual fracture behaviour of PA12 specimens sintered by selective laser sintering (SLS) as a function of wall thickness and build direction with a powder mixture 30:70.

Influence of post-processing treatment on the surface roughness of polyamide PA12 samples manufactured using additive methods in the context of the production of orthoses

Proceedings of the Institution of mechanical engineers. Part B, journal of engineering manufacture, 2023
Additive techniques are gaining popularity, primarily due to the emergence of new 3D printing methods, advancements in 3D printers, and the availability of innovative materials.

Reaction injection pultrusion of PA12 composites: process and modelling

Composites Part A: Applied Science and Manufacturing, 2003
The development of a reactive pultrusion process is presented by considering the advantages of an in situ polymerisation of thermoplastic lauryllactam monomers. The specifics of the reaction injection unit, of the fibre-drying oven and of different pultrusion dies are given.

Recovery of residual polyamide (PA12) from polymer powder bed fusion additive manufacturing process through a binder jetting process

Rapid prototyping journal
Purpose This study aims to propose the reuse of PA12 (powder) in another AM process, binder jettiinng, which is less sensitive to the chemical and mechanical degradation of the powder after multiple cycles in the laser system.

Comparative study on the thermal and tribological properties of PA12 and PA11 for coating applications

Journal of Applied Polymer Science
In this study, the performance and potential applicability of polyamide‐12 (PA12) as an alternative to polyamide‐11 (PA11), which is currently used in the coating processes of sliding tools present in cardan shafts, was investigated.

Electrical Properties Investigation in PA12/PANI Composites

Macromolecular Symposia, 2010
AbstractSummary: Volume conducting PA‐12 based composites powders were chemically prepared by in situ polymerization and aniline doping at room temperature. These kinds of polyamide / PANI composites were investigated regarding their electrical properties. Their ac and dc electrical properties measured in the frequency range of 10−2–107 Hz are reported

New perspectives on poly(lauryllactam) PA12: Optimization of process parameters for AROP of ω‐lauryllactam

Journal of Applied Polymer Science
This study focuses on how catalyst concentration, activator concentration, and initial polymerization temperature impact in‐situ anionic ring‐opening polymerization (AROP) of ω‐lauryllactam. Catalyst and activator roles are fulfilled by NaH and toluene‐2,
