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.

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.

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.

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
