Yes, Glass-Filled PA12 is significantly stronger and stiffer than regular PA12 due to the addition of 10–60% glass fibers. These fibers reinforce the polymer matrix, improving tensile strength, rigidity, and dimensional stability. 

Compared to PA6 or PA66, Glass-Filled PA12 has much lower moisture absorption. This means it maintains dimensional accuracy, consistent mechanical properties, and stable performance even in humid environments. The low moisture uptake is one reason it is widely used in aerospace, automotive, and electronics applications. 

Glass-Filled PA12 performs very well under elevated temperatures and offers excellent resistance to fuels, oils, greases, mild acids, and industrial chemicals. Its reinforcement improves heat deflection temperature and structural strength, making it suitable for automotive engine bay parts, machinery housings, and chemical-contact components. 

Yes, PA12 GF is compatible with both CNC machining and additive manufacturing processes such as MJF and SLS. However, its abrasive nature requires specialized tooling during machining to prevent excessive wear. In 3D printing, PA12 GF provides high stiffness and low warpage. 

Glass fibers can influence the surface appearance and feel of PA12 GF parts. Machined parts may exhibit visible fiber texture, while 3D-printed parts have a slightly matte, grainy finish. XC Machining offers several post-processing solutions, such as vapor smoothing, media tumbling, and coating.
