The technology has been applied with great success across dozens of commodity, engineering, and composite/filled materials. The adaptive nature of the process makes it ideal for materials that are variable in viscosity, such as post-consumer recycle, wide-spec materials, moisture level variation, and certain additives, colorants, and fillers. Results are improved with materials that are prone to warp, sink, or have aesthetic issues such as splay, tiger striping, read through, or “ghosting”. Filled materials, require slightly faster filling, however, surface appearance and warp are improved in most cases. Optical applications can benefit from the lower and more uniform stress concentration provided by the low-constant-pressure process.
