Abstract: A novel technology to create 3D-printed objects that are extremely temperature resistant, mechanically robust, ultra-low-wear, and exhibit self-healing behavior. The material can be manufactured in a wide variety of process conditions and even used as a high-strength adhesive, enabling hybrid fabrication strategies. The gel precursor for this material is formed from two solids that react to create a high-performance polymer when heated. Unlike similar materials, these are solid at room temperature and form a printable gel when dissolved in a solvent. Addition of a secondary solvent to this gel modifies the solubility and creates a super-saturated fluid with tunable rheology. Once the gel material has been printed, it is allowed to dry via forced convection. This removes the solvent and leaves only the uncured polymer precursors. After the majority of the solvent has been removed, the material is heated to its cure temperature, at which point it melts, cures, and re-hardens.

Abstract: A novel Aromatic Thermosetting Copolyester (ATSP) fully dense sheets can be processed by recycling the foam structure with unique combination of properties including mechanical strength and high temperature performance (compared to PEEK) to help improve part functionality, gain long-term reliability and cost savings. ATSP machinable plates can be used in valves, fittings, bearing, bushing, seals, aerospace parts and pump components.
Abstract: A novel Aromatic Thermosetting Copolyester (ATSP) can be processed into highly effective wear resistant coatings by blending with polytetrafluorethylene (PTFE) and other additives. Surface treatments/coatings are key to improving wear performance and durability in a wide array of applications. The problems associated with use of liquid lubricants, hard/soft coatings are well known but only modest progress has been achieved due to lack of research on new material systems. These coatings were fabricated and tested as highly effective wear resistant coatings by blending ATSP with PTFE and other tribologically beneficial additives. The main advantages of these polymeric-based coatings are their relatively low cost and simple substrate surface conditioning (i.e., no need for expensive surface preparation before coating).
