A filament for use in forming a support structure in fused filament fabrication, the filament comprising an amorphous, thermoplastic resin further comprising Bisphenol Isophorone carbonate units and Bisphenol A carbonate units, wherein the Bisphenol Isophorone carbonate units are 30 to 50 mole percent of the total of Bisphenol A carbonate units and Bisphenol Isophorone carbonate units in the resin, and wherein the resin has a glass transition temperature from 165&#xb0; C. to 200&#xb0; C. The composition used to form the support filament exhibits a desirable combination of filament formability, printability, lack of significant oozing from the printer nozzle, and good ease of mechanical separation from the build material at room temperature after printing.

3D printing heat resistant support material

The disclosure is directed to polymer compositions comprising a matrix polymer component comprising a crystalline or semi-crystalline polymer; and a fibrillated fluoropolymer, a fibrillated fluoropolymer encapsulated by an encapsulating polymer, or a combination thereof. Methods of preparing and using these polymer compositions, as well as articles comprising the polymer compositions, as also described.

Fibrillated polymer compositions and methods of their manufacture

A polyetherimide composition includes specific amounts of a polyetherimide, a block polyestercarbonate, a block poly-carbonate-polysiloxane, and a core-shell impact modifier in which the core includes a polysiloxane and the shell includes a poly(alkyl (meth)acrylate). Relative to a corresponding composition lacking the core-shell impact modifier, the polyetherimide composition exhibits increased impact strength while substantially retaining flame retardancy. Also described are associated articles, including articles formed by additive manufacturing, and a method of additive manufacturing.

Polyetherimide composition and associated article and additive manufacturing method

Disclosed herein are methods that includes using a water-degradable (e.g., autoclavable) support material together with a high-heat build material (e.g., polyetherimide or PEI). When the support material is autoclaved for a period of time, the support material becomes brittle and then disintegrates into powder and therefore can be removed from the model or build material, leaving behind a part formed from the model material that includes features (e.g., cavities, channels, etc.) formerly occupied by the support material.

Sacrificial high heat support materials for additive manufacturing processes

Disclosed is a thin-walled article that can be used for medical applications. The medical article is molded from a thermoplastic composition. The composition comprises a poly(aliphatic ester)-polycarbonate copolymer, a mold release agent, and a gamma radiation stabilizer. The composition exhibits excellent melt flow rate, is amenable to thin wall injection molding, and has good transparency.
