First Claim
1. A method of producing polymer articles comprising(i) subjecting a composition to additive processing in an additive processing device containing at least one energy source wherein the composition comprises particles of a first polymer, particles of a second polymer and at least one binder material capable of binding the polymer particles to form a layer in a part of the composition that has been exposed to the energy source of the additive processing device;
- (ii) subjecting at least a part of the composition to exposure of the energy source to form a layer comprising the polymer particles and binder material; and
(iii) repeating step (ii) to form a plurality of layers to create an article; and
wherein the first polymer is selected from polymers having a melting point above of at least 250°
C. or a glass transition temperature (Tg) of greater than 70°
C. and is not a fluoropolymer and wherein the second polymer is a fluoropolymer;
wherein the binder material is polymerizable and capable of binding the polymer particles to form a layer comprising the polymer particles by polymerizing in a part of the composition that has been exposed to the energy source of the additive processing device;
orthe binder material is capable of binding the polymer particles to form a layer comprising the polymer particles in a part of the composition that has been exposed to the energy source of the additive processing device by melting upon exposure to the energy source.
