example

[0254] The present invention will now be described in more detail with reference to the following examples, the purpose of which is illustrative only and not intended to limit the scope of the invention.

[0255] starting material

[0256] Filaments were prepared using the following polymers:

[0257] boron nitride, S1-SF, with a D50 particle size of 2.5 μm, commercially available from 3M Technical Ceramics, formerly ESK Ceramics Gmbh & Co KG (CAS# 10043-11-5)

[0258] carbon fiber, C30 S006 APS, commercially available from SGL TECHNIC Ltd

[0259] talc, Vapor talc, with a particle size of 1.6 to 2.8 μm, commercially available from Lintech International

[0260] stabilizer: Powder (CAS#119345-01-6) supplied by Clariant Corporation

[0261] PEEK #1: Poly(ether ether ketone) (PEEK) with a Mw of 71,300 g / mol prepared according to the following process:

[0262] In a 500 ml 4-neck reaction flask (equipped with a stirrer, N2 inlet tube, Claisen adapter with a thermocoup...

example 3

[0297] The FFF part of Example 3 shows a significantly higher modulus of elasticity than the FFF part of Example 2c without BN. With BN, the elongation at break of 13% is lower, but the value is still in the ductile range (yield observed at about 5.3% elongation at yield).

example 1

[0298] Example 1c shows a complete loss of ductility in an FFF part containing 10 wt.% carbon fiber. While the presence of carbon fibers gives high modulus and strength, the results show that the use of BN is expected to lead to better printability, ductility, modulus and colorability (parts are not black and can be obtained by using pigments or dyes) while coloring) combined advantages.

[0299] The composition of Example 3 has melt rheology and solidification kinetics that are particularly suitable for the FFF process. The compositions of Examples 1c and 2c showed a small decrease in density in the FFF process. Furthermore, the fracture surfaces of the impact bars obtained with the composition of example 3 showed no evidence of porosity compared to other compositions containing talc or carbon fibers.

[0300] Boron nitride is a flake micron-sized mineral. Talc is similar in geometry and size. However, the FFF part of Example 5c using talc has poor mechanical propertie...
