The invention pertains to a method for manufacturing a three-dimensional object with an additive manufacturing system, such as an extrusion-based additive manufacturing system, a selective laser sintering system, and/or an electrophotography-based additive manufacturing system, comprising providing a support material comprising more than 50% wt. of a semi-crystalline polyamide [polyamide (A)] having a melting point, as determined according to ASTM D3418, of at least 250° C. and possessing a water absorption at saturation, by immersion in water at 23° C., of at least 2% wt.

Method for manufacturing a three-dimensional object

A method for manufacturing a three-dimensional (3D) object with an additive manufacturing system, comprising a step consisting in printing layers of the 3D object from the part material comprising a polymeric component comprising, based on the total weight of the polymeric component:

The present disclosure relates to method of making three-dimensional (3D) objects using an additive manufacturing system wherein the part material comprises a polymeric component comprising at least one poly(ether ether ketone) polymer (PEEK) having a weight average molecular weight (Mw) ranging from 75,000 to 100,000 g/mol (as determined by GPC), for example in the form of filaments or spherical particles, for use in additive manufacturing systems to print 3D objects.

Method of making a three-dimensional object using a poly(ether ether ketone) polymeric component

The present invention relates to (co)polyamides comprising at least 60 mol. % of recurring units of formula (I): (I). The present invention also relates to polymer compositions comprising such (co)polyamides, as well as articles comprising the same and methods of using said articles in high temperature applications requiring sufficient swelling or deformation upon exposure to moisture, such as for example oil and gas extraction processes (e.g. fracturing balls), or as support materials used to print three-dimensional (3D) parts. 

(Co)polyamides obtainable from 1,4-cyclohexanedicarboxylic acid and a diamine of formula HN-(CH)-O-(CH)-O-(CH)-NH

The invention relates to polyamide composition comprising at least one polyamide featuring a melting temperature (Tm), at least one metal oxide selected from magnesium oxide, zinc oxide and calcium oxide, and titanium dioxide, said composition featuring an intrinsic melt viscosity of below 800 Pa&#xb7;s as measured according to ASTM D3835-08 at a moisture content as measured according to ASTM D6869-03 in the range of 150-500 ppm at a shear rate of 400 sand at a temperature ranging from [(Tm max)+10&#xb0; C.] to [(Tm max)+20&#xb0; C.] where (Tm max) is the highest of all melting temperatures (Tm). Invented compositions feature high reflectivity in the molded part with high retention of whiteness and reflectivity after heat aging. This unique combination of properties makes the compositions according to the invention most suitable for LED applications.

Polyamide compositions for LED applications

The present invention relates to stain- or dye-resistant articles comprising a polymer composition comprising at least one semi-aromatic polyamide comprising recurring units resulting from the condensation of terephthalic acid and at least one aliphatic diamine comprising more than 8 carbon atoms, at least one filler and from 0.1 to 35 wt. % of at least one white pigment, based on the total weight of the composition.

Stain-resistant articles

Polyamide having a melting point between 330&#xb0; C. and 370&#xb0; C., said polyamide comprising:

High melting point polyamide
