Abstract: An embodiment of the present disclosure is directed to a method of additive manufacturing. The method comprises: i) forming a first layer, the first layer comprising at least one material chosen from an article material, a support structure material and a fracturable material; ii) forming an additional layer on the first layer, the additional layer comprising at least one material chosen from the article material, the support structure material and the fracturable material; and iii) repeating ii) one or more times to form a three-dimensional build comprising an article and at least one support structure attached to the article at an interface, the interface comprising the fracturable material formed during one or more of i), ii) or iii), the fracturable material being formed by exposing a print material with a gas reactant. A three-dimensional build is also disclosed.

Abstract: A build plate is configured for use in a 3D printer. The build plate comprises a base comprising a base material and one or more vacuum channels. A removable plate is disposed proximate the base so as to be in fluid communication with the vacuum channels.

Abstract: Steel cabinet parts and other steel objects are electrocoated in a cationic resin-containing bath. The steel objects are chromium-coated, free of phosphate and preferably free of chromium oxide. The products are not significantly subject to filiform corrosion, and the process is economically beneficial because throwpower is more easily controlled than in previous processes.

Abstract: A transgenic mouse which contains a predefined, specific and desired alteration in at least one of its two chromosomal alleles of a cellular adhesion gene, such that at least one of these alleles contains a mutation which alters the expression of the allele.
