According to examples, a three-dimensional (3D) fabrication system may include a controller to identify a feature of an object to be fabricated and based on the identified feature having a size that is smaller than a predefined size, determine a thermal support for the identified feature. The controller may also control fabrication components to form, through application of energy, the determined thermal support from a first set of particles, form an intermediate section adjacent to the formed thermal support from a second set of particles, and form, through application of energy, the feature adjacent to the intermediate section from a third set of particles, in which heat from the thermal support is to reduce a thermal bleed rate of the third set of particles.

In an example, a three-dimensional (3D) printing kit includes a metallic build material composition; a binding agent; and a release agent for patterning a breakable connection. The binding agent includes a first latex binder. The release agent includes a white colorant including a white metal oxide pigment coated with a coating selected from the group consisting of alumina, silica, and combinations thereof; boehmite particles; a second latex binder; and an aqueous vehicle.

A wax layer may be applied to a print bed to promote adhesion and release of a printed part during additive manufacturing. Additive manufacturing methods may comprise: depositing a wax layer comprising one or more waxes upon a print bed of an additive manufacturing apparatus, and forming a printed part upon the print bed through layer-by-layer deposition of a printing material. The printed parts may be released from the print bed once printing is complete, but without damaging the print bed.
