An additive-manufacturing resin vat system can include a resin vat, a flexible plastic film, a transparent support window, a transparent conductive coating, a support tray, and a set of metal contacts. The resin vat can carry a resin-print material mixture. The flexible plastic film can mechanically seal to a bottom of the resin vat. The transparent support window can support the flexible plastic film. The transparent conductive coating can be formed on at least one side of the transparent support window. The support tray can define an outer tray portion and an open tray interior, the outer tray portion carrying the transparent support window. The metal contacts can be carried by the outer tray portion and configured to electrically couple with the transparent conductive coating. The transparent conductive coating is configured to generate heat upon receiving an electrical current via the metal contacts.

Three-dimensional printer resin vat with heated support window

A photopolymer development resin base is available for use with additive manufacturing units (for example, various three-dimensional printers) to create three-dimensional (3D) printed structures. In some embodiments, the resin formula can include a monomer, oligomer, diluent, photo initiator, deflocculents, wetting agents, and dispersants, with a limit on any photo-blockers, if present at all. The photopolymer development resin base functions as a binder precursor material with the capacity to accept solid powders or liquids for UV printing, which is not configured to print 'as is.'

Photopolymer development resin base for use with three-dimensional printer

A three-dimensional printed structure can include a photocurable resin, a sinterable material, and a plurality of elongated particles. The elongated particles are distributed within the printed structure. The elongated particles are shaped and distributed to promote porosity control (e.g., improved densification) within the structure.
