Described are a mold and molding process for manufacturing devices and containers that are scalable, modular, and lockable laterally and vertically with other like devices or containers. The mold is formed with a cup mold and top end mold sections specially designed to allow for molding and demolding a container with an undercut. The cup mold includes, on a vertical wall, one or more undercuts. Multiple undercuts may further form tongues with undercuts each of which forms a groove with undercuts on the molded article, and/or one or more grooves with undercuts each of which form a tongue with undercuts in the molded article. Molding and Demolding of the article with undercuts is further enabled by utilizing an improved method of molding said article with an undercut, and demolding said article from the mold once it is molded, by improvements to each stage of the molding process, including the preform stage, the conditioning station stage, the blow stage and the release stage.

Techniques for evaluating support for an object to be fabricated via an additive fabrication device are provided. In some embodiments, a three-dimensional representation of the object is obtained and a plurality of voxels corresponding to the representation of the object is generated. A first supportedness value may be assigned to a first voxel of the plurality of voxels based on an amount of support provided by a support structure to the first voxel, and a second supportedness value determined for a second voxel of the plurality of voxels, wherein the second voxel neighbors the first voxel, and wherein the second supportedness value is determined based on the first supportedness value of the first voxel and a weight value representing a transmission rate of supportedness through voxels of the plurality of voxels.

A core mould element can be mounted between first and second mould parts. The first and second mould parts and the core mould element can be mounted between first and second thermal platens. The thermal platens can have generally planar faces for mounting in a press, for maintaining a desired pressure within the mould assembly. The thermal platens can provide for heating and cooling the mould assembly, and each can include a central portion and end portions, with thermal breaks between the central portion and the end portions. Bores can extend through the central and end portions, for receiving heating elements and pipes for cooling fluid. The end portions can include bores for a cooling fluid for cooling the end portions.

The present disclosure provides a diaphragm forming mold, including includes a mold body, the mold body includes forming regions and material removing regions connected with the forming regions, diaphragm bodies are formed in the forming regions, and at least one corrugated structure is formed in the material removing regions. The present disclosure may effectively improve a contraction effect of a material of diaphragm disposed in the material removing regions, thereby improving an overall contraction effect of the material of the diaphragm, reducing an amount of the compensation of the diaphragm forming mold for a size of the diaphragm, so that a flatness of the diaphragm after being molded is better.
