The static remover is electrically grounded and contacts the dunnage to thereby remove static buildup from the material.

A non-durable flexible container can include a first film wall including a first portion comprising at least one first structural support member defined in the first film wall, and a second portion that is free of a structural support member. The container can further include a second film wall including at least one second structural support member defined in the second film wall, wherein at least a portion of the first structural support member is adjacent to at least a portion of the second structural support member to define a seam region, and a side of the seam region defines an edge of the non-durable flexible container. The container can also include a closed produce volume defined between first and second film walls; and a seam projecting outwardly from the seam region at an intersection of the first and second film walls.

In manufacturing an electrothermal heater mat, there is provided a preform which comprises a laminated stack of dielectric layers which are made of thermoplastic material and include a central layer or group of layers which include(s) reinforcement and first and second outer groups of layers which do not include reinforcement. The preform includes a heater element and the preform has a first configuration. The preform is then heated to a temperature (e.g. 180° C.) between the glass-transition temperature of the thermoplastic material and the melting point of the thermoplastic material, and the heated preform is formed into a second configuration which is different to the first configuration so as to produce the heater mat.

In order to provide a composite object that can be produced at high quality and low cost using a 3D printer, a composite object includes: a first object obtained by assembling one or at least two assemblable toy blocks; and a second object constituted by one or at least two parts produced through 3D printing, and configured to be attached to the first object so as to cover at least a portion except for part of a surface thereof. Accordingly, it is possible to produce an object at high quality and low cost using a 3D printer.

Certain examples relate to a material management station for use in an additive manufacturing process. In these examples a metering system is applied to measure the amount of build material transported into the material management station from refillable containers. Data describing the metered amount of build material is communicated over a data communication network and remotely compared to an allowance of usage stored in an administration system. Control messages are communicated to the material management station preventing or allowing further use of the build material in line with the allowance usage.

A stereolithography apparatus comprises a build platform (8) connected to a movable frame (11) via a ball joint (12). The ball joint (12) permits a limited range of movement of the build platform in all directions. A locking mechanism (13) is configured to lock the ball joint (12) stationary for calibration of the orientation angle of the build platform (8) in relation to the exposure arrangement (6), so that the lower surface (9) of the build platform is parallel with the second upper surface (7) of the exposure arrangement (6). The ball joint (12) comprises a ball member (14) attached to the build platform (8) and a socket member (16; 16-1, 16-2) connected to the frame (11). A vertical guide (18) is arranged in the frame (11). The socket member (16) is arranged movable vertically inside and along the guide (18) to permit a limited vertical movement of the socket member (16) in relation to the frame (11). The locking mechanism (13) is configured to lock also the socket member (16; 16-1, 16-2) stationary for calibration of the vertical position of the build platform to determine a zero level of the build platform (8) in relation to the second upper surface (7) of the exposure arrangement (6).

In one aspect, the present disclosure provides a nozzle for 3-D printing. The nozzle may include a first nozzle tip defining a first outlet, where the first nozzle tip includes a first channel extending therethrough. The nozzle may further include a second nozzle tip defining a second outlet, where the second nozzle tip includes a second channel extending therethrough, and where the first channel surrounds the second outlet. The second nozzle tip may be retracted longitudinally with respect to the first nozzle tip such that the second outlet of the second nozzle tip is located in the first channel.
