A stabilization apparatus for reducing vibration of a 3D printer during operation thereof. A stabilization apparatus features a stationary framework having a base seated atop a support surface and spanning a greater two-dimensional footprint than the 3D printer. One or more flexible elongated suspenders each has one end connected to a respective anchor point each defined on the supportive framework at a respective location of elevated relation to an underside of the base. Another end of each suspender is secured either to the 3D printer itself, or to a floating support atop which the 3D printer is placed. The 3D printer is thereby supported in a floating position of suspended relation to the stationary framework of the stabilization apparatus.

A continuous filament additive manufacturing machine for building a part by laying down a continuous mono-filament or composite filament material layer by layer on a tool or substrate. The machine includes a system, such as a robot, operable to move in at least three degrees of freedom, and a placement module coupled to the system and being configured to deposit the continuous filament material. The placement module includes a guide for guiding the material to the part, an ultrasonic compaction device including an ultrasonic driver, an attachment frame and an ultrasonic disk horn coupled to the attachment frame. The ultrasonic driver is coupled to the disk horn and ultrasonically vibrates the horn in a reciprocating manner to melt or flow the material and cause the material to fuse and be compacted to the tool or substrate.

A method includes forming an antimicrobial blend including an antimicrobial additive combined with a polymer, and forming a medical device with the antimicrobial blend, wherein a surface of the medical device exhibits antimicrobial properties.

An endpoint for trusted fabrication, the endpoint including at least one secure controller configured for connection to a wide area network; and at least one untrusted controller configured for local communication, wherein the endpoint is configured for connection to a fabricator and further configured to receive digitally-signed data specifying at least one item for manufacture; verify the digitally-signed data; and direct the fabricator to manufacture the at least one item after verifying the digitally signed data. A method for trusted on-demand manufacturing, the method including receiving, at an endpoint connected to a fabricator, digitally signed data describing at least one item for manufacture; verifying, at the endpoint, the digitally signed data; and manufacturing the at least one item using the digitally signed data after verifying the digitally signed data, wherein the endpoint comprises at least one secure controller and at least one untrusted controller.

A method for printing a three-dimensional optical structure, in particular an ophthalmic lens, wherein the three-dimensional optical structure is built up from layers of printing ink deposited through targeted placement of droplets of printing ink at least partially side by side in consecutive printing steps, wherein a slicing (3) of the three-dimensional structure to be printed is adapted depending on a predefined true layer shape (2) so that during at least one printing step at least one layer is printed depending on the predefined true layer shape (2), wherein the predefined true layer shape (2) comprises the shape and/or volume characteristics of a typical printed layer.
