An implantable medical device is disclosed comprising a thermoplastic composite body having anterior, first lateral, second lateral, posterior, superior, and inferior surfaces, and at least one dense portion and at least one porous portion which are integrally formed. The at least one dense portion is formed of a first thermoplastic polymer matrix that is essentially non-porous, and which is continuous through a thickness dimension from the superior surface to the inferior surface. The at least one porous portion is formed of a porous thermoplastic polymer scaffold having a second thermoplastic polymer matrix which is continuous through the thickness dimension. A method for forming the thermoplastic composite body is disclosed comprising disposing a first powder mixture in a first portion of a mold, disposing a second powder mixture in a second portion of the mold, simultaneously molding the first powder mixture and the second powder mixture, and leaching porogen.
Use of additive manufacturing processes in the manufacture of custom wearable and/or implantable medical devices
A method for manufacturing a custom wearable and/or implantable medical device, such as an orthosis (e.g., an ankle brace, etc.), a prosthesis or the like, includes use of scanning processes. A digital model of a surface may be applied to a digital device model to define a custom digital device model. The digital model and, thus, the custom digital device model may include one or more standard features. The custom digital device model may be used with an automated manufacturing process to make some or all of the custom wearable and/or implantable medical device. In some embodiments, additive manufacturing processes may be used to form a portion or all of the custom wearable and/or implantable medical device.

Methods of making articles with a 3D printer using biomaterials that retain physical properties and biological activity are discussed. Methods can include providing a crosslinkable material and a biomaterial to a 3D printer, and crosslinking the materials to form an implant. Biomaterials can include, among other things, bone, or tissue.
Apparatus for manufacturing printout having cross-sectional pattern
The present invention is a printing device using multiple inks and a printing method using thereof, and more specifically, relates to a three-dimensional printing method of a printed product with a cross-sectional pattern comprising a step of providing different inks into each partitioned spaces and applying the same pressure condition to the inks retained in the ink-receiving part, thereby extruding the inks into a single extruding port to prepare and print an extruded ink product, using the printing device comprising an ink extruding member comprising an ink-receiving part receiving the multiple inks in each partitioned space, and an ink-extruding part equipped with a single passage in which the multiple inks received in the ink-receiving part are passed together.
Printable compositions including polymeric and polymerizable components, articles, and methods of making articles therefrom
The present disclosure provides a printable composition. The printable composition includes a polymer, a polymerizable component, a temporary solvent, a photoinitiator, and optionally an inhibitor. The present disclosure also provides an article including an integral blend of a thermoset polymer and a second polymer different from the thermoset polymer. Further, the present disclosure provides a method of making an article. The method includes (i) providing a printable composition; (ii) selectively curing the printable composition to form a gelled article; and (iii) removing at least a portion of the temporary solvent from the gelled article. The method may optionally include (iv) curing unpolymerized polymerizable component remaining before or after step (iii). Also, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying a plurality of layers of an article, the article including: an integral blend of 8 to 50 wt. %, inclusive, of a thermoset polymer and 30 to 90 wt. %, inclusive, of a second polymer different from the thermoset polymer, wherein the weight percent is based on the total weight of the article; and generating, with the manufacturing device by an additive manufacturing process, the article based on the digital object. A system is provided, including a display that displays a 3D model of an article; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of an article.
Modular fabrication systems and methods
The present invention relates to an article fabrication system having a plurality of material deposition tools containing one or more materials useful in fabricating the article, and a material deposition device having a tool interface for receiving one of the material deposition tools.
