Additive fabrication systems generally use support structures to expand the available range of features and geometries in fabricated objects. For example, when a vertical shelf or cantilever extends from an object, a supplemental support structure may be required to provide a surface for fabrication thereon. This process may become more difficult when, e.g., a part will be subjected to downstream processing steps such as debinding or sintering that impose different design rules. To address these challenges and provide a greater range of flexibility and processing speed, it may be useful in certain circumstances to independently fabricate the object and support structures, and then assemble these structures into a composite item for debinding and sintering. This approach also advantageously facilitates various techniques for spraying, dipping, or otherwise applying a release layer between the support structure and the part so that these separate items do not become fused together during sintering. 1. A method comprising:fabricating a support structure for an object from a first material;fabricating the object from a second material, the object including a surface positionable adjacent to and supportable by the support structure, wherein the second material includes powdered material for forming a final part and a binder system including one or more binders, wherein the one or more binders resist deformation of a net shape of the object during processing of the object into the final part;applying an interface layer to a least one of the support structure and object at a location corresponding to the surface of the object positionable adjacent to and supportable by the support structure, wherein the interface layer resists bonding of the support structure to the object during sintering; andassembling the support structure and the object together with the surface positioned adjacent to and supported by the support structure, thereby providing an assembled workpiece.2. ...

A method of generating a mold and using it for printing a three-dimensional object

Принадлежит: Addleap AB, Desktop Metal Inc

This invention relates to three-dimensional printing. This invention in particular relates to a method of generating mold and printing a three-dimensional object. The mold thickness is controlled and holes are generated in the mold surface for releasing moisture easily. The mold surface having holes is designed initially digitally and then combined with the three-dimensional model before printing the three-dimensional object. In case the thickness of the mold surface is more then it reduces the overall quality of the three-dimensional object. When the model is enclosed inside the mold, there will be some residue moisture in the model even if the drying apparatus can improve this by drying layer by layer. This affects the final quality of the part. A solution of these problems is provided in the present invention. The thickness of the mold layer is between 0.5 to 1 mm and holes having 0.1 to 0.4 mm diameter. The holes are evenly distributed on the mold. The mold having the holes is prepared from which moisture can easily escape. A method of digitally generated a mold having thin layer and holes is used for fabricating three dimensional objects with high precision and quality.

Formulations with active functional additives for 3d printing of preceramic polymers, and methods of 3d-printing the formulations

Номер: US20220177373A1
Автор: John H. Martin, Kenneth CANTE, Tobias A. Schaedler, Zak C. ECKEL
Принадлежит: HRL LABORATORIES LLC

This invention provides resin formulations which may be used for 3D printing and pyrolyzing to produce a ceramic matrix composite. The resin formulations contain a solid-phase filler, to provide high thermal stability and mechanical strength (e.g., fracture toughness) in the final ceramic material. The invention provides direct, free-form 3D printing of a preceramic polymer loaded with a solid-phase filler, followed by converting the preceramic polymer to a 3D-printed ceramic matrix composite with potentially complex 3D shapes or in the form of large parts. Other variations provide active solid-phase functional additives as solid-phase fillers, to perform or enhance at least one chemical, physical, mechanical, or electrical function within the ceramic structure as it is being formed as well as in the final structure. Solid-phase functional additives actively improve the final ceramic structure through one or more changes actively induced by the additives during pyrolysis or other thermal treatment.

Monomer formulations and methods for 3d printing of preceramic polymers

Номер: US20180148380A1
Автор: Andrew P. Nowak, April R. Rodriguez, Ashley M. Nelson, Zak C. ECKEL
Принадлежит: HRL LABORATORIES LLC

This invention provides resin formulations which may be used for 3D printing and pyrolyzing to produce a ceramic matrix composite. The resin formulations contain a solid-phase filler, to provide high thermal stability and mechanical strength (e.g., fracture toughness) in the final ceramic material. The invention provides direct, free-form 3D printing of a preceramic polymer loaded with a solid-phase filler, followed by converting the preceramic polymer to a 3D-printed ceramic matrix composite with potentially complex 3D shapes or in the form of large parts. Other variations provide active solid-phase functional additives as solid-phase fillers, to perform or enhance at least one chemical, physical, mechanical, or electrical function within the ceramic structure as it is being formed as well as in the final structure. Solid-phase functional additives actively improve the final ceramic structure through one or more changes actively induced by the additives during pyrolysis or other thermal treatment.

Yaw brake pad and method of producing the same

Номер: US20200141462A1
Автор: Pengfei Zhang
Принадлежит: Individual

Provided are a yaw brake pad and a method of producing the same, which relate to the technical field of friction material. The yaw brake pad is prepared from, by weight, the following main ingredients: 70-75 parts of polyether ether ketone, 10-20 parts of carbon fiber, 3-5 parts of glass fiber and 3-5 of graphite. It alleviates the technical problem that the metal-based friction materials generally for producing current international and domestic yaw brake pads are likely to rust, harmful to dual discs, and produce screechy. It has not only significantly improved mechanical properties and high temperature tolerance, much lower hardness, less wear to dual discs, and lower noise, but also improved friction stability and adaptability to working conditions, and thus can effectively satisfy the demand of the wind driven generator for yaw braking at a low speed.
