摘要:
A nozzle (300) for dispense of a material that is a composite of fillers such as short fibers (e.g. carbon fibers) and a polymer matrix. The nozzle through which the composite material is dispensed has an expansion region (340) through which the composite material flows. The expansion region dispenses a composite material wherein the fibers are substantially not aligned (e.g. in a random orientation with respect to each other in the polymer matrix).

3D물체를 성형하는 3D 프린터가 개시된다. 본 발명에 따른 3D 프린터에 있어서, 프레임; 프레임에 설치되고 광경화성 액상수지를 일정한 압력으로 밀폐수용하는 수지조; 수지조 내에서 광경화성 액상수지에 침지되어 3D 성형물을 지지하는 조형판; 액상수지에 침지하여 조형판과의 사이로 액상수지가 침투하도록 하는 투명바닥판과 투명바닥판을 지지하는 하우징으로 이루어지고 액상수지로부터 압력을 받는 광학하우징; 광학하우징과 같이 승강하며 광학하우징의 투명바닥판과 조형판 사이의 액상수지를 향하여 노광하여 성형층을 형성하는 노광유니트; 및 광학하우징 및 조형판 중 어느 하나를 상대적으로 이격하도록 구동하는 구동부를 포함하는 것을 특징으로 한다. 본 발명에 따른 3D 프린터는 조형판이 상부를 향하도록 하고 조형판과 대향하는 광학하우징의 투명바닥판과 조형판 사이의 성형면에 광학하우징에 인가되는 액상의 수지의 압력을 이용하여 액상의 수지가 원활히 침투하여 기포없는 3D물체의 성형이 가능하다. 또한, 조형판의 상부를 향하여 3D성형물이 적층 성형하므로 조형판에서 3D성형물이 분리되는 문제를 방지한다.
摘要:
In some examples, an apparatus includes a plurality of conduits to transport a material of a three-dimensional (3D) printing system between locations in the 3D printing system. A sensor assembly detects a clogged condition of a first conduit of the plurality of conduits. A valve assembly connected to the plurality of conduits selectively controls flow of the material through the plurality of conduits, the valve assembly controllable to actuate from a first setting to a second setting responsive to the detected clogged condition.
摘要:
Devices and methods are described that provide printing of three-dimensional objects using reactive materials such as materials that result in a polyurethane formulation. Three- dimensional printing in accordance with the present disclosure can be performed using an inkjet printer or other systems that deposit or dispense material. A formulation made up of two or more reactive materials and, optionally, one or more UV-curable materials is also provided. The materials can be jetted based on a desired configuration to achieve a maximum reaction between materials, and can be based on desired jetting or molar ratios. By heating or applying energy on the jetted materials, their reaction and related solidifying can be accelerated. Corrective printing is also provided for, and can be used at desired intervals to eliminate printing errors relative to the object as modeled. Systems and methods used in conjunction with all of the same are provided.
