As the material is generated layer by layer the tray is gradually lifted and the photo inhibitors will not allow adhesion near the window. [13] Rapid, large-volume, thermally controlled 3D printing, using a mobile liquid interface. Another way to address the adhesion problem is to create a dead layer which prohibits the curing process.
Integrated into a Microgravity Science Glovebox (MSG), 3D Printing in Zero-G is a proof of concept experiment. It includes printing multiple copies of planned items to test for several variables, including dimensions, layer adhesion, tensile strength, flexibility, and compressional strength.
Delamination is a mode of failure where a material fractures into layers. A variety of materials, including laminate composites [1] and concrete, can fail by delamination. Processing can create layers in materials, such as steel formed by rolling [2] [3] and plastics and metals from 3D printing [4] [5] which can fail from
The intermediate layer is applied by spin-on, spray-on, screen-printing, embossing, dispensing or block printing on one or two substrate surfaces. The adhesive layer thickness depends on the viscosity, rotational speed and the applied tool pressure. The procedural steps of adhesive bonding are divided into the following: [1]
An example of how 3D printing can be included in the design process is automotive design. [19] There, it is necessary to quickly test and verify a prototype to get the design approved for production. The reduced post-processing steps induced by the multi-material 3D printing technology result in a shorter fabrication time.
Stereolithography (SLA or SL; also known as vat photopolymerisation, [1] optical fabrication, photo-solidification, or resin printing) is a form of 3D printing technology used for creating models, prototypes, patterns, and production parts in a layer by layer fashion using photochemical processes by which light causes chemical monomers and ...
Computer-aided design (CAD) model used for 3D printing. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting. 3D scanning is a process of collecting digital data on the shape and appearance of a real object, creating a digital model based on it.
In 3D printing, the bulk of each printed layer, regardless of complexity, is deposited by the same, rapid spreading process. [ 9 ] As with other powder-bed technologies, support structures are generally not required because loose powder supports overhanging features and stacked or suspended objects.
