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 ...
High-area rapid printing (HARP) is a stereolithography (SLA) method that permits the continuous, high-throughput printing of large objects at rapid speeds (Figure 1). [1] This method was introduced in 2019 by the Mirkin Research Group at Northwestern University in order to address drawbacks associated with traditional SLA manufacturing processes.
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.
A 3D printing company, MX3D based in the Netherlands is planning to print a 3D bridge over a canal in the center of Amsterdam. The inventors created a robotic structure that can fully rotate to ...
Formlabs is a 3D printing technology developer and manufacturer. The Somerville, Massachusetts-based company was founded in September 2011 by three MIT Media Lab students. The company develops and manufactures 3D printers and related software and consumables.
3D printing speed refers to only the build stage, a subcomponent of the entire 3D printing process. However, the entire process spans from pre-processing to post-processing stages. [7] The time required for printing a completed part from a data file (.stl or .obj) is calculated as the sum of time for the following stages:
Kansas City Southern Railroad Bridge, Cross Bayou (present-day) Only two known examples of Waddell's "A" truss still exist. Due to the design's significance with respect to both the progress of American civil engineering and the legacy of J.A.L. Waddell, each has been designated a National Historic Place for more than three decades.
Landmark bullet train bridge in Fresno is finally complete. ... will likely be seven to 10 more years before trains begin rolling over the viaduct and the rest of the 119 miles of the rail route ...
