Chen said that testing of the new prototype has shown it saves around 35% in materials used to print objects. The pins rise up as the printer progressively builds the product. The new prototype instead uses a programmable, dynamically-controlled surface made of moveable metal pins to replace the printed supports. Traditional 3-D printing using the Fused Deposition Modeling (FDM) technique, prints layer-by-layer, directly onto a static metal surface. The work, led by Yong Chen, professor of industrial and systems engineering and PhD student Yang Xu, has been published in Additive Manufacturing. Epstein Department of Industrial and Systems Engineering have created a low-cost reusable support method to reduce the need for 3-D printers to print these wasteful supports, vastly improving cost-effectiveness and sustainability for 3-D printing. The materials the supports are made from often cannot be re-used, and so they’re discarded, contributing to the growing problem of 3-D printed waste material.įor the first time, researchers in USC Viterbi’s Daniel J. However, these supports must be manually removed after printing, which requires finishing by hand and can result in shape inaccuracies or surface roughness.
However, the process also creates a large amount of expensive and unsustainable waste and takes a long time, making it difficult for 3-D printing to be implemented on a wide scale.Įach time a 3-D printer produces custom objects, especially unusually-shaped products, it also needs to print supports–printed stands that balance the object as the printer creates layer by layer, helping maintain its shape integrity. Image/Yong Chenģ-D printing has the potential to revolutionize product design and manufacturing in a vast range of fields-from custom components for consumer products, to 3-D printed dental products and bone and medical implants that could save lives. These are not included on this page or the next.A new dynamically-controlled base for 3-D printing (center) will reduce the need for printed supports (left), cutting wastage and saving time.
Please note: Among the resulting 97 titles, 27 are facsimiles or reprints. To refine our search in order to limit the number of our incunabula printed during the earliest period of typography (i.e., from the invention of the art of typographic printing in Europe in the 1450s to the end of the 15th century), a date range needs to be included in our search strategy: 1400-1501. Select "Advanced Search", limit your search to "Catalog", and then select "Subject" for the term, "Incunabula". To retrieve this result, use the following Search Strategy: The number of incunabula (original and facsimilies) currently in our USC libraries collections amounts to approximately 555 titles. Updates to such numbers will be made when new incunabula will be added to our collections. This information is the result of a catalog search undertaken in July 2020.
