At St. Petersburg State University of Industrial Technologies and Design (SPbSUPTD), a technology has been developed for creating durable products from a mixture of polymer and wood flour using 3D printing. This was reported by the press service of the Ministry of Education and Science of the Russian Federation.
Specialists at SPbSUPTD have managed to combine FDM and LDM printing in one method. This avoids interrupting the production process due to the printer nozzle becoming clogged with large particles of the mixture.
Using FDM technology, we print the shape of the product using ordinary water-soluble plastic. Then, we fill this shape with a mixture of modified epoxy resin, which acts as a binder, and wood flour using LDM printing.
The mixture is poured into the printed form, rather than layered. This makes it possible to obtain smooth products.
After hardening, the product is placed in a water bath, where the plastic contour of the form dissolves. The result is a solid composite made from a mixture of wood flour and polymer.
The development was tested at a factory in St. Petersburg. Specialists managed to replace imported blades for moving finished packaging with more durable ones.
Earlier, www1.ru reported that Rosatom scientists began printing individual titanium implants on a 3D printer.
