An Intelligent Exhaust Gas Processing System for Desktop 3D Printer

Abstract

With the rapid development of 3D printing technology, desktop 3D printers have gradually become popular. The mainstream 3D printing technologies are FDM (Fused Deposition Modeling), SLA (Stereolithography), and SLS (Selective Laser Sintering). However, these 3D printing technologies will cause environmental problems during printing, and UFP (ultra-fine particles) and some harmful gases and dust will be emitted during work, which will affect human health. There is currently no treatment method for the pollution problem caused by 3D printing. In this paper, an intelligent exhaust gas processing system that can perform adsorption and catalysis is developed for desktop 3D printers such as FDM, SLA, and SLS. Using 51 single-chip microcomputers as the operation and data processing center, on the basis of manual control of the processor switches, a digital universal particle concentration sensor was adopted, and a new type of intelligent exhaust gas treatment system was designed based on the change of the internal particle concentration in the printer. In order to achieve the intelligence of the exhaust gas treatment.
