3D Printing Technology and its Development Trend

Abstract

Abstract. 3D printing is an advanced manufacturing technology which is developing rapidly in near thirty years. Its advantages lie in simplifying producing process, reducing material waste, lowering production costs and meeting the spacial needs of different customers. At present, 3D printing is widely applied in various fields, such as mold manufacturing industry, aerospace, medial treatment etc. In this paper, the working principle and classification of 3D printing technology are elaborated in detail, the exiting problems are analyzed and the application trends of 3D technology are prospected in further.

Miniaturized application of 3D‐printed large‐flow microreactor in extraction and separation of platinum, palladium and rhodium

“…This process forms a three-dimensional product via layer-by-layer solidification of the molten wire material. 16,17 However, the precision of printed parts is low despite the low cost of this method. 18 By comparison, SLA uses photosensitive resin as the raw material, focuses on the surface of photocurable material using a laser with a specific wavelength and intensity, and solidifies it sequentially from point to line and line to surface to complete a layer of drawing operations; the lifting table moves the height of one layer in the vertical direction and then solidifies the other layer; layers are superimposed in this way to form a three-dimensional entity, [19][20][21] which is solidified and formed layer by layer using computer-controlled UV laser stone tools.…”

“…The fused deposition rapid prototyping process is a forming method that heats and melts wire material without relying on lasers as forming energy.
