T/CI 098-2022 Technical Specifications for Fused Deposition Modeling (FDM) 3D Printers

Scope

Scope: This document specifies the terms and definitions, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of fused deposition modeling (FDM) 3D printers. This document applies to desktop 3D model printing devices that use the extrusion forming process in additive manufacturing of FDM 3D printers. Other types of extrusion-based desktop 3D printers using other materials may also refer to this document for implementation. (Hereinafter referred to as "printers") Main technical content: Additive manufacturing is a process that uses three-dimensional model data to fabricate solid parts by gradually adding materials. 3.2 Nozzle One of the core components of 3D printing devices, the nozzle melts and extrudes printing materials onto the print platform or the previous layer of printed materials according to the controlled trajectory. It is typically made of materials with good thermal conductivity such as brass. 3.3 Fused deposition modeling An additive manufacturing method that melts and extrudes thermoplastic materials from the nozzle to achieve stacked forming. 3.4 Fused deposition modeling desktop 3D printers Printing devices that generate print paths by slicing three-dimensional models with software and extrude molten materials using the print nozzle or other printing technologies to form three-dimensional objects layer by layer according to the specified path. They are characterized by small size, intended for personal and home use, and can be placed on a desktop for operation. 3.5 Printing layer thickness The thickness of a layer printed by the nozzle. 3.6 Maximum molding size The range of molding in the X, Y, and Z axes when the printer is in operation. 4 Technical Requirements 4.1 Appearance 4.1.1 The appearance of the product should be clean, with no dents, scratches, cracks, deformations, or contaminations on the surface. The surface coating should be uniform, without obvious
