Abstract

The invention discloses a 3D printing material based on a fused deposition manufacturing process, a printing method and a printing device. The 3D printing material is composed of a basic material and a curing agent. The printing method includes that a principle that A-stage phenolic resin can realize quick crosslinking and curing under a certain acidic condition, mixing curing and deposition modeling are performed at a position needing modeling, and products different in performance can be produced through different proportions. The printing device is composed of a first material barrel device, a second material barrel device and a nozzle device, the lower end of the first material barrel device and that of the second material barrel device are fixed on the nozzle device respectively, and the first material barrel device and the second material barrel device are completely identical in structure. Raw materials are low in cost, easy to obtain, environment friendly and free of pollution and damage to human body, the 3D printing material is simple to manufacture and easy in operation, the printing device is simple, convenient to operate and maintain, low in maintenance cost, simple in material extruding process, supportive of low-temperature modeling and suitable for wide application.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a 3D printing material, printing method and printing device based on a fused deposition manufacturing process. Background technique [0002] Additive Manufacturing (AM) is a manufacturing technology that is directly driven by a CAD model and quickly generates arbitrarily complex three-dimensional entities (3D). It fundamentally breaks through the traditional two processing methods of forced processing and removal forming in mechanical manufacturing. A new process method of growth-type manufacturing is adopted. According to its process, it is divided into: stereolithography rapid prototyping (SLA), laminated solid manufacturing (LOM), selective laser sintering (SLS), three-dimensional printing (3DP) and fused deposition modeling (FDM), etc. The basic principles of the process are the same. Yes, it is based on the idea of ​​discrete / stacking. According to the 3D CAD model, after format ...
