Abstract
The invention discloses a 3D printing material, a printing method and a printing device based on a fused deposition manufacturing process. The material of the invention is composed of a base material and a curing agent. The method of the invention uses a resole phenolic resin under certain acidic conditions The principle of rapid cross-linking and curing, mixing and curing at the position where molding is required and depositing molding, products with different properties can be produced through different proportions. The device of the present invention is composed of a first material cylinder device, a second material cylinder device and a nozzle device, the lower ends of the first material cylinder device and the second material cylinder device are respectively fixed on the nozzle device, the first material cylinder device and the second material cylinder device The structures of the two material cylinder devices are exactly the same. The raw materials of the invention are cheap, easy to obtain, environmentally friendly and pollution-free, and will not cause harm to the human body. The manufacturing process of the material is simple and easy to operate. Suitable for a wide range of applications.
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 ...
