Many rapid prototyping methods are used for rapid prototyping of hand board. Let's take a look at it together:
Melt deposition process melt deposition (FDM) process is to melt the filamentous thermoplastic material at a specific temperature to keep the material in a liquid state all the time and extrude it at a uniform speed through the extrusion head. Under the control of molding data, it is selectively deposited on the working platform, cooled and solidified immediately after deposition.
Stereolithography process stereolithography (SLA) process makes use of the material characteristics of photosensitive resin, that is, the phase transition from liquid to solid can be realized under the irradiation of ultraviolet beam with certain wavelength and intensity. The trajectory of UV beam is controlled by molding data, and selective scanning is carried out on the surface of photosensitive resin to realize point by point curing molding.
Three dimensional printing process the principle of three dimensional printing (3DP) process is the bonding molding of powder materials under the action of adhesive. Firstly, a layer of powder material is paved on the working platform, and then the nozzle is used to distribute the adhesive in the powder area to be formed, so as to realize the adhesive forming of the powder.
Selective laser sintering process the principle of selective laser sintering (SLS) process is the melting and bonding of powder materials under laser sintering. A layer of powdery material close to the melting point is paved on the working platform, and then the laser is used to selectively scan the layer of powder. The powder temperature in the scanned area increases, and then sintered.
