What is the difference between 3D Printing Models and resin molds?
3D Printing Models is a special tool for the production of handicrafts, silicone is characterized by high temperature, corrosion resistance, tear resistance, simulation fine high, is to do all kinds of crafts mold
Resin mold refers to the softening or melting range after heating, softening in the external force under the action of the flow tendency, at room temperature is solid, semi-solid, and sometimes can be liquid organic polymer. Broadly speaking, any polymer compound that can be processed as a raw material for plastic products is called a resin. Resin mold features Mainly excellent mobility, good operability, room temperature by adding curing agent 2% -3%, 30 minutes can also be operated, 2-5 hours after the formation, with no deformation, high temperature, Acid and alkali, no expansion and so on.
3D Printing Models and resin mold difference:
1, silicone rubber mold SLA, FDM, LOM or SLS and other technology to produce the prototype (model), and then turned into silicone rubber mold, the mold into the two-component resin-like liquid, after curing to get the required Components. Bridge tooling usually refers to the direct injection molding of epoxy resin mold.
2, the use of epoxy molds compared with the traditional injection mold, the cost of only a fraction of the traditional method, the production cycle is also greatly reduced. Mold life is less than steel mold, but higher than the silicone mold, up to 1000 ~ 5000, to meet the needs of small and medium volume production. Hard tooling usually refers to the steel mold, that is, the use of indirect manufacturing of metal molds and the rapid processing of metal molds.
According to the mold material, production costs, RP prototype materials, production batch, mold precision requirements have been developed a variety of process methods. The current rapid tooling methods are roughly indirect molding method and direct molding method, based on RP rapid manufacturing molds are mostly indirect molding method. According to the different materials, indirect molds produced by the mold with soft mold, bridge and hard mold, under normal circumstances refers to the 3D Printing Models, resin molds and steel mold.
The 3D Printing Models are mainly used in toys, gifts, fine patterns of products, for the package mold, pouring mold products, glass technology, lighting, candles, characters copy production mold, large pieces of products, open film, relief, Buddha, craft gift making mold, soles model, perfusion mold, sand casting.
There are several key trends driving car manufacturers to use for 3D Printing Models applications, for example, 3D Printing Models can be more and more prototype parts, the use of 3D Printing Models production concept model for the adaptation and final inspection, design verification, and even Create functional components that can be used for vehicle and engine testing.
In fact, the leading car manufacturers have been using the material manufacturing and 3D Printing Models to manufacture a variety of molds, fixtures, etc. for the assembly and manufacturing process. 3D Printing Models gradually dominate the application of modeling review, design verification, complex structural parts, multi-material composite parts, lightweight structural parts, custom special tooling, after-sales personality replacement parts and so on. These leading car manufacturers have developed their own characteristics of the 3D Printing Models application model. At present, including SLS, FDM, 3DP, PolyJet, SLM, SLA technology in the automotive field applications from interior to tire, air pipe, lid, pneumatic model, cylinder, cylinder head, fuel system, shell design and functional verification The These uses mark the future of 3D Printing Models technology to enter or enter a higher value-added manufacturing process, but also marks the car manufacturers at any time may be the use of 3D Printing Models technology for the direct use of the final use of automotive parts.
