#Titanium <br> <br>[a]https%3A%2F%2Fwww.gjprototyping.com%2Ftitanium-3d-printing-service%2F[/a] <br> <br>Titanium 3d printing service for Titanium alloy parts has very high strength, precise dimensions, and their mechanical properties are better than the forging process. Because of its good bio compatibility and excellent mechanical properties, titanium alloys are mainly used in biomedical materials, aerospace, and precision instruments. <br> <br>Titanium 3D Printing Material Properties <br>3D printing technology began to appear in the 1990s. Its development is based on high-energy thermal cladding technology and rapid prototyping technology. Compared with traditional manufacturing technology, it does not need to go through various cutting tools and a variety of complicated processes. The processing time is reduced, and the processing and manufacturing accuracy of components with complex structures are higher. At present, titanium alloy products have been applied in many fields. The structure of these products is relatively complicated, the variety is large, the batch is small, and the performance requirements are high. Traditional manufacturing technology cannot meet the requirements of these products, while 3D printing technology can meet the requirements of titanium alloy products. Manufacturing technology and performance requirements have been widely used. <br> <br>Print the advantage of Titanium 3D Printing <br>3D printing technology began to appear in the 1990s.

Manufacturing technology and performance requirements have been widely used. <br> <br>Titanium 3D Printing Materials Info <br>Titanium alloy has the following excellent characteristics <br>1 <br>High specific strength. The density of titanium alloy is only 60% of steel. The strength of pure titanium is close to that of ordinary steel. Some high-strength titanium alloys exceed the strength of many alloy structural steels. Therefore, the specific strength (strength/density) of titanium alloy is much greater than other metal structural materials, and parts with high unit strength, good rigidity and light weight can be manufactured. <br> <br>2 <br>High thermal intensity. The service temperature of titanium alloy is several hundred degrees higher than that of aluminum alloy, and it can work for a long time at a temperature of 450℃~500℃. The working temperature of aluminum alloy is below 200°C. <br> <br>3 <br>Good corrosion resistance. Titanium alloy works in moist atmosphere and sea water medium, its corrosion resistance is far better than stainless steel, and its resistance to pitting corrosion, acid corrosion and stress corrosion is particularly strong. <br> <br>4 <br>Good low temperature performance. Titanium alloys can still maintain their mechanical properties at low temperatures. For example, TA7 can maintain a certain degree of plasticity at -253°C. Therefore, titanium alloy is also an important low-temperature structural material. <br> <br>There are include Titanium 3D Printing materials <br>Ti6Al4V <br> <br>If you are looking for a reliable product prototype maker, don&#039;t hesitate to contact us! <br> <br>For more information about prototype service, please feel free to contact us!

#Prototyping <br> <br>[a]https%3A%2F%2Fwww.gjprototyping.com%2Fsilicone-prototyping-service%2F[/a] <br> <br>Soft Rubber rapid prototype, Hardness is generally between shore A 30~90 degrees, because soft rubber plastic prototype has flexibility, it is widely used in the rapid prototype industry. The processing method of soft plastic rapid prototype is relatively single, and it can only be processed by vacuum Casting - that is use 3D printing or CNC processing to do a prototype, and then use vacuum casting /silicone mold to copy the prototype, generally a prototype can be copied 15~20 time. <br> <br>Silicone Prototyping Material Properties <br> <br>In the general plastic industry, PP, PE and other light gravity, material surface hardness is relatively low plastic known as soft glue. And PS, ABS, AS, hard PVC and other plastics can be called hard glue. <br> <br>Heat resistance properties <br>Silicone products are silicon - oxygen (Si-O) key chain structure, C-C bond energy of 82.6 kilocalories/gram molecule, Si-O bond energy in silicone is 121 kilocalories/gram molecule, so the thermal stability of silicone products is high, high temperature (or radiation) molecular chemical bonds do not break, do not decompose. Silicone not only can withstand high temperature, but also low temperature, can be used in a wide temperature range. Both chemical and physical mechanical properties change very little with temperature. <br> <br>Silicone cast prototypes Material Info <br>Brief introduction <br>Soft prototype silicone rubber parts is mainly processed by the way of silicone compound mold, its advantages are fast time, less cost, good operation, no deformation, no shrinkage, easy to dismantle the mold, the mold surface is smooth, the simulation effect is good, the probability of processing failure is small. 10-20 pieces of the same product can be copied by using a silica gel mold. Generally, a set of silica gel mold can only be done about 10-20 times and can not be used. Reuse can produce deformation and large size error. Soft rubber hand model because of these excellent properties, so its application is very wide, Soft rubber hand model production steps can be divided into three steps, before making silica gel mold, first of all to make a prototype, the prototype can use the more common ABS material, can be made by CNC processing or 3D printing; After the original is ready, began to make silica gel mold, after curing, the silica gel mold is cut, take out the prototype, at this time the silica gel mold is ready; The liquid material is injected into the silica gel mold and dried. The service life of the silica gel mold is about 10-20 times. In the raid prototype industry, as long as the soft adhesive material is PU 8400. <br> <br>For more information about types of rapid prototyping and product design prototype, please feel free to contact us!
