3D printing has come a long way in recent years. Speed, high ease of use and other advantages of 3D printing has become a trend, and in many areas have been applied. Today, 3D printers have been used in architectural design,medical auxiliaries, industrial models, complex structures, spare parts, animation and other fields have a certain degree of application. Especially in the aircraft, nuclear power and thermal power and other heavy machinery,high-end precision machinery industry, 3D printing technology "print" products are seamlessly connected to the structure, the stability between the structure and connection strength is much higher than the traditional method.

Advantage:
1: No additional cost for manufacturing complex items
2: product diversification does not increase the cost;
3: zero time delivery;
4: unlimited design space;
5: zero skill manufacturing;

Indeed 3D printing has many advantages.So,3D can replace the injection mold?

1,Can’t achieve tight tolerances
3D printing is still in it’s infancy.  You can only achieve a certain amount of detail in the final product and, compared to a metal mold, is nowhere near the tolerances offered.  These molds are subject to all the persnickety problems that are inherent to 3D printing too…warping, curling and cracking. If the mold fails to print correctly,you’ll have to throw it out and start again.

2, The material restrictions
Careful observation of some of the items and equipment around you, you will find the first stumbling block 3D printing,that is the required material constraints. Although high-end industrial printing can achieve plastic,some metal or ceramic printing, but can not achieve the printing of materials are more expensive and scarce.

3, The machine limit
As we all know, 3D printing to become mainstream technology (as a consumption of large technology), its requirements on the machine is not low, the complexity can be imagined. The current 3D printing technology has achieved a level of geometry and function in reconstructing objects, and almost any static shape can be printed,but those moving objects and their sharpness are difficult to achieve.

4,Intellectual property rights concerns
Over the past few decades, there has been a growing interest in intellectual property in the music, film and television industries. 3D printing technology will undoubtedly be related to this problem, because in reality a lot of things will be more widely spread.

5, The cost
3D printing technology needs to bear the cost is high, This is especially true of the general public.

Verdict:  Printing 3D molds for injection molding produces no benefit when compared to our injection molding process.
