Advantages Of 3d Printing And Manufacturing Molds
- Jun 07, 2018 -

1) the mold production cycle is shortened

3D printing molds shorten the entire product development cycle and become the source of driving innovation.In the past, companies have sometimes delayed or abandoned product design updates because of the need to invest heavily in new molds.By reducing the production preparation time of the molds and enabling the existing design tools to be updated quickly, 3D printing enables enterprises to afford more frequent replacement and improvement of molds.It allows the mold design cycle to keep pace with the product design cycle.

In addition, some companies have purchased their own 3D printing equipment to make molds, which further accelerates product development and improves flexibility/adaptability.Strategically, it has improved the supply chain's ability to resist extended periods of time and to develop the risk of stagnation, such as getting inappropriate molds from suppliers.

2) lower manufacturing costs

If the cost of 3D printing of metals is now higher than that of traditional metal manufacturing processes, it is easier to cut costs in plastics.3 d printing of metal mold in small, discrete series production of end products have economic advantages (because fixed costs are difficult to amortize these products), or for certain geometry () for 3 d printing optimization more economic advantage.In particular, 3D printing has a cost advantage when the materials used are very expensive and the traditional mould manufacturing results in high scrap rate of materials.In addition, the ability of 3D printing to produce accurate molds in a matter of hours can have a positive impact on manufacturing processes and profits.Especially when production is down and/or tooling inventory is very expensive.Finally, it is common to modify the mold after the production starts.The flexibility of 3D printing enables engineers to attempt numerous iterations simultaneously and to reduce the upfront cost of tooling design modifications.

3) the improvement of mold design adds more functionality to the end product.

Usually, 3 d printing of metal special metallurgy method can improve the metal microscopic structure and produce fully dense print parts, and those forging or casting material (depending on the direction of heat treatment and testing) compared to its mechanical and physical properties of the same or better.Additive manufacturing provides engineers with unlimited options to improve mold design.When the target component is composed of several sub-components, 3D printing has the ability to integrate the design and reduce the number of components.This simplifies the product assembly process and reduces tolerances.

In addition, it can integrate complex product functions, so that high functional end products manufacturing speed faster, less product moral defects.For example, the overall quality of injection parts is affected by the heat transfer between the injected material and the cooling fluid flowing through the fixture.If made with conventional technology, the channel leading the cooling material is usually straight, resulting in slow and uneven cooling in the molded parts.3D printing can realize cooling channels of any shape to ensure that the cooling is more optimized and uniform with the shape, resulting in higher quality parts and lower scrap rate.In addition, faster heat removal significantly reduces the injection cycle, since the cooling time generally accounts for up to 70% of the entire injection cycle.

4) the optimization tool is more in line with ergonomics and minimum performance improvement

3D printing lowers the threshold to validate new tools that address unmet manufacturing requirements, allowing more mobile and fixed fixtures to be put into production.Traditionally, because of the considerable cost and effort required to redesign and manufacture them, the design of the tools and the corresponding devices have always been used for as long as possible.With the application of 3D printing technology, enterprises can renovate any tool at any time, not only those tools that have been scrapped and do not meet the requirements.

Due to the small time and initial cost, 3D printing makes it more economical to optimize the tool for better marginal performance.So technicians can think more about ergonomics in their designs to improve comfort, reduce processing time, and make them easier to use and store.While this may only reduce the assembly time by a few seconds, it doesn't add up.In addition, optimizing tool design can also reduce the scrap rate of parts.

5) customized molds help to achieve customization of final products

Shorter production cycles, the ability to make more complex geometric shapes, and the ability to lower final manufacturing costs allow companies to build a large number of personalized tools to support the manufacture of custom components.3D printing molds are very useful for customized production, such as medical equipment and medical industry.It can provide surgeons with 3D printed personalised devices, such as surgical guides and tools, that can improve outcomes and reduce surgery time.
