"Addictive" Manufacturing

30-09-19 Mouldmaking on additive manufacturing

In the future one can forsee good news for additive manufacturing;

Lets have a short glance:


Of course everyone wants to get their final / end, ready to use, products  out of their 3D printing machines (being that plastics or metal);

But, in the mouldmaking, for the time, it must be balanced costs, surface quality, available materials under the requirement context, accuracy, time and processes (at least).

Nevertheless, the benefits of having custom parts with complex geometries that otherwise would be almost impossible to be done, could have a good return;

Additive manufacturing (AM), or 3D printing, in moldmaking and molding will continue to progress as more players in the industry see results from the early adopters and gain more confidence to add it to their business strategy. Early adopters have already done groundbreaking work, driving additive material vendors to develop more and different additive material to expand uses, as well as driving the additive machine makers to listen to feedback on what has worked, what has not and what is needed to progress further. On the molding shop floor, early adopters have deduced what is required to maintain and keep additive inserts working as they were designed to do.

Conformal cooling arises quickly in conversation with molders and moldmakers when additive manufacturing is mentioned. Companies that specialize in additive-created conformal cooled inserts work with OEMs and moldmakers and can run simulation to show the before- and aftereffects of using a conformal insert. Accuracy is paramount in these analyses and has a direct bearing on ensuring heat removal to properly address pressure drops and Reynolds numbers. It is possible to design an insert that would not be useful due to a large pressure drop that minimizes turbulent flow to remove the heat.


Hybrid designs are now being seen where the base of the cooling insert is manufactured with traditional subtractive methods, and then the complex conformal areas are added on top of the base piece. This approach can allow for more acceptable pressure drops, while still providing the benefits of very localized heat removal. It can also lower costs and lead times for producing the entire insert. 

In conclusion, AM in molding and moldmaking has found a home, but not all the rooms are occupied. There are many companies that have already been successful at implementing this strategy to help with productivity and costs, and there will be many more that jump on the bandwagon. It will take more time, with more case studies and some pitfall analyses to further prove out its value, but this technology is here to stay (...)
