COMBRINCK, J.; VAN AS, B.; BOOYSEN, G.J.  and  DE BEER, D.J.. Cost-effectiveness of Direct Metal Laser Sintered Maraging Steel Inserts for Plastic Injection Moulding Process. S. Afr. J. Ind. Eng. [online]. 2019, vol.30, n.3, pp.52-62. ISSN 2224-7890.  http://dx.doi.org/10.7166/30-3-2263.

This paper describes an investigation into the possible heat transfer benefits of conformal cooling channels using maraging steel MS1 inserts, which could result in a reduction of cycle times and cost per product, and improve part quality by eliminating defects such as warpage and heat sinks. A manufacturing cost and lead-time comparison showed that a conventionally manufactured insert reached its break-even point after fewer injection moulding cycles than an additive manufactured insert, due to its lower manufacturing costs. During high-volume production, the additive manufactured insert becomes more profitable to use, due to its shorter cycle times.
