Resposta direta à questão de saber se a impressão 3D em areia é mais económica do que a fundição tradicional – a regra do ponto de equilíbrio em termos de complexidade e quantidade, os cálculos reais dos custos dos moldes e o panorama do custo total de propriedade (TCO) para as fundições.

Uma análise sincera dos limites da impressão 3D em areia — dimensão, rendimento, resistência do molde, acabamento superficial, estrutura de custos, competências —, com soluções alternativas e uma lista de situações em que não se deve recorrer a esta técnica.
