A new method of pattern making brings various advantages, not the least of which is expanded design freedom. But 3D printing of patterns is not without trade-offs.
In casting, a mold produces the form of the cast part, while a pattern is used to make the form of this mold. Pattern making is therefore the heart of casting.
Danko Arlington is a company that recently turned to 3D printing—specifically, fused deposition modeling—as a potentially more efficient way to make castings. In a report on the company’s website, company president John Danko discusses the pros and cons of making patterns through additive manufacturing. According to Mr. Danko, those pros and cos include:

Yet another option, instead of 3D printing a pattern, is to 3D print the mold itself directly in sand.
