As the acceptance and use of Additive manufacturing methods increases, so does the demand to increase the geometric accuracy of products. The additive manufacturing process produces products of fair geometric quality but is nowhere near as geometrically accurate as its counterpart, subtractive manufacturing. Here I review the processes of additive manufacturing that cause a decrease in geometric accuracy. As processes that cause geometric inaccuracy are highlighted; the additive manufacturing process comes closer to producing products capable of maintaining a high level of geometric accuracy.

1.Intro
Additive manufacturing (AM) methods in product development and manufacturing are projected to grow over 300% within the next 10 years (Columbus). The increase in AM methods is a result of AM’s ability to create products with complex internal and/or external geometry in a timely and cost-effective manner (Columbus). Members of the medical field rely on AM to create models for pre-surgery planning as well as structures inserted into patients (Petzold).
Background
AM can create complex geometries; however the manufacturing method struggles to maintain geometric accuracy in products (Ameta). Geometrically inaccurate products manufactured for use in the medical field may subject patients to unnecessary complications that could have been avoided if geometric tolerances were kept. Here I review, research that studied the parameters of the AM process and the role each parameter plays…
