1 1 Original equipment manufacturer.

2 2 Computer‐aided design.

3 3 An alternative approach is specialized platforms such as Shapeways or Materialise (Wolff and Kern 2019) that offer “printing on demand” services to consumers (Rayna et al. 2015).

4 4 A subject matter expert in a study by Mellor, Hao, and Zhang relativizes this, suggesting that “in terms of material usage … particularly with the metals it's very good but you have to go through a high energy process of turning it into powder in the first place, do you really gain a benefit there? It's marginal to be fair. The actual machines are they really efficient at building stuff now? No … In terms of efficiency of use of energy they are not very good at all (Mellor et al. 2014).”

5 5 For an overview about the main services offered by 3D printing platforms cf. (Rayna et al. 2015).

6 6 She suggests that this could be overcome by regulating software instead of physical objects. As AM machines manufacture objects according to specifications provided in a design plan, product safety could be addressed by controlling the sharing of created plans and preventing unsafe ones from being distributed or sold (Neely 2016).

7 7 The seven categories are photopolymerization (including the technologies VAT, SLA, DLP, CDLP), powder bed fusion (DMLS, SLS, SLM, MJF, EBM), material extrusion (FDM), material jetting (MJ, NPJ, DOD), binder jetting (BJ), sheet lamination (LOM, SL), and directed energy deposition (DED, LENS, EBAM) (Wohlers 2012; Dassault Systèmes 2020).

8 8 Physical and mechanical properties differ with the part orientation.

9 9 Gartner explains all phases as follows. Innovation Trigger: A potential technology breakthrough kicks things off. Early proof‐of‐concept stories and media interest trigger significant publicity. Often no usable products exist and commercial viability is unproven. Peak of Inflated Expectations: Early publicity produces a number of success stories – often accompanied by scores of failures. Some companies take action; many do not. Trough of Disillusionment: Interest wanes as experiments and implementations fail to deliver. Producers of the technology shake out or fail. Investments continue only if the surviving providers improve their products to the satisfaction of early adopters. Slope of Enlightenment: More instances of how the technology can benefit the enterprise start to crystallize and become more widely understood. Second‐ and third‐generation products appear from technology providers. More enterprises fund pilots; conservative companies remain cautious. Plateau of Productivity: Mainstream adoption starts to take off. Criteria for assessing provider viability are more clearly defined. The technology's broad market applicability and relevance are clearly paying off (Gartner 2020).
