Back to Reality – What can Tabletop Printers Do? Sturdy parts Relatively low material costs Time tested technology (even if only at an industrial level) Lots of variety in the types of printers and printing supplies Low cost printers not always reliable Affected by temperature, humidity, etc. Cannot build models with gaps or hollow areas very well Lots of variety in the types of printers and printing supplies
