Factors Affecting Dimensional Precision Of Consumer 3d Printing, David D. Hernandez
Factors Affecting Dimensional Precision Of Consumer 3d Printing, David D. Hernandez
International Journal of Aviation, Aeronautics, and Aerospace
This paper investigates the factors affecting dimensional precision of consumer-grade 3D printing, attempting to isolate and mitigate sources of error. The focus is on creating engineering prototypes of, tooling for, or finalized instances of mechanical devices. A specific fused deposition modeling printer – the Ultimaker 2 – is analyzed in terms of meeting precise physical dimensions, consistent shapes, and predictable surface finish. Extensive trial and error resulted in removal of several sources of bias, with square test articles exhibiting a lower-than-anticipated mean percentage error of -0.387% (SD = 0.559), a value comparable to other modern manufacturing techniques. A full …

Three-dimensional (3D) printers have gained popularity for use for many different projects. The work presented herein aims to make this process simpler. This poster discusses a system that will allow individuals from all over campus to submit object files for printing, without having to schedule appointments and schedule 3D scanning appointments and retrieve scan results.

Three-dimensional (3D) printers have gained popularity for use for many different projects. The work presented herein aims to make this process simpler. This paper discusses a system that will allow individuals from across campus to submit object files for printing by a 3D printer, without having to schedule appointment and manually operate it.
Logistical requirements dictate some level of human involvement, despite a goal of creating a fully automated system. Involvement areas include converting /preparing submitted files, sending the job to the printer, print tray preparation, and completed object removal. From a user’s perspective, however a seamless experience is anticipated. …
