Design and manufacturability data on additively manufactured solutions for COVID-19

Abstract

Designers around the world have leveraged the rapid prototyping and manufacturing capabilities of additive manufacturing (AM), commonly known as 3D printing, to develop numerous engineering design solutions for the COVID-19 pandemic. This dataset consists of the design and manufacturability data for twenty-six such engineering design solutions spanning three categories: (1) face masks (N = 12), (2) face shields (N = 6), and (3) hands-free door openers (N = 8). The designs were collected from open-source websites such as Thingiverse, GrabCAD, and the NIH 3D Print Exchange. The manufacturability of these designs was simulated using Ultimaker Cura software and three measures were obtained: (1) build time, (2) build cost, and (3) build material. Furthermore, these simulations were performed for multiple materials and infill densities for comparison. Additionally, the manufacturing cost using injection molding was simulated using the Cost Estimation Tool in Solidworks. This dataset comprises (1) the STL files for the designs, (2) the simulated manufacturability data (for additive manufacturing and injection molding), and (3) images that depict the build orientation used in these manufacturability simulations. This dataset can facilitate the development of future innovations that leverage the capabilities of AM processes. Furthermore, this dataset can be used by designers and manufacturers to compare solutions and choose appropriate ones for manufacturing.

Maximizing design potential: investigating the effects of utilizing opportunistic and restrictive design for additive manufacturing in rapid response solutions

“…We identified 26 unique designs in three categories: 12 face masks, 6 face shields and 8 hands-free door openers. A summary of the various designs, the sources from where they were retrieved from and the corresponding STL files are publicly available in an online repository at Prabhu (2021cPrabhu ( , 2021d. It should be noted that we only used the latest versions of these designs in our data set.…”

“…face masks could be much larger in size than face shields), we normalized the manufacturing efficiency data within each solution type to enable comparisons across the three sets of designs. The manufacturing efficiency data for the designs is made publicly available in an online repository [see Prabhu (2021cPrabhu ( , 2021d]. The publicly available data set also comprises data for other filament materials (e.g.…”
