Three-dimensionally Printed Glass Testing
Scope/Solutions
In 2017, SGH collaborated with the MIT Media Lab on an exhibit for Milan Design Week. The exhibit, Glass II, showcased intricately curved columns created with three-dimensionally (3D) printed silicate glass. We helped the team by designing post-tensioning support for the columns and performing physical testing in our Applied Science & Research Center. Looking to advance their research with a new geometry, MIT retained SGH to perform additional testing on 3D-printed glass samples in 2024.
SGH tested nineteen samples to determine the compressive strength of the assembly. Highlights our work include:
- Conducting tests on a single glass unit with flat-plate boundaries and on a stacked assembly
- Testing with wooden and/or aluminum mounts to simulate use-case loading conditions
- Using a hydraulic testing machine with a 600 kip capacity
- Targeting a load rate of 1 kip/sec and manually controlling the rate of compression to compensate for deformations as the glass pressed into the mounts
- Monitoring the load and displacement throughout the testing using data acquisition software
