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 of 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

Additional Projects
Northeast
Cornell University, Warren Hall
The original building has replacement aluminum windows and monumental steel-framed windows, and the extension has its original steel-framed windows. SGH was the building enclosure consultant and structural engineer of record for the comprehensive building renovation.
Northeast
University of Massachusetts, John W. Olver Design Building
A steel- or concrete-framed structure would be the conventional choice for this building’s size and use, but the new Design Building features a mass timber superstructure to maximize renewable materials. SGH was the engineer of record for this project.
