I used it to measure the tensile strength of 3D printed coupons for PETG, ASA and Nylon. The stand is strong enough. The whole kit is good value for money - for a small lab or DIY workshop - but be sure to read and follow the instructions in the review posted by Andrew. I followed these instructions and am happy to report that everything works including the stand, force gauge, RS232 connection to the gauge and the Windows software for logging and plotting.
