Laser printer internal parts are prone to deformation when they are working in high temperature environment for a long time. resulting in machine faults such as paper jam and angle folding. In order to predict the deformation of parts in thermal environment and further determine their initial allowable deformation. so as to guide the structural design and production process of parts. https://www.roneverhart.com/2024-Easton-Speed-Comp-10-USA-Baseball-Bat-EUS4SPC10/
