KUNXIN’s own fabrication guidance says thin sheets up to 3 mm are commonly score-cut for straight processing, and its forming article says acrylic becomes soft and bendable at around 150 to 160°C. Standard PMMA data sheets also place tensile modulus around 3200 MPa and flexural modulus around 3300 MPa, which confirms that 3mm acrylic has controlled stiffness with limited natural flex.
