White Styrene
High Impact Polystyrene Sheet (HIPS) is a white thermoplastic with excellent heat forming properties. Styrenes low melting point means it needs to be laser cut with special attention. Simple shapes work best as intricate detail tends to melt and be lost. The sheets have tendency to warp as it heats up when being cut so be sure to allow lots of space in between the pieces. Styrene does not engrave very well. Line engraving is favored over area engraving and intricate details are not recommended. Typically a etched line will disrupt the surface tension of the material and cause it to snap rather than to fold.
