Design Notes

A flexible thermoplastic with a matt finish on both sides. Polypropylene is incredibly flexible and can be used for living hinges. Intricate detail for cutting is not recommended.

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.

Engraving Styrene

Due to its low melting point polypropylene does not engrave very well. Line engraving is favored over area engraving and intricate details are not recommended. There are 3 types of engraving possible with laser cutting. Area engraving, line engraving and a combination of both.

Line engraving is like a really shallow cut. To achieve this effect the stroke color to red with RGB values of 255, 0, 0 and set the stroke style to a width of 0.01 mm. The laser beam follows along the red lines that you have in your design and marks the surface of the material. The result is crisp but it can be a time consuming technique if you have a lot of small details like text.

Area engraving is great it you need to mark a large area on the surface of the material. To specify area engraving set your shapes to have a fill color of black with RGB values of 0, 0, 0. The way this engraving is performed is like an old dot matrix printer except instead of dots of ink it uses pulses of the laser beam. This is a surface finish not deep enough to be used for pocketing or inlays. The depth of the engraving ranges between 0.1-0.2mm.

Using a combination of both engraving types typically gets the best result. Set your shapes to have a fill color of black with RGB values of 0, 0, 0, the stroke color to red with RGB values of 255, 0, 0, and set the stroke style to a width of 0.01 mm. The line engraving causes the laser beam to trace around the edges of the engraved areas making them more crisp and bringing the details to life.

Construction Techniques

To achieve a 3D form polypropylene is typically heat formed or layered. Typically a etched line will disrupt the surface tension of the material and cause it to snap rather than to fold.

Typical Uses

Polypropylene is commonly used for making lamp shades, stationary, cutting mats, packaging, living hinges, architectural models, stencils, book marks, point of purchase displays, packaging, etc.

Environmental Information

Polypropylene is commonly recycled, and has the number '5' as its resin identification code.

Adhesives, joints and fastenings

Polypropylene can be heat welded.
