Design Notes

This material will stick to any ferrous/magnetic surface including those which are curved. The attraction force is moderate and works best in full contact with the surface to which it is sticking. Additionally, particles from cutting lines will stick to your designs. These can be brushed off or blown off with compressed air.

Because this material is so thin and flexible, intricate details can cause it to deform. Caution is advised for very detailed & intricate cuts.

This material arrives without protective paper or film so some surface marking is possible. It is also cut without paper on the top surface to produces the best engraving results.

Since the top layer is very thin, the underlying substrate is sometimes visible along the cut line as well - this is most noticeable in corners or angles of your design.

Engraving Laserable Magnet

This material engraves well with the underlying substrate revealed in the engraved areas. This is great for details such as text and graphics. Keep in mind larger areas may result in powder build up.

There are 3 types of engraving possible with laser cutting. Area engraving, line engraving and a combination of both.

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 0.1-0.5mm.

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.

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

This material works best as a 2D magnet. It's not expected that structures or 3D constructions will be made from this material.

Typical Uses

This material is good for making fridge magnets, promotional magnets, repositionable nameplates, vehicle graphics etc

Environmental Information

PET is recyclable in some areas.

Adhesives, joints and fastenings

Join with elastic cements that remain flexible, such as caulks, polysulfides and rubber based adhesives. Pressure sensitive, doublefaced tape, depending on the end use, may also be suitable for joining this material to other materials.
