Reflect-o-Lay is the first reflective filament for 3D printing FDM. This polymer is formed by flexibly PLA and small reflective particles. The large property of this filament is his great ability to reflect light intensively.

This filament has been developed by the prestigious German engineer Kai Parthy based on the principle of retro-reflection of light. As explained by the manufacturer Reflect-o-Lay filament reflects light (Wavefront) back to the source regardless of the angle of incidence.

Reflect-o-Lay it is a semi-flexible filament filled with millions of reflective pigments, which produce reflective points on the external surface of the filament and also finished printing. Therefore, the printed pieces with this filament will light up when they are in turn illuminated by other light sources.

The natural finish of Reflect-o-Lay filament is gray, but being in an environment of darkness and being hit by light beams becomes bright white.

This material is easily washable without losing the properties and is easy to pierce to be sewn for example to a garment.

3D printing filament Reflect-o-Lay is being used experimentally in the automotive industry for passive signaling elements. Another potential application is in devices having safety for cyclists, runners, climbers ... in order to increase visibility and thus increase safety. You can perform light signals, reflective markers or marking points at a great distance.

One of the most prominent applications has been in the field of fashion and functional accessories. Were made reflective accessories for clothing (reflective vests, etc.) since due to the possibility of being a filament seamable allows these can adhere to clothes. Featured as sunglasses, pet collars, reflective plates for hats or bags and a repertoire multiple accessories are some of the most widespread creations in this field with the filament for 3D printing Reflect-o-Lay.

To print with the Reflect-o-Lay filament is not necessary to have a hot bed in the 3D printer, although if it is advisable to have it is in between 45 and 60. It is advisable to use 3DLac, Kapton Tape o BuildTak to minimize the warping effect and therefore obtain the best print results.

The recommended temperature of extrusion is at 210 °C. Due to the semi-flexibility of the filament it is necessary to have a nozzle diameter of 0.4 mm.

After the print must be removed filament printer and load PLA filament for about 30 seconds to clean out any residue that may remain within the extruder.

Masterspool format

The 250 g. format of the Reflect-o-Lay filament can sometimes cause problems during the printing process because it does not include a spool that helps the correct supply of material from the 3D printer.

To avoid this type of problem when printing this and other filaments that are sold in masterspool format you can use a variable spool holder. Thanks to the use of this device, all kinds of tangles and overlaps derived from the absence of a spool are largely avoided.
