YouTuber Patrick Gibney presents a 3D-printed “Invisibility Shield” in his latest video. This is a 3D-printed plate made from transparent PETG filament, which creates a deceptively real camouflage effect. Thanks to the lens structure, objects behind it become almost invisible, similar to the lenticular lenses of modern flat-screen televisions.
According to Gibney, the secrets to a successful invisibility shield lie in the correct print settings: A layer height of 0.25 mm and an extrusion temperature of 210°C for the PETG material used ensured clear printing results. Support structures stabilized the object during the printing process, which lasted several hours.
The finished, transparent sign can be easily removed from the printing plate. Simply cut off the diagonally printed base part and align the now self-supporting lens grid. If you now place an object behind the “camouflage shield”, it will be almost completely obscured by the lenticular refraction of the print lines.
The YouTuber makes the STL files for 3D printing the “Invisibility Shield” available to interested parties free of charge on Thingiverse.
