If you ponder your 3D printing abilities are limited by the high end of your 3D printing device, you can want to take a appear at the massive repertoire of 3D printing device filament wizard Kai Parthy. The German inventor specializes in one-of-a-kind 3D printing filaments with functional properties that add a whole new dimension to any project, and he is always working on additional. For his latest project, Kai has created not just one, but four filaments: the LAY-AWAY series of soluble assist filaments, that encertain that assist is always ideally removed without damaging the main print.
Among his earlier designs, you can find materials such as the LayWoo-D3 wood filament (and not long ago the LAYWOOD-FLEX version), the flexible BENDLAY flex filament, the wax-like MOLDLAY and actually the sponge-like LAYFOMM. In December 2015 he introduced the shoe sole mimicking SOLAY filament, that was followed by the REFLECT-o-LAY filament in February 2016, that fundamentally mimics the reflective properties of traffic signs, safety jackets and bike reflectors. Many of them can now be ordered through your local filament dealer.


And as Kai explains to 3ders.org, great results breeds competition. “The market for 3D material development is expanding. There is now at quite least one primary developer in each industrialized country, and most tiny traders for FDM filaments as well,” he says.
But there is yet much that hasn’t been done preceding, and Kai again brings what he calls a series of ‘un-ordinary filaments’ to the table. As he explains, we’ve all struggled to 3D print particularly complex objects at a few point in our producing careers. “3D prints with overhang need assist structures, such as the balcony of a house, to encertain it does not fall down mid-print,” he says. But assist structures are not without their limitations, as they can be complex to remove ideally. Nothing really ruins a complex print as surface injure created during assist removal.


To be certain, there are other possibilities. By means of soluble filaments are frequently a ideal way to store prints fully intact. If you take place to have dual print heads, you can have tried PVA filament for assist structures– a thermoplastic polyvinyl alcohol that dissolves in water. Most significantly, its physiologically harmless. Users needing to 3D print temperature-stable objects in a heated create area a fewtimes use HIPS assists instead, a filament that washes off with Limonene solvent. Unfortunately, that solvent is really expensive, polluting and has a smell that lingers for a long time after use.
As Kai explains, water is just the most solvent around. It can be disposed of easily, does not affect the health of the user, costs quite little and is always on the market. That’s why he’s created it his undertaking to refine soluble PVA assist filaments for various types of various applications. The results consist of four various filaments, that are all dimensionally stable and have quite great adhesion properties.


The initially three of them are water-soluble, just like PVA. But unlike PVA, they are specifically suited for various projects. LAY-CLOUD is specifically dedicated for use with flexible prints, 3D prints at around 240 degrees Celsius and has the most polyurethane adhesion of the four. It is in addition quite effortless to remove: just plunge the print in water and the LAY-CLOUD falls away in a cloudy residue. LAYaPVA, meanwhile, showcases high levels of print viscosity and 3D prints at around 230 degrees Celsius. A material that remains stable during long tool-changing periods, it is in addition quite thermally stable and easily dissolves in water.
HIGH-T-LAY filament, in contrast, is especially meant for use in hot create rooms (of around 100 degrees Celsius). The ideal replacement for HIPS and the stinky Limonene, it prints at around 240 degrees Celsius and adheres ideally to ABS, POM, PC, PLA and other common filaments. HIGH-T-LAY dissolves in water rapidly, leaving just a flaky residue that can be removed with a brush.


The fourth material, finally, is various of all the others for one significant reason: it dissolves in alcohol. “ETHY-LAY just dissolves in alcohol (spirits). This is better for printed objects that must not come into contact with water,” Kai explains. It is ideal for projects involving sensitive bio prints, and can be easily 3D printed on an unheated create platform. It in addition does not need a quite high temperature (just around 165 degrees Celsius), so its heat won’t affect your delicate print either. Similar to the three other soluble filaments, it’s a ideal version for those odd projects requiring quite specific 3D printing properties. How can Kai amaze us following?
