Frequently Asked Questions
Material Drying | AirSafe AS1
The AS1 is no filament dryer. It will dry material only over a very long time of several days. The AS1 is intended to use as storage and feeding device for predried or freshly opened filaments. Please note that all our materials will ship in aluminum bags with a lot of dessiccant. You can put this material in the AS1 WITHOUT predrying. If you receive any material in transparent plastic bags with only a small sachet of desiccant, we recommend to predry it before printing or putting it in the AS1.
The Short Answer: Only dry plastics will extrude properly in your 3d printer’s nozzle. Also only properly dried materials will provide the wanted material properties, for instance stiffness or flexibility.
The Long Answer: Some material will bind water between their molecules – similar like your clothes in the washing machine. When the plastic is heated inside the nozzle, the water inside the plastic will vaporize and expand. This causes uneven extrusion and unhappy printing experiences. This will happen with materials like TPU or ABS. It will get even worse when the water is starting to damage the molecular structure of the plastic – called hydrolisis. This alters the pyhsical properties of the plastic, making it behave more like a fluid inside the nozzle. In worst cases this will make printing an impossible endevour. Sometimes it just makes the properties of your finished parts worse, like making them bear less load than intended.
Soluble Support Material | VXL Filaments
Yes, you can. You can use it for casting but also for making composite parts but wrapping carbon or glass fibers around the mold and fixing it with a duromer.
VXL is different from any other support material you may have tried before. Its chemical composition differs particularly from that of water-soluble materials such as PVA, BVA, and PVOH. You can use VXL as support material for almost every model material out there.* It will adhere well to your model materials and also effectively prevents your parts from warping.

Support Removal Stations | EasyWash EW1
You can easily replace the propeller of the EasyWash EW1. Just loosen the screw holding the propeller and carefully remove the old one. Put on the new propeller and tighten it with the screw – it is easy as that! You will find replacement propellers in our Amazon store after the sales-launch of EasyWash EW1.
To solve PVA warm agitated water works best. That said, although we have specially developed the EW1 to work best with VXL support material, it handles PVA pretty well.
We highly recommend to use the basket when dissolving your parts. Not only does it speed up dissolving time, it also keeps you part safe from hitting the propellers. This eventually damages the propeller or your printed part.
How hot can the EW1 heat the fluid inside? How long does it take to reach the temperature? How much power does it draw when keeping the fluid warm?
The EW1 is equipped with a potent heater element. It’s electronically and mechanically limited to a fluid temperature of 85°C. When filled to the max with about 40 Liters, it will reach 85°C in just under 2 hours. When the temperature is reached, power consumption drops significantly. You can find more details on power consumption here after we launched sales on the EasyWash EW1.

Over time, deposits form under the propeller blades. These build-ups can lead to a blockage of the propeller. Occasionally, a piece of a printed part may also get stuck in a propeller and block it. If this occurs, you need to empty the purge bucket. Then, dismount and clean the propellers. This is really easy if you loosen the retaining screw and carefully remove it. Subsequently, clean the propeller and its support and mount the propeller back. You can find more information under in the user manual.
Washing Powder | VXL-EX
As a rule of thumb, you can remember to always use as much VXL-EX as you have printed VXL support material. But alas, as is common with rule of thumbs – be aware of the caveat: The correct amount of VXL-EX in water is 2,4%. Exceeding this by more than 50% may cause unwanted side effects.
VXL EX is comparable to typical household chemicals like washing powder. When dissolved in water, it will have a pH level less than 10,8. Therefore, VXL EX is only marked as “irritant”.
However, even household chemicals like your everyday washing powder should be handled with care. So we advise our customers to use gloves and goggles every time they work with VXL EX.
For more information, please read the safety datasheet of VXL EX.
VXL solve is our dedicated removal agent supplied with our VXL GO Starter kit in small sachets. Need a refill? Get a bottle of our VXL EX. They both work perfectly with our support Materials.
Please keep in mind, VXL Solve may cause eyes and skin irritation. So handle with care!
