PrintDry has launched their latest 3D printer filament drying system, the PRO4.
The company has been making inexpensive desktop filament drying systems for quite a few years now, starting with a very basic system that somewhat resembled a food dryer.
Nowadays, they are well beyond that stage with the PRO4, which indeed does have a number of professional features.
The PRO4 is a modular system that can be expanded by adding more modules. This allows you, for example, to dry more spools simultaneously, or accommodate larger spools up to 5kg.
The main feature is that this inexpensive drying system can handle heat as high as 85°C. That’s in the range where you can effectively dry higher temperature engineering filaments like nylon or PVC.
The PRO4 also features, for the first time in PrintDry products, a real-time humidity monitor. There, you will be able to see the relative humidity drop as the PRO4 does its work.
They’ve also improved the heating system on the PRO4, and it appears quite effective. The double-walled sides are more capable of holding in that heat. They write:
“During our tests, the chamber humidity drops from over 60% to below 15% in just under FIVE minutes, giving you the instant feedback and confidence.”
That’s pretty impressive, as some other dryers I’ve used take quite a while to lower the humidity.
They’ve also redesigned the airflow so that it is able to provide a more even flow through the chamber.
I should mention that the PRO4 is also able to feed filament directly to your 3D printer through conveniently located ports on the front of the system. That way, the freshly dried filament stays dry during print jobs.
The PRO4 is now available for order on Kickstarter, with prices starting at CA$279 (US205) for the base unit, and CA$299 (US$220) for the large spool bundle.
