Drying Cabinet up to 40 spools 130°C

Protype FILO
Industrial Drying Cabinet

Consistent print quality starts with dry filament. Up to 40 spools, temperature up to 130 °C, humidity <0.1% RH, connection to 3 printers.

Problem

Why you need a drying cabinet:
moisture destroys prints

Polymer filaments are hygroscopic. Moisture in the material leads to bubbles, delamination, loss of strength, and defects. Especially critical for PA, PC, PEEK, TPU.

−40% strength

Wet nylon loses up to 40% of its mechanical strength. Parts become brittle and unpredictable.

8–10% defect rate

Average defect rate in production without filament moisture control. Excess material and time consumption.

24 hours

Filament absorbs a critical amount of moisture within a day. PA-6 gains up to 9% moisture without protection.

Conclusion: without industrial drying, it is impossible to guarantee consistent print quality with engineering and high-temperature polymers.

Visual Evidence

What happens to a part
without filament drying

Wet material causes bubbles, roughness, delamination, and loss of geometry. Same model — two different results.

Surface roughness

Surface roughness

Bubbles and foaming due to moisture evaporation during extrusion

Layer delamination

Layer delamination

Weak interlayer adhesion — part delaminates under load

DRY vs WET filament

Dry vs wet filament

Same model, same printer — the only difference is material preparation

How It Works

How FILO works

Four steps from wet filament to consistent printing

01
Load Spools
4 shelves — up to 40 spools. Quick replacement without tools.
→
02
Set Temperature
PID controller precisely maintains the set temperature from 40 to 130 °C.
→
03
Automatic Drying
Closed-loop system with silica gel reduces humidity to <0.1% RH.
→
04
Feed to Printer
Dry filament is fed directly to CD400/CD400HT through a sealed channel.

Closed-loop system: silica gel absorbs moisture from the air inside the chamber. Desiccant regeneration occurs automatically during heating. No consumables — only electricity.

Interface

FILOTouch — one-touch control

Built-in touchscreen display for full control over the drying process. Real-time temperature and humidity monitoring, ready-made profiles for all materials.

Ecosystem

Unified management via Protype Hub

FILO integrates with Protype CD400 and CD400HT printers via Protype Hub. All drying parameters are visible on the printer screen.

  • Real-time temperature — current and target FILO chamber temperature on the printer touchscreen
  • Humidity level — RH sensor shows material readiness for printing
  • Drying status — time to readiness, current drying cycle
  • Notifications — automatic notification when material is ready for printing

Unified interface

Protype Hub combines the printer and drying cabinet into one system. The operator sees all data on a single 22" screen.

Drying data

Drying data is stored in the printer log. Full traceability of the material preparation process.

ROI

Payback in 3–4 months

Without industrial drying, a facility loses 8–10% of material and time on each batch

8–10%

Losses without drying

Defects, reprinting, material write-off. For every 100 kg of filament — up to 10 kg wasted.

3–4

Months to payback

When using 2+ printers and consuming 30+ kg/month of engineering materials.

24/7

Continuous operation

FILO operates around the clock, providing dry filament for 3 printers without operator intervention.

Without FILO

✕ 8–10% defect rate on hygroscopic materials ✕ Manual drying in ovens — inconsistent results ✕ Printer downtime for wet spool replacement ✕ Up to 40% loss of part strength

With FILO

✓ Defect rate <2% — consistent print quality ✓ Automatic drying of up to 40 spools simultaneously ✓ Continuous feed to 3 printers ✓ Full material strength, repeatability
