Filament dryer DRYCON

Product overview
The BigRep DRYCON is a dual-chamber industrial filament dry cabinet combining three functions: drying, high-capacity storage, and annealing to maximize part quality, strength and thermal resistance. Engineered as a printer companion with direct filament outlets to feed 3D printers and independent chamber control for simultaneous workflows.

Key functions

• Dry: Periodic active air exchange cycles replace humid air with fresh air to eliminate moisture efficiently and provide consistent drying while saving energy.
• Store: High-capacity, climate-controlled filament storage that locks out moisture and heat so material is ready for print.
• Anneal: Bottom chamber doubles as an annealing oven (heats up to 180°C) to relieve internal stresses, improve inter-layer bonding, dimensional stability, heat resistance and mechanical properties of printed parts.

Highlights and performance details

• Dual independent chambers (each chamber 780 x 455 x 410 mm) with customizable temperature settings; upper chamber dries/stores up to 120°C, lower chamber can heat to 180°C for annealing.
• Active air exchange system (periodic air cycles) to remove moisture and ensure uniform drying conditions.
• Integrated Siemens LOGO! control system providing an intuitive user interface.
• Direct dryer-to-printer filament feed system with four filament outlets to streamline printing workflow and eliminate manual filament transfers.

Storage capacities (as presented on the page)
The site provides multiple capacity descriptions; summarized here to preserve all reported values:

Per chamber (table): 12 spools of 0.75 kg OR 8 spools of 4.5 kg OR 4 spools of 8 kg
Together (two chambers combined, page text): up to 24 spools of 0.75 kg OR 16 spools of 4.5 kg OR 8 spools of 8 kg (chambers can be configured independently)
Hotspot mention (combined weight basis): Up to 36 kg filament storage (example configurations shown like 16 x 1 kg, 8 x 4.5 kg, 4 x 8 kg per combined chambers in specific messaging)

Why dry & anneal filaments and parts

• Drying eliminates moisture-related print defects (bubbling, stringing, inconsistent flow) and improves surface finish and dimensional accuracy.
• Annealing rearranges internal structure, releases stresses, improves inter-layer bonding and tensile strength, and increases thermal stability and long-term durability.
