WHY CONTROLLED DRY STORAGE MATTERS

Hygroscopic materials can absorb moisture from ambient air

Many 3D printing filaments, polymer materials and selected research powders absorb moisture during transport, storage and handling. Depending on the material and process, absorbed moisture can influence extrusion behaviour, material flow, dimensional stability, surface quality and process repeatability.

MOISTURE-RELATED EFFECTS

What uncontrolled humidity can influence

The effect depends on the material, storage duration, packaging and manufacturing process.

Bubbles and surface defects

Moisture may vaporise during processing and contribute to bubbles, rough surfaces or visible printing defects.

Inconsistent extrusion

Moisture can influence extrusion stability, stringing and the repeatability of printed parts.

Clumping and flow changes

Selected powders and granulates may clump or show altered handling and flow behaviour after moisture exposure.

Storage variability

Materials stored under different ambient conditions may produce less consistent testing and production results.

TYPICAL STORED MATERIALS

APPLICATION OVERVIEW

Typical materials, risks and storage considerations

Material group	Moisture-related concern	How controlled storage helps	Important review point
3D printing filaments	Moisture absorption, unstable extrusion, bubbles, stringing and inconsistent print quality	Helps reduce further moisture uptake between printing operations	Follow the filament manufacturer’s pre-drying and storage instructions
Selected powders	Clumping, altered flowability and changes in processing behaviour	Provides an enclosed, controlled low-humidity storage environment	Powder properties, packaging, dust risk and SDS must be reviewed
Pellets and granulates	Moisture uptake before extrusion, moulding or material testing	Supports more consistent conditions between preparation and use	Already wet material may still require pre-drying
R&D samples	Variable storage conditions between tests and development activities	Helps maintain more repeatable storage conditions for suitable samples	Material compatibility and safety classification must be confirmed

MATERIAL HANDLING WORKFLOW

Use controlled dry storage throughout the material lifecycle

Receiving

Review packaging condition, material information and storage requirements.

Preparation

Pre-dry material where required by the material manufacturer.

Controlled storage

Store suitable material in McDry between handling and processing.

Printing or testing

Remove only the quantity required and return remaining material promptly.

WHY MCDRY

Controlled low-humidity storage without continuous nitrogen consumption

McDry uses a zeolite-based drying unit to maintain a controlled dry environment. Depending on the selected model, storage conditions down to 1% RH are available. Standard operation does not require a continuous nitrogen supply.

Ultra-low-humidity storage

Selected models provide controlled storage down to 1% RH.

No continuous nitrogen supply

Standard operation uses an electric zeolite-based dry unit.

Service-friendly design

The humidity meter and dry unit can be handled separately when service is required.

European support

SSG provides product selection, quotations, service and spare-parts support.

Two-year SSG warranty

Cabinets supplied by SSG are generally covered for two years from the SSG shipment date.

CABINET SELECTION

Select the McDry series according to volume and access needs

MCU

Compact storage

Suitable for laboratories, development areas and smaller quantities of filament or research materials.

Space-saving cabinet sizes
Small-volume storage
Laboratory and prototype areas

General-purpose storage

Suitable for regular production and laboratory storage with moderate access frequency.

Large storage capacity
Cost-effective configuration
Long-term material storage

DXU

Frequent-access storage

Suitable for larger quantities and workflows where cabinet doors are opened more frequently.

Rapid humidity recovery
Large-volume storage
Production environments

Final model selection depends on target humidity, material quantity, package dimensions, access frequency and available installation space.

MATERIAL AND SAFETY REVIEW

McDry is not a hazardous-chemical or flammable-material storage cabinet

Suitability must be evaluated according to the material, packaging, process, required humidity, stored quantity and safety classification. Wet, volatile, flammable, explosive, reactive or otherwise hazardous substances must not be stored without prior technical and safety review. Please provide the relevant Safety Data Sheet where applicable.

FREQUENTLY ASKED QUESTIONS

Dry storage for 3D printing and research materials

Can McDry store all 3D printing filaments?

McDry may be suitable for many hygroscopic filaments, but the required storage humidity depends on the polymer grade, packaging, process and material manufacturer’s recommendations.

Does McDry dry filament that is already wet?

McDry is primarily designed to maintain controlled dry storage and reduce further moisture absorption. Material that has already absorbed excessive moisture may still require pre-drying according to the manufacturer’s instructions.

Can powders be stored in a McDry cabinet?

Selected non-hazardous powders may be suitable when stored in appropriate closed packaging or containers. Powder properties, quantity, dust behaviour, packaging and safety information must be reviewed first.

Can flammable or volatile chemicals be stored in McDry?

McDry is not a certified hazardous-chemical, flammable-material, explosion-proof or ventilated safety cabinet. Such materials must not be stored without prior technical and safety review.

Does McDry require nitrogen?

Standard McDry operation does not require a continuous nitrogen supply. The cabinet uses an electric zeolite-based drying unit.

What information is required for model selection?

Please provide the material name, Safety Data Sheet where applicable, packaging type, storage quantity, target humidity, access frequency and available installation space.
