Siraya Tech Magna Durable 3d printing Resin User Manual

1. Introduction

Siraya Tech Magna Durable Grey is a versatile, all-purpose engineering resin designed for exceptional performance across a wide range of applications.

Building on a foundation known for stiffness and impact resistance, Magna Durable Grey offers high resolution, outstanding toughness, and ease of printing. Its balanced properties make it an excellent choice for everything from detailed tabletop miniatures and models to robust engineering prototypes and functional parts.

2. Key Features

Versatile All-Purpose Resin: Ideal for miniatures, prototypes, and functional parts.
Exceptional Toughness & Durability: Combines good stiffness with high impact resistance for parts that last.
High Resolution: Capable of capturing fine details suitable for models and intricate designs.
Easy to Print: Formulated for a user-friendly printing experience with good adhesion and success rates.
Fast Printing: Optimized for quicker print times compared to some specialized engineering resins.
Superior Wear Resistance: Suitable for parts requiring durability under use.

3. Printing Preparation

Magna Durable Grey may have a higher viscosity than typical standard resins. Proper preparation is key for successful prints.

3.1 Resin Mixing

Shake the bottle well for at least 1 minute before each use. Magna Durable Grey contains pigments that can settle over time. Ensure the resin is uniformly mixed before pouring.

3.2 Printer Settings & Support

Printer Profiles: Download the latest Magna Durable Grey profile for your specific printer from the Siraya Tech website Print Setting Page

Reference Settings: If your printer isn't listed, you may consult profiles for similar resins but be prepared to adjust settings, especially exposure time (Magna Durable Grey may print faster). Always perform calibration tests.

Key Parameters: Remember that optimal settings involve more than just exposure time; lift speed, retract speed, and light-off delay (wait-after-retraction) are crucial for success with tougher, potentially more viscous resins.

Support Structures: Due to Magna Durable Grey's flexibility in its uncured (green) state, standard supports may be insufficient. It is strongly recommended to use thicker and denser support structures. Using the default "Heavy" support settings in Chitubox or Lychee Slicer is a good starting point. Insufficient supports may lead to print failures or deformation.

3.3 Build Platform and VAT Preparation

Ensure the build platform is level and clean.
Lightly sanding the build platform surface with fine-grit sandpaper can improve first-layer adhesion.
Clean the resin vat thoroughly, ensuring no cured particles or residue from previous prints are present.

3.4 Temperature Considerations

Optimal printing temperature is 25°C (77°F) or higher. Printing below this temperature can increase viscosity significantly and affect print success.

If printing in a cooler environment, consider using a printer enclosure or a small space heater pointed near (not directly at) the printer to maintain a stable, warm temperature.

You can pre-warm the resin bottle by placing it in a bath of warm (not hot) water (around 40°C) for 10-15 minutes before shaking and pouring.

4. Printing Process

Pouring: After shaking well, pour the resin into the vat carefully to minimize bubble formation.

Bubbles: If bubbles are present, you can let the resin sit for 5-10 minutes in the vat before printing to allow them to rise and pop. Gently using a silicone spatula can help.

Settling Time: Allow the resin to settle for a few minutes before starting the print.

Monitoring: Monitor the first few layers closely to ensure proper adhesion to the build platform.

High Viscosity Resin Printing Note:

Some printers may have issues with the build platform pressing down fully for the first layer:

This may trigger sensor alerts in Saturn 3/4 Ultra and other newer printers. You can bypass the warning and begin printing if an alert appears.

If the printer refuses to start, try beginning the print with only a very thin layer of resin in the vat, then add more resin once the build plate is down during the first layer's exposure.

5. Cleaning

Thorough cleaning is essential for achieving the best final properties and surface finish.

Draining	After printing, let the part drain thoroughly over the vat for at least 10 minutes.
Washing	Ultrasonic: An ultrasonic cleaner with 90% or higher concentrated Ethanol or IPA for 5-10 minutes is effective. Manual: If cleaning manually, use two washes: the first to remove most resin, the second with cleaner alcohol to finish.	Ensure the cleaning agent is not too cold, as this reduces efficiency.
Drying	After cleaning, use compressed air or a hairdryer on a cool setting to completely dry the part, paying attention to crevices and hollow areas.	Using a dedicated drying device (like a food dehydrator set to ~45°C for 30 minutes) can help ensure all solvent evaporates.
Check Surface	Before post-curing, touch the surface (with gloves). If it feels sticky or tacky, the part is not clean or dry enough. Repeat cleaning and drying.

6. Post-Curing

Proper post-curing is crucial for achieving Magna Durable Grey's final mechanical properties.

Prerequisite	Ensure the part is completely clean and dry before curing.	Trapped solvent or surface residue can inhibit curing and lead to a weak or sticky final part.
UV Source	Use a UV curing station or lamp emitting a wavelength of 395-405nm.	Light sources below 395nm will cause the model to yellow quickly and may also cause incomplete curing.
Curing Time	Cure for approximately 10-15 minutes, rotating the part periodically (e.g., every 5 minutes) to ensure even exposure on all surfaces.	Cure time may vary based on the curing unit's power and the part's geometry.
Optional Underwater Curing	You can submerge prints in a transparent water container during UV exposure for potentially faster and more uniform curing.	This helps dissipate heat and blocks oxygen, which can inhibit surface cure.

7. Safety Precautions

Always wear appropriate Personal Protective Equipment (PPE): nitrile gloves, safety glasses, and a respirator rated for organic vapors when handling uncured resin.
Work in a well-ventilated area.
Avoid direct skin contact with uncured resin. If contact occurs, wash the affected area immediately and thoroughly with soap and water. Do not use solvents to clean resin from skin.
Keep uncured resin away from children and pets.
Dispose of uncured resin, contaminated cleaning solutions, and resin-soaked materials (gloves, paper towels) according to your local environmental regulations.
Do not pour liquid resin down the drain.

8. Storage

Store Magna Durable resin in its original opaque bottle in a cool, dark, dry place, away from direct sunlight and heat sources.
Recommended storage temperature is typically 15-25°C.
Keep the bottle tightly sealed when not in use.
Ensure the resin is used within its recommended shelf life for optimal performance.
