Formlabs Alumina 4N Resin Cartridge Form 4, 2 kg 0.78 l

Enter a new era of ceramic manufacturing with Formlabs Alumina 4N Resin Cartridge (Form 4), 2 kg (0.78 l). This groundbreaking material finally makes high-performance ceramic 3D printing affordable and accessible. Designed as a Form X material for skilled users, Alumina 4N Resin empowers you to produce exceptionally pure (99.99%), fully dense technical ceramic parts. Bypass the high costs and long lead times of traditional methods and create components with complex geometries that deliver outstanding performance in extreme thermal, mechanical, and chemical conditions.

Important Storage Information: Alumina 4N Resin has a 3-month shelf life at room temperature. For an extended shelf life of up to 12 additional months, we highly recommend refrigerating the resin at a temperature between -10 and 4 °C.

Unlock the Advantages of In-House Ceramic Printing

Alumina 4N Resin creates parts with a 98.6% relative density and material properties that are comparable to traditionally manufactured alumina (Al2O3), making it a transformative solution for advanced manufacturing.

Affordable Access to Advanced Ceramics

With a startup cost that is over ten times lower than leading alternatives, the Formlabs ceramic 3D printing ecosystem removes the financial barriers to producing high-performance technical ceramics. Take full control of your production by bringing it in-house.

Break Free from Design Constraints

Create ceramic components with complex geometries, such as internal cooling channels and intricate lattice structures, that are impossible to achieve with traditional manufacturing. You can now optimize your part designs for maximum performance without the limitations of molding or CNC machining.

Shorten Production Cycles and Cut Costs

Leave expensive tooling and molds behind. By 3D printing your ceramic parts on-demand, you can significantly reduce production costs, accelerate development cycles, and iterate on new designs more quickly and efficiently than ever before.

Performance in the Harshest Environments

Manufacture parts you can rely on in the most demanding applications. With an impressive maximum working temperature of 1500°C, a flexural strength of over 400 MPa, and a modulus of 380 GPa, your components will reliably resist heat, compression, and deflection.

Ideal for Demanding Industrial Applications

Alumina 4N Resin provides a time and cost-effective method for fabricating high-performance parts destined for extreme environments. Its excellent thermal and electrical insulation, combined with superior chemical and wear resistance, makes it a top choice for the aerospace, manufacturing, automotive, and chemical industries. Common applications include:

• Electrical Insulators: High-voltage connector housings, terminal blocks, and custom enclosures.
• Wear and Chemical Resistant Parts: Tooling, mixing paddles, and pipes for handling abrasive or corrosive materials.
• High-Temperature Fixtures: Insulating tubes, spark plug insulators, and thermal protection mounts.
• Metal Casting and Foundry Tools: Custom crucibles, thermocouple sheaths, filter cores, and casting gates.

A Professional Workflow for Ceramic Parts

As an advanced Form X material, producing parts with Alumina 4N Resin involves a detailed, multi-step process. This guide outlines the key stages for success.

Step 1: Design for Sintering

To compensate for shrinkage during the firing process, you must scale your model in PreForm. Use a scaling factor of 121.5% for the X/Y axes and 126.5% for the Z axis. Review your design to ensure all features adhere to the recommended dimensional guidelines.

Step 2: Print Your Part

Thoroughly shake the resin cartridge for at least one minute before use. Confirm that your build platform, resin tank, and mixer are clean. After sending the scaled file to the printer, you can begin the print job.

Step 3: Wash the Green Part

Using a Form Wash, clean the printed parts with >99% IPA for a total of 20 minutes. This should be done in two 10-minute cycles, using fresh IPA for the second cycle to ensure all residual resin is removed. Carefully detach the parts from the build platform between cycles.

Step 4: Ensure Thorough Drying

Parts must be completely dry before moving to the furnace. Use compressed air to clear any remaining IPA from surfaces and internal channels, then let the parts air dry for a minimum of 30 minutes. A visual inspection should confirm no wet spots remain.

Step 5: Debind and Sinter in a Furnace

This crucial stage requires a furnace capable of reaching at least 1550 °C in a well-ventilated space. Place the dry parts on an alumina setter plate. The furnace will run a debind cycle to slowly burn out the polymer binder, followed by a sinter cycle that heats the part to fuse the ceramic particles into a dense, solid object. This combined process takes over 40 hours.

Step 6: Optional Finishing

Once the part has cooled, supports can be removed with pliers or a rotary tool. For an ultra-smooth finish, the sintered parts can be sanded and polished using diamond-tipped tools and appropriate polishing compounds.
