Explore the materials behind ExtruFrame, then choose how to own it: 3MF digital files for your own workshop, or a physical case made by us.
Buy the 3MF digital files, make the parts on your own 3D printer and assemble your ExtruFrame. Choose your material, configure your modules and bring your own finish to the build.
Buy the physical ExtruFrame case made by us. Select your model and available modules, then build your PC around it. Get the same modular design without making the case parts yourself.
A material-level illustration using a PETG-CF reference grade and industrial EN AW-6060 aluminum. Compare equal solid volumes, then explore how the manufacturing routes differ.
Calculated mass = density × solid material volume. The 54% figure is rounded from 53.7%. This is not a complete-case weight saving or an equal-strength comparison.
3D printing makes it practical to create shaped surfaces, ribs and customized modules without machining each feature out of a metal billet.
Carbon-fiber-filled PETG is a functional engineering material, chosen for a rigid, practical composite structure. ExtruFrame brings that material together with shaped sections, controlled printing and modular connections.
Conceptual section · design principles, not a load-test result
Carbon-fiber reinforcement can improve PETG stiffness, supporting crisp, stable functional parts. The selected grade and print direction determine the actual mechanical properties.
Walls, ribs and connection points shape how a component carries load. Design-led geometry gives us freedom to put structure where the design needs it.
The modular approach makes individual components replaceable. A changed panel or damaged module does not have to mean replacing the whole case.
The polymer composite does not form the iron rust associated with steel. The manufactured component’s rust resistance does not rely on a painted metal surface.
Applies to the polymer composite parts; metal fasteners and PC hardware have their own material requirements.PETG is widely used for mechanical parts and fixtures. The CF-filled formulation brings a stiffness-focused material option to the case’s structural design.
Finished-part performance follows the exact grade, geometry, layer bonding and assembly.Change the armor, adjust the accessory layout or print a new module. Maintainability comes from accessible parts and a design that can evolve with your hardware.
Compatible part files and assembly details will be specified with the campaign.“Rust-resistant” is not a claim of immunity to every chemical or environment. Cleaning-agent compatibility, heat exposure and long-term loading depend on the chosen filament and component.
PETG-CF is not advertised here as an electrical insulator or an ESD-safe material. Carbon filling can alter electrical behavior, and static dissipation requires a suitable grade with measured properties. Use the intended motherboard standoffs, mounting clearances and component handling practices.
For configurable, complex parts in small runs, printing can reduce machining setup and make customization more accessible. Final price depends on the actual configuration.
Selected editable STP components give you a starting point for custom front panels, patterns and PSU covers.
Produce a replacement or a different component when you change the build, rather than replacing the entire case.
PETG-CF density: 1.25 g/cm³, using Bambu Lab’s published grade as a reference, not a commitment to a specific production supplier. Aluminum: 2.70 g/cm³, Hydro EN AW-6060. Actual filament grades differ.
Density is the only material property plotted. Aluminum has substantially higher material stiffness and heat tolerance; manufactured-part behavior also depends on orientation, layer bonding, geometry and loading. These graphics do not establish equivalent strength, stiffness or thermal performance. Cost benefits are a production rationale, not a measured price-reduction claim.
PETG-CF is our default. ASA-CF, ABS-GF, PET-CF, PPS-CF and other engineering materials can be considered by request. Match the grade to the part’s load, environment, printing process and budget.
Our starting point for the case components: carbon-fiber-filled PETG with a technical surface character and a balance of rigidity, everyday practicality and manufacturing cost.
The default ExtruFrame material. Exact filament grade and component print settings determine the finished properties.An alternative for builds where weathering and UV exposure are part of the material brief. Carbon-filled ASA offers a different balance of surface finish, stiffness and processing requirements.
Match the actual grade to the application; enclosure and thermal-control requirements depend on the filament.Glass-fiber-filled ABS is another engineering-material route for selected parts. It offers a different reinforcement system for customers choosing materials around a specific mechanical or thermal requirement.
Use the supplier’s technical data and process guidance. GF indicates glass fiber, rather than carbon fiber.A carbon-fiber-filled PET option for an engineering-focused material specification. It expands the choices available when PETG-CF is not the preferred match for a component.
PET-CF and PETG-CF are distinct materials. Drying, printing and any post-processing must follow the selected grade.For demanding engineering briefs, carbon-fiber-filled PPS brings a specialist material route. It requires a printer and process suited to the particular high-temperature filament.
Not an entry-level desktop-filament substitution. Confirm equipment capability, material handling and production feasibility first.The MakerWorld campaign is for builders who want to print their own parts. Check the campaign’s file contents, component sizes and assembly requirements before starting.
Decide which frame you want to build, then select the cooling, armor and optional SKÅDIS pegboard modules. Print the components for your chosen setup rather than assuming every optional part is required.
Start from the PETG-CF material brief, or select another suitable engineering grade. Check nozzle wear resistance, filament drying, bed and nozzle temperatures, enclosure needs and ventilation against the filament supplier’s guidance.
Part orientation, layer bonding, walls and local reinforcement influence the result. Follow the released part-specific instructions when available; do not substitute a decorative print preset for a structural component.
Check mounting interfaces and hardware fit before final assembly. Use the specified fasteners and any inserts identified in the build documentation. Review custom STP edits for changes to clearances and structural sections.
Carbon and glass-filled filaments are abrasive; specialist materials such as PPS-CF also require appropriate equipment and handling. See Prusa’s composite-material guide and the PPS-CF supplier guidance.
