Many builders choose the FolgerTech FT\u20115 for its open-source frame and large build volume. But confusion often arises around its extrusion sizes. Knowing the exact profiles used in its frame helps avoid mistakes during upgrades or rebuilds.<\/p>\n

The FT\u20115 uses 2020 (20\u00d720\u202fmm) and 2040 (20\u00d740\u202fmm) aluminum extrusions in its frame. These are standard T\u2011slot profiles, offering a lightweight but rigid structure for 3D printing.<\/strong><\/p>\n

If you’re thinking of modifying, replacing, or improving the frame, read on to learn which profiles are used, why they were chosen, how to ensure compatibility, and what options exist for stronger upgrades.<\/p>\n

\n

What extrusion specs fit the FT\u20115?<\/h2>\n

The FT\u20115 kit comes with a mix of 2020 and 2040 aluminum extrusions, both in metric T\u2011slot format.<\/p>\n

FT\u20115 uses 2020 extrusions for vertical and gantry structures, and 2040 extrusions for the base and bed support \u2014 providing strength where needed without adding unnecessary bulk.<\/strong><\/p>\n

According to the official FT\u20115 assembly guide, the typical profile breakdown looks like this:<\/p>\n\n\n\n\n\n\n
Perfil<\/th>\nDimensiones (mm)<\/th>\nUso t\u00edpico<\/th>\n<\/tr>\n<\/thead>\n
2020<\/td>\n20 \u00d7 20<\/td>\nUprights, gantry supports, frame edges<\/td>\n<\/tr>\n
2040<\/td>\n20 \u00d7 40<\/td>\nBase structure, bed frame<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

All profiles are standard aluminum T\u2011slot. This allows you to attach linear rails, motors, brackets, and plates using T\u2011slot nuts and M5 bolts. The slots make it modular and easy to customize.<\/p>\n

Because 2020 is lighter, it’s used where rigidity isn’t as critical. 2040 adds strength at the base where bed weight and motion stress are higher.<\/p>\n

\n

Why printer frames use specific sizes?<\/h2>\n

The FT\u20115 uses moderate-size extrusions not because they’re the strongest, but because they match the printer’s needs for rigidity, cost, and ease of use.<\/p>\n

Printer frames like the FT\u20115 use 2020 and 2040 extrusions to strike a balance between structural stability and lightweight modular design.<\/strong><\/p>\n

\"Industria
Industria de la extrusi\u00f3n de aluminio<\/figcaption><\/figure>\n<\/p>\n

Extrusion profiles define the mechanical backbone of a printer. But using the strongest profile doesn\u2019t always mean better printing.<\/p>\n

    \n
  • 2020<\/strong> provides enough stiffness for vertical members and moving gantry assemblies.<\/li>\n
  • 2040<\/strong> reinforces the bottom structure to handle the heated bed and Y-axis motion.<\/li>\n<\/ul>\n

    These profiles are also widely available, cheap, and compatible with countless brackets, braces, and mounts. This means fewer custom parts are needed, and repairs or upgrades are easier.<\/p>\n

    Lightweight extrusions reduce overall weight, making it easier to move the printer, and place it on typical desks or workbenches.<\/p>\n

    For most plastic-printing loads, 2020\/2040 profiles are strong enough. Overbuilding with 4040 or 4080 extrusions adds weight and cost, but brings little benefit unless the printer is modified for high-speed or heavy-load use.<\/p>\n

    <\/svg> The FT\u20115 frame uses 2020 and 2040 extrusions for a practical mix of rigidity and lightweight construction.<\/b>Verdadero<\/span><\/p>

    These sizes are ideal for 3D printers with moderate loads and allow for flexible assembly.<\/p><\/div>\n

    <\/svg> 3D printers always use large 4040 extrusions to avoid vibration.<\/b>Falso<\/span><\/p>

    Smaller profiles like 2020 are sufficient for most desktop 3D printers and are standard in many kits.<\/p><\/div>\n

    \n

    How to verify frame compatibility?<\/h2>\n

    Upgrading or rebuilding a printer frame means checking that all dimensions and hardware will still fit the structure.<\/p>\n

    You verify frame compatibility by comparing slot spacing, mounting hole positions, extrusion dimensions, and ensuring the new frame fits your printer\u2019s build area and motion hardware.<\/strong><\/p>\n

    \"Art\u00edculo
    Art\u00edculo Extrusiones de aluminio estructural<\/figcaption><\/figure>\n<\/p>\n

    Here\u2019s how to do that:<\/p>\n

      \n
    1. Measure extrusion dimensions<\/strong> \u2013 Confirm that replacement extrusions match the length and profile dimensions of the original.<\/li>\n
    2. Check slot position<\/strong> \u2013 Different profiles (like 2020 vs 2040) have slots in different places. If mounting brackets expect a certain slot location, mismatch can happen.<\/li>\n
    3. Compare bolt and bracket fit<\/strong> \u2013 Standard T\u2011slot accessories work with 6 mm or 5 mm slots; confirm you use matching nuts and bolts.<\/li>\n
    4. Measure internal dimensions<\/strong> \u2013 Swapping a 2020 beam for a 4040 beam will reduce internal space unless you adjust other parts.<\/li>\n
    5. Test linear rail alignment<\/strong> \u2013 If rails or belts are offset, extrusion size affects their height and placement. Ensure motion systems stay aligned.<\/li>\n<\/ol>\n

      If you\u2019re keeping the bed size (300\u00d7300 mm), verify that the gantry, belts, and endstops still line up after any frame size change.<\/p>\n

      <\/svg> Changing extrusion sizes requires checking that bed clearance and part alignment remain correct.<\/b>Verdadero<\/span><\/p>

      Larger or smaller extrusions affect internal dimensions and motion geometry.<\/p><\/div>\n

      <\/svg> All extrusions have identical slot geometry, so compatibility is never a concern.<\/b>Falso<\/span><\/p>

      Slot size and spacing vary by profile; hardware must match to avoid misalignment.<\/p><\/div>\n

      \n

      Can upgrades change extrusion size?<\/h2>\n

      Yes \u2014 some builders upgrade FT\u20115 frames to 3030, 4040, or even 4080 profiles for added rigidity. But it\u2019s not plug-and-play.<\/p>\n

      You can upgrade extrusion size for added strength, but this requires reconfiguring mounting brackets, motion system placement, and overall frame alignment.<\/strong><\/p>\n

      Reasons to upgrade include:<\/p>\n

        \n
      • Reducing flex for tall prints or high-speed printing<\/li>\n
      • Supporting heavier beds (e.g. aluminum or glass platforms)<\/li>\n
      • Preparing the printer for enclosed builds or multi-head systems<\/li>\n<\/ul>\n

        But larger extrusions affect more than just strength:<\/p>\n

          \n
        • Increased footprint<\/strong> \u2013 larger beams take more space, reducing internal clearance.<\/li>\n
        • Changed mounting height<\/strong> \u2013 rails, brackets, pulleys may no longer align without shims or repositioning.<\/li>\n
        • Cost and weight<\/strong> \u2013 larger profiles cost more and add significant weight.<\/li>\n<\/ul>\n

          You may also need new brackets or printed parts. Pre-drilled parts sized for 2020\/2040 may not fit 4040 profiles without rework.<\/p>\n

          Some users instead opt for reinforcements<\/strong> rather than a full profile swap. For example:<\/p>\n

            \n
          • Adding diagonal braces<\/li>\n
          • Using aluminum plate on vertical supports<\/li>\n
          • Bolting two 2020 profiles together for a wider beam<\/li>\n<\/ul>\n

            These keep compatibility and offer improved stiffness without total redesign.<\/p>\n

            <\/svg> You can upgrade an FT\u20115 frame to larger extrusions, but it requires adjusting part fit and frame spacing.<\/b>Verdadero<\/span><\/p>

            Changing profile sizes impacts component alignment and frame geometry, requiring reconfiguration.<\/p><\/div>\n

            <\/svg> Upgrading extrusion size can be done without changing any brackets or mounting hardware.<\/b>Falso<\/span><\/p>

            Larger profiles shift mounting points, requiring new brackets or modifications to fit properly.<\/p><\/div>\n

            Conclusi\u00f3n<\/h2>\n

            The FolgerTech FT\u20115 uses a smart combination of 2020 and 2040 aluminum extrusions \u2014 enough to deliver reliable prints, yet light and modular for home builders. Knowing the correct extrusion size helps when replacing, upgrading, or expanding the frame. If you aim for more strength, you can move to bigger profiles, but it comes with changes in alignment and structure. With the right planning, even a 2020-based frame can support a solid, large-format 3D printer.<\/p>","protected":false},"excerpt":{"rendered":"
