DIY 3D Printer Frame Kits and Fastening components

Jul 12,2024


One of the most crucial components of a 3D printer is the frame. Although it appears simple, the design can be really complex. The numerous design options are the reason for this. The following reasons explain the importance of the 3D printer frame:

  • It provides support for all the electrical and mechanical parts that actually do the printing.
  • It determines the 3D printer's construction volume.
  • It contributes to both the printer's elegant appearance and robust appearance.

The price, simplicity of assembly, robustness, longevity, and application specifically and the intended build volume, all need to be taken into account when selecting a 3D printer frame. Businesses and designers who wish for their printer to appear professional and appealing to the public may find aesthetics to be quite important. For printers used only for basic prototyping or experimentation, it might not be a problem.

The following is a description of the DIY 3D printer frame types and construction to help you choose the right kind of frame for your own 3D printer:

  • Joint & Member Frame
  • Laser or CNC Cut Frame
  • Metal 3D printer frames

Joint & Member Frame

The most basic and popular construction for a 3D printer frame is called a Joint and Member construction, Fig. 1.  Similar to trusses, structural components can be joined by joints and take the shape of bars or rods. Either threaded rods or extrusion (smooth metal or aluminum rods) are used as the members. The design is easy to create, inexpensive, and basic.

While the frame's low cost and ease of assembly are huge advantages, there are disadvantages to this design as well. The parts of the printer are visible in this frame. Both the printer and the user's safety are put at risk by this. Materials or items may be drawn to the hot end nozzle, and things may clog the belt and pulleys. The frame's appearance is another disadvantage; it is not the most beautiful. For experiments and prototyping, these printers are perfect.

Laser or CNC Cut Frame

Another inexpensive choice for 3D printer frame constructing is a laser or CNC cut frame. Panels are made from materials like plastic, acrylic, or plywood using laser or CNC machining. The panels are then fastened together like a puzzle to create the finished frame structure. Since the parts are cut in two dimensions, no specialized software is needed.

The main benefit of this kind of frame is its simplicity in design and low cost of production. 3D printer frames with laser or CNC cutting have disadvantages just like everything else. The panels' stringent manufacturing tolerances and puzzle-like design make them challenging to assemble. Over time, plywood will warp, particularly when exposed to moisture and high mechanical pressures. Additionally, these frames are prone to scratches, particularly if they are made of plastic or acrylic.

Metal 3D printer frames

You can customize metal 3D printer frames, Fig. 3, but not for home users. Injection molding is used in the production of these frames. Large-scale production of 3D printer frames is made possible by this method. For this reason, high-end clients and the commercial sector are the ideal targets for these metal frames.

This method has the advantages of being robust and usually requiring no setup. The main disadvantage of this method is that it takes additional machining to adapt metal frames over time, which makes it challenging.

There are numerous 3D printer frames on the market, and as was previously mentioned, the selection is based on factors like build volume, durability, and ease of assembly and cost.

A 3D printing toolbox wouldn't be complete without the extra parts required for machine construction, maintenance, and repairs. Metric components are often used in 3D printers; M2 to M10-12 components are used for desktop models. In metric components, the letter "M" stands for a millimeter value connected to the important hardware component. The value is expressed as the width of the hardware's threaded section for nuts and bolts/screws. For instance, the width of an M5 screw post and an M5 hex nut hole are both 5 millimeters. A 3D printer's construction may require hundreds to thousands of screws, bolts, and nuts, depending on its size and complexity. It's much easier to fix or alter a 3D printer when you have extra M3, M4, and M5 fasteners on hand rather than having to go to the store.

Even for completely working devices provided without any accompanying hardware or equipment, matching hex wrenches and socket wrenches are essential for performing operations involving nuts, bolts, and screws in 3D printers. In order to evenly distribute the force of a screw or bolt across the surface of the object they are inserted into, washers are used. Screws without a washer have the potential to apply excessive force to a tiny enough portion of a 3D printed object, particularly in RepRap 3D printers. Additionally, they can aid with component spacing along a bolt or screw, allowing for precise component adjustment. Shims are incredibly thin washers that aid in spacing and allow the user to adjust things. They are not the same as washers and are not intended to disperse the load from fasteners or screws used to provide structural stability.
