3D Hubs is the world's leading provider of 3D printing, CNC machining, sheet metal fabrication, and injection molding services. Engineers who use the 3D Hubs online manufacturing platform can access a free DFM analysis and generate an instant quote for their chosen manufacturing method.

Design for manufacturing (DFM) is a philosophy used to create viable designs that are easy to manufacture. DFM is particularly important for sheet metal fabrication, where small design flaws could result in cracks, tears, or unwanted bends in the metal. Following these essential DFM guidelines will result in parts that are strong, durable, and identical to engineering specifications.

Sheet metal fabrication is just one of the many online manufacturing processes offered by online manufacturing shops. Before you order your part, make sure that you've selected the most efficient way to create that item.

Sheet metal parts are created by bending or cutting a sheet of metal which is usually no more than 6 millimeters thick. This process is well-suited for creating large, flat, or hollow metal parts. Soda cans, metal boxes, car doors, and similar structures are all made with sheet metal fabrication.

Sheet metal fabrication is not a good choice for three-dimensional objects with complex geometries. If the object is significantly thicker than a piece of sheet metal, has many fine details, or would require significant bending or sculpting to reach the desired shape, engineers should choose another manufacturing process instead.

CNC machining is a popular manufacturing choice that allows engineers to work with metal bars in different shapes and sizes. 3D printing can be used to create complex geometries out a variety of materials ranging from thermoplastics to metal. When large batches of identical parts are needed, injection molding services are almost always the most affordable option.

When uploading a design, engineers can compare all of these different manufacturing methods. The automatic DfM analysis will check the viability of the design against each chosen process, and engineers can choose the one that works for their part while meeting budget requirements.

Design for manufacturing (DFM) is an engineering philosophy that takes the limits of current manufacturing capabilities into account. Shapes that might be very easy to design in a CAD program aren't always possible to create with the chosen manufacturing process. Engineers should be aware of the specific tools that are available and the way that the material will react when those tools are applied.

No matter which manufacturing process you choose, there are several guidelines that are an essential part of DFM philosophy.

In addition to these universal DFM principles, there are several specific guidelines that need to be followed when working with sheet metal. The thickness of the sheet metal is frequently taken into consideration.

After creating a part based on these DFM specifications, engineers should upload their design to the online manufacturing platform for a free DFM analysis. The intelligent software will automatically compare the CAD file to the requirements of the chosen manufacturing method, and any issues will be flagged for review or correction.
