Sculpting, or organic modeling, is mainly used for creating freeform surfaces with intricate details such as characters, jewelry or organic shapes found in nature.

CAD software can simulate a wide range of parameters, including strength or temperature resistance before any physical models have been created. Using CAD software enables you to work faster and more cost-efficiently, without compromising on the quality of your components.

Made for cleaning up stray polish or creating straight lines and edges, the Clean Up Brush is a must-have for any at-home mani moment.

While Protolabs Network can provide DFM analysis on your CAD files and technical drawings, we can't create digital models for you based on drawings of your part or physical components.

Another advantage of solid modeling is that it’s usually parametric, meaning that changes or parameters are saved at every stage of the modeling process and can be edited at any time. This allows features of the model to be quickly modified without needing to create the part from scratch.

Surface modeling is usually used for more aesthetic features of a product. It is much easier to create more organic and free-form geometry using this type of CAD software. Many of the constraints found in solid modeling are not an issue with surface modeling, however, this comes at a cost of sometimes being less accurate.

Assembly modeling is an important stage in solid modeling, allowing individual parts to be assembled together, forming complex models. Assemblies can be used to insert standard components such as fasteners or bearings, that have been downloaded directly from the manufacturers. Motion elements can also be applied to assemblies, allowing detailed motion analysis to be used to evaluate the mechanical performance of the design.

Design for manufacturing (DFM) means taking a design-first approach to manufacturing. In this article, we look at the overall DFM process, the necessary steps for a successful outcome, examples of DFM done right and how to get the most out of your own processes.

As the name suggests surface modeling only deals with the surfaces of the part, with no solid interior. However, once the part has enough surfaces to close the part, it can be filled and then used for 3D printing. When developing designs using surface modeling, it can be hard to go back and make changes because usually, it’s not parametric.

Aside from these two, another viable software is nTopology. Targeted more toward academic and professional users, it lets you create design processes instead of building up objects from scratch, which makes optimizing your parts that much more efficient.

If you don’t have access to more pricey enterprise software for CAD modeling, you can use free options like Fusion 360 and SketchUp Free.

The survey found that the majority of engineers and designers use Solidworks for CAD design. Engineers tended to prefer AutoCAD, Inventor and Fusion 360 (the only free professional CAD software package on the list), while Rhino proved to be the second most popular modeling tool for designers. Interestingly enough, Rhino did not appear on the list for engineers even though it ranked highly for designers.

In developing this article, we sent a survey to over 750 designers and engineers who’ve used Protolabs Network to see which CAD software they prefer. Let’s explore the results.Â

The most powerful software for 3D printing you’re likely to find is Autodesk Fusion 360, which makes it a preferred choice for designers, engineers and architects. It’s ideal for designing and producing very efficient mechanical components, to name one of its many benefits. You also have AutoCAD, the industry mainstay used by engineers and designers across nearly every industry.

CAD (Computer Aided Design), also called 3D modeling, allows engineers and designers to build realistic computer models of parts and assemblies for complex simulations and digital manufacturing. Models created with CAD can be produced as physical components with 3D printing, CNC machining and injection molding.Â

Rapid prototyping uses 3D computer-aided design (CAD) and manufacturing processes to quickly develop 3D parts or assemblies for research and development and/or product testing.

Solid modeling creates solid 3D models as if they are actual parts, with a logical workflow that’s similar to the processes which would be used to manufacture the part. Some of these operations include extruding, drilling and threading. Solid models can intersect, join and subtract objects from one another to create the desired part.

Sculpting software packages such as Pixologic’s ZBrush or Autodesk’s Mudbox were designed with classical sculpting in mind. They allow digital sculptors to start from a simulated ball of clay and use a pressure-sensitive drawing tablet or monitor to manipulate their object with brushes that reflect classic sculpting tools for moving, adding or removing material from their object.
