Managing CAD files and Creating Them for 3D Printing

Computer-aided design modeling (CAD) refers to the use of 3D models to assess, refine and repeat part design plans. This step takes place before physical production starts. It differs from 3D rendering since CAD modeling is mainly functional. In addition, the 3D CAD model we create often translates into the direct files for 3D printing intended parts. Since CAD models are identical to the final part or product teams and designers can use them to optimize their designs. The 3D CAD models also function to improve design capabilities and aid in streamlining the design validation process. Perfect 3D CAD models often depend on the intent. The part may be intended for engineering and production or may serve as a prototype. Here is further insight into the best practices we use to get the most out of CAD files and how to apply them in 3D printing.

How To Build 3D CAD Models For Rapid Prototype

We use the following CAD optimization methods on most CAD modeling software.

Starting with the Right Technology

Our experts advise that one must first properly pick the right file format needed for the chosen production process. For instance, CNC machining uses a native CAD program along with CAM software or STEP. Meanwhile, 3D printing ideally uses mesh file formats like .3mf and STL. We also consider the baseline computer specifications. A few 3D modeling file formats and tasks and need more or less processing power. By double-checking the CAD modeling software needs, we ensure there is enough computing power and RAM to create top-notch 3D models.

Considering Possible Future Changes via Editing

3D CAD modeling is an awesome way to sample new designs before production. However, changing the part design depends on the file format in use. Another key factor to consider is whether or not there is a need to create a CAD sketch from the 3D CAD model. Native CAD forms such as Creo and SolidWorks are the most editable. We can simply go back and make any changes just like in a word document. In addition, we can make a CAD drawing from the mesh or STL files. These are usually not editable and making changes resemble editing a JPEG. This format does not allow us to create a CAD drawing. To save time, we strive to avoid having to create a new 3D CAD model every time the design changes. We achieve this by choosing a file format that meets the stage of the design process. The mesh files are ideal for the final versions.

Creating a CAD File for 3D Printing

Despite modern advances in the digital era, many manufacturers still support outdated production systems. This is to ensure they can make parts from the past era. This arrangement may end up being a liability in the long term. Product creators end up running the risk of losing valuable operational deficiencies and design data. This is since the tools and software initially in use can sustain the current design demands. Luckily, additive manufacturing has excellent operational efficiency and speed. This makes 3D printing a far more economical production method than previous ones. Creating a computer-aided design also prevents designs from being lost entirely. In addition, if a part needs any update, it far less cost-effective and efficient to develop a design from scratch. By transferring part drawings to CAD files, we end up streamlining the documenting process. It is also easier to implement future updates.

Drawing Conversions

This is a simple process of creating a CAD file from the illustration specs. It applies when you have the technical 2D drawing for a part and is one of the simplest solutions. In the absence of technical drawings, we can use reverse engineering. This process begins by creating a drawing of the part and then use it to create a 3D CAD file. It requires the use of an intact copy of the part that is easy to measure and thus re-creatable as a CAD file. It must have all the specs for the part’s performance features and tolerances.
