Advancing From Digital To Physical In 3 Simple Steps

Advancing From Digital To Physical In 3 Simple Steps

CAD Design

Before the widespread adoption of additive manufacturing, CNC machining, rapid prototyping techniques, hardware design, and product design iteration were usually sluggish at best. It is because of the many phases of conventional product development. Before the digital age, scientists and engineers will first write/draw out the design or idea on paper, propose several hypotheses, research the best-fit materials and then build the product. In the cases of errors and failures, the consequences were painstaking and arduous; the engineers will need to return to square one, investigate and retry.

Why Digital Iteration is never enough

Many newbie product developers often drag their design iteration and spend ample time in the digital phase. For many, this is where the purse of perfection must attain. Sadly, this is not the case. Unless your product is an electronic concept that will be used intangibly, digital iteration can never be enough. Here’s why:

Each phase informs the other – the feedbacks from physical versions will be put into improving the digital concept.

Scale does matter – digital iteration may be scaled down some percentage of the original size. Having a physical version will inform the spatial relationships, putting the bigger picture in view.

Evaluating functionality – do the parts function as they should? Do they fit into one another? does the chosen form enhance how the product performs and behaves?

Sense organs – physical iterations can help you see, feel and even smell what the product is like. You also get to understand how texture plays a role in the product’s usability.

Making the Shift

1. Ready your digital file

The chosen production method will determine the type of digital file you have. For rapid prototyping, CNC machining and 3D printing are most common. For 3D printing, you should have an STL file. STEP files are most common for general manufacturing. You may also have a CAD or CAM file for CNC-ers. Whatever the case may be, ensure that you have properly formatted and saved the file appropriately, as it is not uncommon to have errors in digital files when converting.

2. Note the version

Now that the digital file is ready, save the file while documenting the version in the document properties. Assigning a version to a file helps keep track of what is in that build, the modifications to be or that have been made from the previous version.

Versioning also allows you to compare new iterations with previous designs should the need arise.

3. Manufacture physical prototypes

Lastly, send the most recent version of your digital file to your team members, manufacturing partner, and supplier for inspection and critique. Since this is your first design to be printed, there should be very little feedback around the functionality of the design and performance. Once you have gotten a green light, it is time to manufacture the physical prototype.

After the physical prototype has been manufactured, begin to run tests based on the critical parameters for your design. Evaluate the product for functionality, strength, form, design, and performance in real life or simulated environments. The testing is the last stage before you return to your digital file. The results obtained here will be the blueprint that guides you in effecting all the required changes in your design and bringing it one step closer to the perfect product.
