3D printing is the process of creating a three-dimensional object from a digital file. It works by melting or solidifying plastic or other materials and laying down successive layers to create an object.

​3D printing has become one of the most popular technologies in product design today, with more and more designers using it for everything from concept models to final prototype production. This article explores how 3D printing can work for your design workflow and some of the challenges you might face along the way.

3D printing is a process of making three-dimensional solid objects from a digital file. 3D printing or additive manufacturing (AM) technology has been around since the 1980s. Since then, the 3D printing market size has been growing while adding lots of value to many businesses. However, it only recently became affordable for home and business use.
​
3D printing is also known as Additive Manufacturing (AM) or Rapid Prototyping. An AM machine can print an object by building it up in layers based on the design you created in your CAD program, often using plastic materials that are melted and then cooled to create the final product. The 3D printer builds up each layer by adding material until the object is complete.

3D printing is a tool, not a solution. It’s important to remember that 3D printing is just one component of product design, and it will never be able to solve every problem in your workflow. 3D printing can help you:

• Create more innovative products with less risk
• Reduce time-to-market by reducing complexity during prototyping
• Optimize the manufacturing process by testing multiple prototypes at once

3D printing offers a number of benefits in product design.

• Reduce time to market: With traditional manufacturing, it can take weeks or months to get a prototype ready for testing, but with 3D printing, you can have an accurate prototype in just hours. This is especially beneficial when working with low-volume production runs that may not justify the cost associated with traditional manufacturing methods.
• Reduce the cost of development: 3D printing makes it possible for manufacturers to iterate on their designs quickly and efficiently because they don't have to wait for new tooling or molds before testing changes made to the design. This means less money spent on prototyping costs and faster turnaround times from concept through final product release (which translates into increased revenue).
• Increase quality of design: With traditional manufacturing methods, you often have very little control over the final product's appearance because parts must be molded or cast one at a time. With 3D printing technology, however - which enables designers to create finished prototypes that look exactly like the final version - there's greater flexibility in producing mirror scale models as well as functional prototypes that are more representative than what would normally be available through other fabrication processes such as casting/molding or machining.

Despite the hype, 3D printing is not a cure-all for all design problems. In fact, it is often not an appropriate solution for even the most fundamental aspects of product design.

• 3D printing is not suitable for all materials: Because it creates parts by fusing material together in layers, 3D printing is unsuitable for producing parts made of materials that melt or burn at low temperatures (like foam and rubber).
  
• Access to the technology might not be as prevalent: some consumer-level 3D printing technologies like FDM and SLA are becoming more available nowadays. However, the majority of 3D printing technologies are still relatively hard to access due to their high cost and lack of expertise to operate them. 
  

3D printing is an important technology in the product development process. Because of its speed, accuracy, and affordability, 3D printing is used at any stage of the design process. Design teams use 3D printing to validate ideas and concepts early on in the design process. This saves time and money by helping designers avoid costly rework later on in the development cycle.
​
The first stage where 3D printing can be applied is during initial prototyping. Prototypes are often printed as fast as possible so that they can be evaluated by users or other stakeholders as soon as possible. These prototypes are typically not intended for mass production but rather serve as a proof of concept or idea validation tool that helps designers decide if their current direction is heading towards something worth pursuing further. The benefit of using 3D printing technologies is that it allows you to produce multiple iterations quickly without having to wait for molds or tooling, which often takes months before being produced in metal or plastic components!

3D printing is a fast and efficient process. Designers can create, prototype, and test their products in as little as a day. This technology has been used to produce everything from intricate medical devices to custom-made shoes for astronauts on the International Space Station.

Product designers often use 3D printing to create prototypes of new products or make small changes to existing ones. Prototypes help them test the functionality of their designs before they go into full production, which saves time and money because there is no need for large-scale manufacturing until the design is finalized.
​
3D printing also allows companies to design unique items that aren't available through traditional manufacturing methods, such as injection molding or casting (the process by which metal or plastic parts are created by pouring liquid material into a mold).

3D printing is becoming more and more popular as a tool for product design. In this article, we discussed the benefits of using 3D printing in product design and outlined some of the challenges that designers face when using this technology for their projects. We also talked about how 3D printing can help designers create prototypes faster than ever before!

Now that you have an idea of the great value 3D printing can bring you, you should consider diving deeper into exploring what the technology is all about and exploring all the values it can bring you. Luckily, we have a comprehensive program made just for that: 3D Printing Opportunities and Applications. Make sure to check it out, we are looking forward to seeing you there. 

"Interesting" is the word we often hear when telling others about our innovative ideas. Unfortunately, this is mostly the last thing we hear about it before it soon dissolves in the busyness of both working and personal lives. Unless formed, shaped, and colored, ideas by themselves are defenseless and mostly worthless. How can an idea be more than just "interesting"?

One way to get past the "interesting" point and get more attention is to make your audience 'feel' the idea. This is guaranteed to give you more of their attention for a longer time. Prototyping is the best way to have your audience feel your idea.
​
In a broad sense, a prototype is whatever can give your idea a visible/tangible form and/or feeling. This can be with simple drawings, 3D printed or virtual models, videos, interface mock-up, etc. Depending on your situation, a prototype does not have to be functional or attractive. However, building a prototype does require more investment and effort than to just speak of the idea.

Here are some reasons that can partially illustrate the power of prototypes:

1. It is much more likely for people to remember a prototype than an idea.
2. Prototypes are a stronger means of communicating your ideas compared to just speaking about them.
3. Having a prototype indicates your seriousness to your audience. It shows that you have invested resources to produce that prototype.
4. Going through making a prototype forces you to refine your idea to a clearer and more precise form to deliver to your audience.
5. A prototype helps your audience imagine the impact your idea can bring.

Whether you pitch an idea to your management, investors, or teammates, having a prototype will increase your chances of taking your ideas to the next level. 

​Prototyping is becoming an essential and central practice working in design innovation. The shapes and forms of the prototypes can be very different depending on the field and purpose of the prototype. The commonality is that everything is prototype-able. For example, a user interface can be prototyped with a series of hand sketches on paper, an interactive dashboard can be prototyped with linked PowerPoints slides, a video advertisement can be prototyped with a cellphone camera, a physical product can be prototyped with 3D printing, etc. With that, it would be worth it to have rapid prototyping as a key part of your innovation processes. 

In an earlier blog post, we discussed 3D Printing and product design and how prototyping can play an important role in the field. You can also check out the 3D Printing Opportunities and Applications course that dives even deeper into 3D printing for prototyping and other fields.

The rest have mostly remained confined to industrial use. The following figure highlights the different 3D printing technologies currently available. Pictures and red rectangles are for technologies that are more available at the consumer level.  ​

AM enables you to produce unique, custom products on a small scale. For plastic-based applications, Injection Molding is the traditional counterpart for Additive Manufacturing. Both methods can produce plastic products, but the cost models are very different. The figure below highlights the difference in cost between Additive Manufacturing and Injection Molding. Additive manufacturing has a fixed cost per unit, while injection molding has a variant one that decreases the more you produce a product. This makes additive manufacturing great to create custom products on a smaller scale.  ​

AM enables you to produce products that are not possible traditional methods. This can be especially the case with metal products where the traditional counterpart is Subtractive Manufacturing. Due to its nature, AM technologies can enable the creation of internal structures that are otherwise impossible to make with traditional methods. The figure highlights a part structure that is only possible with Additive Manufacturing.  ​
