Injection Molding vs 3D Printing

Earlier last year, we discussed 3D printing. Though it has been around for quite a while, the new printing technique has only been a player in the public consciousness for about five years.

In that time, the public’s perception of what 3D printing can do has eclipsed the process’ actual capabilities. And with more recognition come more inquiries — everybody wants to explore 3D printing as an option for their next project, and are eager  to want to move on from more traditional methods, such as injection molding.

3D Printing and Injection Molding

The two processes are similar — they both primarily produce parts and components from plastic, and they are both capable of high degrees of geometric complexity. However, there are important differences as well.

One of the more appealing aspects of 3D printing is the absence of steep initial costs. Because of its need for specially tooled dies, the creation of which is an expensive process, injection molding requires considerable initial costs. Though imposing at first, these startup costs are amortized over the lifespan of the die and the production run — in large volume injection molding projects, the startup costs are amortized over more individual parts, leading to a relatively low per-part cost.

The Democratization of Manufacturing

If you follow the manufacturing space, you’ve probably heard that the industry is undergoing a significant change, accompanied by terms like “New Industrial Revolution”, “Third Industrial Revolution”, “Manufacturing 3.0” and “Maker Movement”.

We should ask, ‘What does this change actually mean for consumers?’

The new industrial revolution will have an overwhelmingly positive impact on consumer experience by allowing more customers to get what they want, when they want it and at a price they’re willing to pay. Today, no product is too quirky, offbeat, personalized or complicated to be brought to market.

Consumers can obtain these through ways like purchasing them from one of the small, agile manufacturing companies that have emerged to address customers with niche requirements. These companies have targeted customers who want a more personalized product and are willing to pay a premium for it.

Alternately, consumers can now invest in products they want by directly supporting projects in crowd-funding places like Kickstarter or Indiegogo. Crowdsourcing is also another channel for fresh ideas to become reality, with the added benefit of improving the quality of designs through cross-disciplinary collaboration and by gathering early feedback. These ideas also play nicely into the thought of Distributed Manufacturing.

The Rise of 3D Printing as the Driver of the Democratization of Manufacturing
3D-printing allows consumers to turn highly individualized concepts or designs into real-life products via a “personal manufacturing” process. As 3D-printing services and consumer devices become more affordable and ubiquitous, companies will start making digital versions of their products and parts available. Consumers will be able to download, modify and print these digital versions directly.
