Beyond prototypes: 3D printing

3D printing has been a buzzword for many years, with exciting developments cropping up in many sectors, including medicine, where the first 3D printed heart recently made headlines, construction and automotive.

But what about the packaging industry? Elisabeth Skoda examines three very different 3D print applications in the industry – ranging from reverse engineering more durable parts for packaging machines, creating more sustainable coffee cups and enabling creative uses for packaging waste.

Reverse engineering against wear and tear

A sweets producer in the Netherlands uses additive manufacturing to replace fast-wearing machine parts more efficiently. The Chocolate Factory in Rotterdam faced the problem that high-speed applications in the chocolate packaging process resulted in high wear on individual parts and was looking for solutions to make part replacement easier and faster. How could 3D printing reduce machine damage, downtime and material costs?

Production-scale use of 3D printing at ‘tipping point’

A study about additive manufacturing released in mid-March by Essentium Inc. and Dimensional Research concludes that confidence in and deployment of industrial-scale 3D printing (3DP) is at a tipping point among users.

The study, “3D Printing at Scale,” reveals that 22 percent now use 3D printing for full-scale production runs of parts and 36 percent expect to in the future. Sixty-one percent use 3DP for prototyping work; 58 percent expect to do so in the future.

Besides reducing manufacturing costs, the transformational impact on manufacturing from industrial-scale 3DP is expected to be far-reaching, according to the survey findings. Forty-three percent of respondents believe it will make the mass-customization of products possible, 39 percent expect to gain a competitive advantage from a dramatic acceleration in the cycle of design to proof of concept to mass production, and 38 percent expect to bring the manufacturing supply chain closer to the customer as outsourcing production of parts to other geographies for economic purposes becomes redundant.

How to scale up to serial 3D printing production

Efficient serial production – true additive manufacturing – is the real game changer. Four case studies demonstrate how scaling up to serial 3D printing production represents a huge opportunity for manufacturers.

Labman Automation use 3DP parts in their custom laboratory automation and robotics equipment.Yorkshire-based Labman Automation creates custom laboratory automation and robotics equipment; this fast-growing small business has been working with Materialise for three years to produce bespoke parts for its machines.

“Our job is to be creative and the design freedom of 3D printing gives us free rein to come up with interesting and novel solutions for our customers,” says Rob Hodgson, Inventor at Labman Automation.

3-D printing: A tool for production

Worker using the Ultimaker 3.Interest from manufacturers and big chemical companies shows that 3-D printing isn’t just for hobbyists

t its Autoeuropa factory in Portugal, where it assembles 100,000 cars a year, Volkswagen has deployed a fleet of desktop three-dimensional printers made by the Dutch firm Ultimaker. Last year, the machines printed more than 1,000 plastic tools and fixtures Volkswagen needed around the plant. One example is a plastic jig that workers place over the wheel so they can tighten lug nuts without scratching the rim.

Previously, Volkswagen had to rely on third parties, such as machine shops, to fabricate such parts. Between sending the design out, waiting for delivery, and testing, the process for making a simple object like a window alignment gauge could take 60 days. With 3-D printing, workers have the parts in their hands in less than a week.

Accuracy vs. Resolution in 3D Printing: Understanding the difference

A lot of words are commonly thrown around when talking about 3D printers and their capabilities. Two of those words are accuracy and resolution, which are often treated as interchangeable – but they’re really not. There’s a difference, and it’s important to understand what that difference is if you’re going to find the right 3D printer for your specific application – especially regarding applications like dental 3D printing, where precision is of the utmost importance.

EnvisionTEC recently published a white paper entitled “Understanding 3D Printer Accuracy: Cutting Through the Smoke and Mirrors,” which will be circulated at the ADA 2017 show in Atlanta later this month. You can also read the full paper here.

3D printing adds another dimension as tool for production, not just prototypes

Advancing technology and lower costs have some Seattle-area companies looking to 3D printing for faster, cheaper product tweaks and for full-fledged manufacturing as well.

Prevolve employees Krista Nelson, left, and Stephanie Brossmann demonstrate how a foot scan is taken to gather data to feed into a 3D printer at Prevolve, a company that makes running/walking shoes.  (Ken Lambert/The Seattle Times)Oliver Brossman struggled for years to find soccer shoes that fit properly and let him run after painful knee injuries. After a futile search, he decided to create his own.

In hopes of making a better shoe, he turned to 3D printing to create custom-fit running shoes. He founded Prevolve, despite no coding knowledge or background in 3D printing.

Three years of prototyping and testing later, the company just launched its first product, BioRunners, a high-end personalized running shoe designed to be better for your body.
