Packaging redesigns are a serious undertaking. On the marketing side, changes are visual and emotional; on the manufacturing side, changes cost money.
Before making the investment to overhaul its glass bottle tooling systems, the maker of James Boag’s Premium Lager needed to know an update to its bottle would not be change for change’s sake. It needed to be sure the new bottle would look good and be well received by customers. Ideally, this confidence would come before spending major time and capital on the project.
As the supplier of Boag’s bottles, Orora had skin in the game to validate the design quickly and accurately. Orora’s Innovation & Design team put wheels into motion by contacting 3D Systems On Demand Manufacturing, a long-time partner, to develop a state-of-the-art 3D printed prototype. Keeping Boag’s existing supply chain processes top of mind, a new-look bottle was designed to comply with the manufacturing infrastructure already in place to help avoid expensive and time-consuming changes.
To get Boag’s buy-in on the new design, a credible appearance model was needed for evaluation. To be convincing, the 3D printed models needed to have the same clarity and hue as glass as well as the same in-hand heft. 3D Systems’ experts accounted for weight disparities by adjusting the interior wall thickness of the design file based on the density of the selected stereolithography (SLA) resin, and then got to work on colour-matching to achieve the iconic green of the classic Boag bottle.
Using 3D Systems’ leading SLA 3D printing technology and VisiJet SL Clear resin, 3D Systems’ On Demand Manufacturing experts printed four SLA prototypes.
“Successful lab testing of 3D Systems’ clear materials verify they are the best solution for transparent 3D prints,” said Dr. Don Titterington, Vice-President of Materials R&D, 3D Systems. “Used in a variety of demanding applications, clear materials deliver high-performing, cost-effective choices for functional, transparent prototypes.”
Once printed, the bottles were put through an in-house finishing protocol to bring them to final product quality. This included wet and dry sanding, applying a surface tint, and a final clear coat to deliver a glass-like sheen. With just a few simple steps, clear SLA prints can be transformed with incredible results.
According to Tracy Beard, General Manager for 3D Systems’ facility in Lawrenceburg, Tennessee, thousands of clear parts are produced at the facility each week: “The materials are versatile enough to be quickly finished and tinted for perfect prototypes.”
The appearance models were ready within a week, allowing Orora and Boag to quickly transition the new design to customer trials and gauge the public’s reaction. They filled the 3D printed bottles with liquid, outfitted them with a label and cap, and put them in a shop for monitoring. Feedback from these in-store trials indicated that the new design was a hit, clearing the new design for production.
“The new James Boag’s Lager bottle has set a standard within Orora for the way packaging design and 3D prototyping can come together seamlessly with short notice,” said a spokesperson for Orora’s Innovation & Design team. “It’s the sort of technology innovation that’s giving us a critical edge when it comes to developing best-practice bottling design and manufacturing solutions for our customers.”
