Direct glass 3D printing may still be a mirage but the Stölzle Glass Group, a large European company specializing in the production of high end glass bottles and containers for the Perfumery & Cosmetics, Prestige Spirits as well as Healthcare & Consumer markets, has just purchased two 3D printers that will allow it to make its bottles better and faster.
The Group has been carefully researching the many different systems and options available and finally, in line with trends that have seen both FDM and Jetting 3D printers become available at more accessible prices, has decided to purchase both types of systems to cater to its different needs.
The exact models and brands of the chosen 3D printers were not disclosed. Judging by the technical specifications that were made public, the full investment for both systems was likely a relatively small sum for a group that has five production sites across Europe. Yet benefits may be very large.
Stölzle is now able to increase efficiency by solving any issue that may arise with customers requests, as well as give form to new and more complex ideas by producing 3D models at a low cost in hours instead of weeks. According to the company, many of its customers already appreciate the benefits of the new service
The FDM system, with a 280 mm x 368 mm cylindrical build platform, was purchased by its Stölzle Flaconnage division, to make objects using ABS, PLA and T-glass filament. The high definition system was purchased by the Austrian headquarters. It can create objects with a maximum size of 200 mm in diameter and 185mm in height that do not require further processing like polishing or removal of supporting material.
The sample bottles 3D printed by stereolithography are made of UV cured translucent acrylate resin, with a 32 micron layer resolutions, around a wax support structure that can be melted away. This allows the sample bottle to be filled with material and even used for testing closures supplied by the customer.
Although Stölzle’ use is not yet an application of 3D printing in the production of final consumer goods, it is yet another example of companies working with consumer goods adopting the technology in their development process. The benefits will probably soon justify further investment by the Group to widen the range of machines available. Soon they might begin using additive manufacturing for final products as well.
