Glass Bottle Redesigned with Confidence Using Clear SLA 3D Printing

Orora earns client buy-in on new beer bottle design using color-matched 3D printed appearance models with identical heft and hue of glass

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 Australia’s 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.

3D printing a lookalike for glass

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’ On Demand Manufacturing 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 color-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 3D Systems’ Tracy Beard, general manager for On Demand Manufacturing’s facility in Lawrenceburg, TN, thousands of clear parts are produced each week in the Lawrenceburg facility alone. “The materials are versatile enough to be quickly finished and tinted for perfect prototypes,” Beard says.

Fast feedback for fast progress

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 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.”

Bonfiglioli HDO 170: The Answer to a Tight Problem

A compact but powerful Bonfiglioli HDO 170 drive selected for its durability and reliability under all conditions is helping power a Transmin low profile feeder (LPF) for a Sun Metals zinc refining operation.bonfiglioli

Bonfiglioli’s HDO 170 drive – which has been operating efficiently and productively since commissioning – was engineered and assembled in Australia to provide a space-saving solution for Sun Metals, who needed to fit the LPF with attached drive into a tight space in their existing pit. It features a 75 kW motor that produces 127,700 Nm of torque.

“The compact design was one of the major benefits of using a Bonfiglioli drive for Sun Metals’ LPF. Additionally, the service and support from the Bonfiglioli team is always prompt and professional,” says Tony Warren, lead design engineer, Transmin.

Transmin is a world-class provider of innovative engineered equipment, supplies and services to the manufacturing, mining, resources and bulk materials handling industries, with engineered equipment currently deployed in over 60 countries.

The Transmin LPF handles zinc concentrate at 400tph and is positioned beneath a large hopper, which is filled by side tipping trucks. The zinc concentrate is then fed into the process plant for refining into zinc metal.

“The reliability of Bonfiglioli’s drives is first-class. We’ve used their drives in numerous projects across Australia, including some in harsh conditions, and their durability and reliability have always been outstanding,” says Mr Warren.

“Transmin’s LPF is essentially a hybrid feeder delivering the advantages of both belt and apron feeders, plus additional unique benefits over conventional feeder technology, including the ability to change direction using a bend transition. A reliable drive is essential to power the LPF and provide consistent performance for our customers like Sun Metals,” he says.

Mr Warren adds that apart from the quality that is engineered into the heavy-duty drive, it’s the service from Bonfiglioli that sets it apart. “Their team worked with us from day one to provide a custom-tailored solution for Sun Metals, and they were there throughout the entire process. They have also been helpful and available for any after-sales service we have needed.”

Selfa Arctic: The World’s First Hybrid Fishing Boat

Electric now meets diesel on the high seas.

Selfa Arctic, the world’s first hybrid fishing boat began operations off the coast of Norway. Fuel savings are close to 70%.selfa arctic

Diesel is the single largest cost for the global fishing industry, as well as its main source of greenhouse gas emissions. Catching a metric ton of North American salmon consumes 886 litres of diesel, according to a study by Australian researchers.

Other types of fish require even more fuel, driving up costs for fishermen and consumers alike. And with the advent of carbon pricing, diesel will not only be expensive to buy, but also to burn.

Since one litre of diesel produces more than 2.5 kg of CO2, the combined carbon emissions from global fishing operations are huge.


Selfa Arctic AS (Norway) built ‘Karoline’ for fisherman Bent Gabrielsen from Karlsøy in the northern part of Norway, in collaboration with researchers at SINTEF and Siemens who was the main supplier for the onboard electrical systems. The small, one-of-a-kind vessel is equipped with two battery packs that have a total capacity of 195 kWh, as well as a diesel engine for off-grid charging if necessary, which together power the boat for a full day of fishing in the Norwegian Sea.

Running on diesel to and from the fishing grounds, Karoline switches to electricity for fishing, loading and unloading. It runs electric-only for almost three hours every day, and the batteries are fully recharged in port overnight. The boat’s electrical supply has proven faultless after three years of operation.

Karoline is a pilot project, and the vessel’s performance is being closely monitored by SINTEF researchers. The data collected are being used to design new hybrid boats with an engine featuring an optimal mix of power sources for different tasks. The researchers hope to build even more energy-efficient boats in the future.


Fuel savings and emission cuts are the two obvious benefits of a hybrid fishing boat. But hybrid vessels also reduce noise and exhaust from diesel engines, improving working conditions for fishermen.

Additionally, during the period in which the engine runs on electricity, sounds from pumps and other machinery become more audible, thereby improving onboard maintenance and safety.

Karoline is operating successfully in the harsh climate north of the Arctic Circle, so the vessel can be expected to function smoothly in any waters.


Small, motorised fishing boats number more than 2.5 million globally, according to the UN Food and Agriculture Organisation. Small boats particularly dominate in inland fisheries, where they account for as much as 91% of all motorised vessels. With increased electrification across all sectors of society, the market for hybrid fishing boats is potentially massive.

Selfa is currently working on new and upgraded versions of its hybrid fishing boat. Technology and experience from the Karoline project has also been utilised for developing low and zero emission products for the fish farming industry.

A & G Price: New Zealand’s Engineering Phoenix Rises

It was a tragic day for the New Zealand engineering landscape when A &G Price, one of New Zealand’s largest and oldest engineering companies, was put into voluntary liquidation in July 2017.

That could have signalled the end of some 149 years of trading, and for most it would have.

But Gareth Hoole, a liquidator at Ecovis KGA, armed himself with his vision of the operation’s potential. He had a plan that would see the entire plant reopening, and not only to fulfil partially completed orders but to continue to trade by taking on new orders. This, Hoole reasoned, would mean the company could be sold as a going concern.

However, eight months and a dozen or so interested parties later, the sheer scale shadowed such potential – ever so apparent that A&G Price was a much bigger entity than most were willing to take on.

Enter Chris and Jackie Reeve to change the playing field.

The couple could see the potential in the company and its associated benefit to the entire Thames community. They stepped up and purchased it and on April 3 – in its 150th year – A & G Price Ltd officially reopened with a team of 34 loyal staff.

None of the equipment had been removed during the liquidation so the company was immediately in full capability to service the engineering needs of medium and heavy industry.

A & G Price is the only one-stop heavy engineering shop in New Zealand – and arguably Australia – with a fully-integrated engineering works that includes design and project management, ferrous and nonferrous foundry with a melt capacity to 10 tonne, computer-controlled high temperature heat treatment, full machine, fabrication, fitting, NDT, blasting and paint shops all on the one site.

Utilising a library of reference material that would be the envy of most consultancies, and backed by the expertise captured in a work archive of more than 100,000 technical drawings spanning 150 years, A & G Price Ltd has the ability to bring customers concepts to reality, or improve on existing machinery to maximise production.

The foundry has the ability to produce castings from as small as 300 grams in all grades of cast iron, SG iron and steel, most common grades of stainless steel, brass and bronze. All of these grades can be welded in the 104-metre long fabrication shop, with 20-tonne lifting capacity and full complement of presses and plate processing machinery, welding technicians ticketed to ASME IV and a wealth of knowledge spanning three centuries for fabricating exotic materials, weld overlaying worn-out equipment or welding dissimilar grades of material. In short, A & G Price has the ability to undertake all welding requirements to the highest standards.

These components can then be machined in its large machine shop capable of manufacturing complex components a few mm’s in size to CNC milling machines up to 10-metres long and turning capacity to 6.15-metres diameter x 40 tonne. With highly-skilled staff experienced in handling and machining large heavy items or smaller mass-produced components, customers can be assured all their requirements will be delivered in spec and fit for purpose.

The entire works is certified to operate under ISO9001 2015. Its QA department includes fully-qualified NDT technicians for MPI, dye penetrant and ultrasonic inspection, and can offer full traceability and compliance to any standard and acceptance level. This is common-place for the company’s military, rail and hydro-electric customers but is becoming more common-place as other industries realise the cost of down-time and the benefits of receiving quality components.

A Welding Solution: Time to Move to Improve Staff’s Air Quality

Family-owned Melrose Kiwi Concept Chairs has supplied mobility products for more than 25 years, and is a major brand for wheelchairs in New Zealand and Australia.

The company’s Christchurch-based manufacturing plant employs six full time welders, with other production staff, needing effective fume extraction.melrose kiwi concept chairs

As the company has grown, Melrose decided to centralise its extraction system but wanted the flexibility for each extraction point to cover two bays. NZ Duct+Flex visited the site to see how best to achieve effective fume extraction to fit with the workshop’s activity.

NZ Duct+Flex’s own installation team has installed hundreds of the blue and yellow European sourced fume arms for welding fumes, and here, six 160mm/4m reach arms were used, with a mobile FumeCube, for specialist work carried out in different parts of the workshop.

“Our suppliers have been around for decades and their products have been tried and tested and enhanced over this time,” says sales manager, Geoff Ebdon. “All our fume solutions are also sourced from two major European suppliers ensuring value for money and products that actually do the job.”

Annette Melrose confirmed that all is running really well, with greatly improved air quality for staff.

The fume arm range is very robust with metal tube arms and hoods, external hinging meaning the debris being exhausted cannot cause the hinging to wear or become jammed (low maintenance).

All fume arms are in stock, available for immediate delivery from 75mm dia/1m up to 160mm dia/4m reach. Extraction arms can be driven by a fume fan, or for larger workshops with a centralised system, a JKF fan can be used.

For mobile solutions there are one or two arm fume cube units – a solid but compact mobile unit with pre-mesh filter for sparks, pull out cartridge filter and fan all in one unit.
