AML3D to WAM 3D print colossal eight-tonne pressure vessel for ExxonMobil

Australian large-format 3D printer manufacturer AML3D has been contracted to build a massive eight-tonne pressure vessel by oil and gas multinational ExxonMobil.

Having received a $190,000 order from ExxonMobil, AML3D will now utilize its Wire Arc Manufacturing (WAM) facilities to produce the container, in a way that reduces its lead time from 12 months to just 12 weeks. As well as helping its client meet a tight delivery deadline of September 2022, AML3D says the project demonstrates 3D printing’s potential in an oil and gas sector where it’s increasingly gaining traction.

“Signing this deal with ExxonMobil is a further demonstration of delivery against our multi-phase growth strategy,” said Andrew Sales, MD of AML3D. “We have a major focus on building our capability and presence in the global oil and gas sector as an immediate value driver for the business and this contract absolutely aligns with that objective.”

Alstom and Replique aim for rolling stock series production with 3D printing technology

Alstom, a France-based rolling stock manufacturer, has begun using Replique’s on-demand 3D printing services for its industrial series production applications.

The firm has chosen to digitize a portion of its supply chain, citing manufacturing flexibility, shorter lead times, and lower costs as primary factors for the decision. With help from Replique, Alstom can produce small batches of metal components for its trains in a decentralized manner, enabling the firm to better address the local needs of clients worldwide.

Leveraging the recent partnership, Alstom has already received and installed its first set of visible 3D printed train parts: door stoppers made of stainless steel.

A 3D printed bridge gives new shape to large-scale manufacturing

In October of 2017, the first 3D printed bridge bore a group of hard-hat-wearing city officials on bicycles as they wobbled across a canal in the city of Gemert in the Netherlands.

Officials and locals celebrated the opening of the 26-foot (8 meters) bridge that connects two roads over a small water-filled canal, said Phys.org. This structure represents a milestone for 3D printing of large-scale objects.

Printing the bridge’s 800 layers took about three months. The designers say the reinforced, pre-stressed concrete can handle loads equivalent to the weight of 40 trucks. In Amsterdam, Dutch startup MX3D is printing components for a stainless steel bridge to span a canal, according to Phys.org.
