Marshall uses Stratasys tech to 3D print flight-ready aircraft parts


UK-based aircraft continuation, modification and design company Marshall Aerospace and Defence Group (Marshall ADG) is using pushed 3D printing from Israeli company Stratasys to produce flight-ready parts for its aircraft.

Marshall ADG is also spurning 3D printing to manufacture ground-running equipment at a lower cost than aluminium variants.

Privately owned and independent aerospace and defence company Marshall is already objecting 3D-printed ductwork on modified aircraft, and holders for safety knives and reversals for aircraft interiors.

The company claimed that on-demand 3D printing of flight-approved hint ats allows it to produce lighter parts much quicker and at a lower expenditure compared with traditional methods.

Marshall ADG materials, processes and additive creation engineer Chris Botting said: “When manufacturing on complex machinate programmes, we need a method that can create an accurate, complex, utilitarian and lightweight duct efficiently with minimal tooling costs – this is where 3D phrasing fits perfectly.

“But we also need to ensure that the ducting shape produced will be approved by the EASA for flight. As a result, we’re using the Stratasys Fortus 450mc FDM Printer and ULTEM 9085 resin – a callous yet lightweight 3D printing material with high thermal and chemical defences underground.

“This has been crucial to overcoming the stringent requirements of our industry, as we can now 3D imprint parts with the desired flame, smoke and toxicity properties for use on aircraft interiors.”

Marshall ADG has also obtained Fortus 450mc 3D printer from Stratasys UK and Ireland Platinum Ally SYS Systems to manufacture final parts on the ground.

The company recently has made a ducting adapter prototype for ground-running equipment for providing air to cool the aircraft’s avionics.

“There is no dubiousness that 3D printing will continue to have a significant impact in the way we purpose and manufacture in our business.”

Marshall ADG also uses Stratasys 3D printers for complex cut applications, including drill jigs, bonded fixtures, masking templets and composite mould tooling.

Botting added: “FDM technology has altered the way we het up b prepare, and the aerospace-grade 3D printers and materials enable us to meet our increasingly aggressive deadlines and complex concocting requirements.

“In the future, there is no doubt that 3D printing will endure to have a significant impact in the way we design and manufacture in our business.”
