Spare Parts

Revolutionize your approach to producing and managing spare parts

Are spare parts taking up too much space or becoming too difficult to source? With 3D printing, you can order and receive the replacement parts you need the moment you need them, reducing storage costs, over-production, and the risk of obsoletion. Remove your dependence on physical stock and the constraints of traditional manufacturing to design and source parts that are truly fit for purpose. 

A series of 3D-printed repair kits with EASA 21.J quality labels. The kit contains small white plastic parts made of flame-retardant polyamide, designed by Expleo. These parts are used to replace commonly broken latches on Boeing 737 dado panels.

Why choose 3D printing? 

Free up your capital 

Holding an inventory of spare parts ties up significant working capital that could be better invested elsewhere. With 3D printing, you can directly impact your bottom line by freeing up this capital with a digital inventory and on-demand production. 

Shorten your lead times 

Print the parts you need quickly and easily, limiting downtime — no more long waits for those urgent missing components. By taking production into your own hands, you can reduce your dependence on suppliers and ensure you’re not caught out. 

Avoid costly pitfalls 

With 3D printing, you can order one-to-one replacements on demand with no set-up costs, expensive molds, or minimum order quantities to inflate the price. 

Easily improve part performance 

Thanks to digitalization and freedom of design, you can easily change or re-invent the design of your parts to meet a specific need. Create fit-for-purpose parts that reduce downtime, improve efficiency, and reduce costs. 

3D-printed spare parts success stories

Discover how additive manufacturing helped these companies optimize the production of spare parts. 

Two small metal parts are placed next to each other. On the left is a new, 3D-printed stainless steel bracket with no visible assembly seams. On the right is an old, rusted bracket with visible seams showing it has been assembled from multiple parts. These brackets are used by Philips Lighting in the manufacturing of lightbulbs.
A bracket used in Signify's (formerly known as Philips Lighting) production process was very prone to breakage, with at least one failure per week. Materialise co-engineered and printed a new single structure bracket, reducing time-consuming part assembly and completely removing weld line pressure points.
Four 3D-printed spare parts made of flame-retardant polyamide are shown: one is black and three are white. All four parts are commonly seen in aircraft cabin interiors. These parts are manufactured for 328 Support Services.
328 Support Services handles the maintenance, modification, and refurbishment of around 180 operational Do328 aircraft around the world. In preparation to re-launch serial production of this airliner, 328 worked with Materialise to make plastic spare parts lighter, cheaper, and faster to produce.
A series of 3D-printed repair kits, small white plastic parts made of flame-retardant polyamide, designed by Expleo. These parts are used to replace commonly broken latches on Boeing 737 dado panels.
Working together, Materialise and Expleo developed an EASA-compliant 3D-printed repair kit used to fix defective dado panels on Boeing B737s, saving the company from spending time and money on unnecessary replacements.
