Custom Additive Manufacturing Demonstrates Value in Elite and Adaptive Sports

Recent developments across international sporting competitions have highlighted how additive manufacturing is being used to deliver tailored, performance-critical equipment for athletes. From custom cycling aero bars and adaptive para-sport mounts to personalized bow grips and drivetrain components, low-volume additive production offers rapid design iteration and custom ergonomics without the prohibitive tooling costs of traditional manufacturing.

Solving the Low-Volume Customization Problem

In high-performance and adaptive sports, equipment must often fit a single athlete’s specific anatomy or mechanical preferences. Traditional production methods like CNC machining or injection moulding struggle with one-off parts due to high setup costs and specialized tooling requirements. Additive manufacturing sidesteps these limitations, allowing designers to iterate rapidly and produce final production parts on the same machine architecture used during prototyping.

For example, UK-based service provider 76 Additive developed custom computer mounts and ergonomic grips for para-triathletes, alongside aerodynamic lattice structures for cycling. Similar approaches have been applied using Markforged continuous carbon fibre printing to produce lightweight handbike crankarms and custom gloves, as well as Hyundai’s ongoing production of tailored bow grips for Olympic archers.

Combining Multi-Material Technologies for Functional Gear

Beyond single-material components, functional sports equipment increasingly relies on hybrid additive processes. Certain training aids pair rigid structural shells with flexible elastomeric lattice structures. Rigid components are often produced using polyamides like nylon via selective laser sintering or Multi Jet Fusion, while flexible impact or comfort elements utilise elastomeric resins or TPU materials.

This multi-process approach allows engineers to tune stiffness, weight, and ergonomics independently within a single functional assembly, solving complex mechanical requirements without requiring extra mechanical fasteners or complex multi-part assemblies.

What This Means for South African Makers

While high-end athletic setups often utilise industrial SLS or continuous fibre systems, the underlying design principles apply directly to local desktop printing environments. South African engineers, sports enthusiasts, and small-scale fabricators can leverage accessible FDM and resin desktop printers to produce bespoke sports accessories, custom grips, and adaptive equipment.

With engineering materials such as carbon-fibre reinforced PETG, polycarbonate, TPU, and high-strength nylons readily available for desktop FDM machines, local makers can produce functional, high-strength parts tailored to individual user needs. This opens opportunities for local bicycle fitters, custom equipment makers, and prosthetic modifiers to prototype and produce functional components on demand.

DC3D’s Take

The use of 3D printing in elite sports demonstrates that additive manufacturing has matured beyond rapid prototyping into true low-volume functional production. For small workshops and local print farms, custom ergonomic equipment is one of the most practical applications of 3D printing technology.

Success in these applications relies heavily on choosing the correct material and designing for the specific mechanical load. High-stress parts require proper layer adhesion, orientation planning, and appropriate filament selection—such as fibre-filled filaments for rigidity or flexible elastomers for vibration dampening. By focusing on practical design iteration and material properties, makers can deliver commercial-grade custom solutions without industrial budgets.
