Plastic 3D Printing

When did the Aerospace & Aviation industry start using 3D printing?

The aerospace industry has led industrial transformation with 3D printing since its early adoption in 1989. Today, additive manufacturing (AM) represents the next stage of this evolution. The global aerospace AM market was valued at approximately $4.8–$5.9 billion in 2023–2024, with projections exceeding $15–$17 billion by 2030–2033.

Globally, aerospace applications have progressed beyond prototyping into composite tooling, jigs, fixtures, and certified end-use components. Industry studies published by Stratasys highlight manufacturers producing flight-ready air ducts, instrumentation housings, wing structures, and Unmanned Aerial System (UAS) components using industrial additive platforms. This demonstrates that additive manufacturing has transitioned from experimental use to operational deployment in their production flow.

In Singapore, the focus will be on adopting advanced manufacturing techniques, exploring new materials like composites, and leveraging technologies and predictive maintenance. As a regional aerospace hub anchored by the Civil Aviation Authority of Singapore and strengthened by advanced aerospace manufacturing clusters and industry associations, both home-grown enterprises and multinational partners face operational demands to:

Shorten turnaround time for MRO operations
Localize production of complex aircraft parts and components
Strengthen supply chain resilience amid global disruptions
Improve manufacturing flexibility for specialize aerospace components
Maintain strict regulatory and safety compliance
Accelerate smart mobility solutions

AM directly supports these strategic priorities by enabling faster production cycles, decentralized manufacturing capability, digitalization and weight-optimized component design aligned with regulatory requirements.

What are the industry challenges?

Aerospace and aviation procedure requires strict standards in precision, weight, certifications and speed including:

Tight tolerances
Flame, smoke and toxicity compliance
Structural integrity under thermal and mechanical stress
Traceability and documentation
Production scaling and low-volume customization

Conventional or traditional methods (such as CNC, casting, injection molding) usually fall short in these areas:

Long tooling lead times (from weeks to months)
High upfront mold and tooling investment
Material waste
Limited design freedom
Escalating costs for engineering changes

These limitations make conventional manufacturing inefficient for low-volume aerospace components and rapid design changes. As development cycles accelerate and regulatory requirements remain stringent, manufacturers increasingly require more flexible production methods that can deliver precision, compliance, and faster turnaround.

Why Additive Manufacturing is strategically different?

AM turns complexity into advantage especially for aerospace and aviation industry. Unlike subtractive methods, intricate designs, internal channels, lattices, weight-optimized geometries, and integrated assemblies are feasible without secondary tooling. Here's the 6 proven additive manufacturing advantages :

1. Scaling impacts across applications

Rapid part replacement for MRO providers
Customized interiors, manufacturing aids and fixtures for OEMs
Iterative structural designs for UAS
Optimized composite tooling
Weight reduction parts without compromising strength

2. Supports applications from supplementary tool to core capability

a) Composite Tooling

Structural repair tooling
Layup molds for hand or vacuum-formed composites
Sacrificial tooling
Assembly tools and templates
Master patterns for composite part forming

b) Jigs & Fixtures

Assembly, machining and inspection
Ergonomic jigs
Ground support equipment
Wiring conduits
Trim and drill guides
Manufacturing aids

c) Production Surrogates

Installations and assembly process
Training aids for operation and service technicians
Component or sub-assembly like desired part annotation, such as “Remove before flight.”

d) End-Use / Production Parts

Instrument housing and enclosures
Seat frameworks, tray tables, interior cabin parts
Latches and brackets
Ground support parts
Bespoke fittings for customer aircrafts

e) Functional Components

Weight-optimized structural elements like wing ribs, fuselage panels
Non-critical structure areas like brackets and mounts
Insulation and air flow components like heat exchangers, ventilation, ECS tubes and ducts
Seals, protective covers, vibration dampeners, gaskets, mats, wheels, bellow

Aerospace & Aviation Applications with FDM & P3 Technology

3. Wide range of advanced materials and technologies

Today’s advanced 3D printing materials and industrial-grade systems enable companies to produce high-precision parts in repeatable production environments, ensuring consistent mechanical properties and supporting scalable manufacturing for aerospace and aviation landscape. Here's the top 2 commonly used 3D Printing production systems :

i) Fused Deposition Modeling (FDM)

FDM Technology capabilities :

Large-format structural printing
Repeatable and controlled build environments with heated chamber
Traceable output for regulated applications
Industrial-grade thermoplastic material properties

FDM thermoplastics material that are commonly adopted:

ULTEM™ 9085 resin - Used for certified interior components due to its strength-to-weight performance and flame-retardant properties (UL 94 V0 rated), supporting cabin compliance requirements.
ANTERO 840CN03 - PEKK-based with electrostatic discharge (ESD) capability and ultra-low outgassing characteristics, suited for highly customized, low-volume aerospace parts.
ANTERO 800NA - Another PEKK-based offering high chemical resistance, ultra-low outgassing, and elevated heat resistance, making it suitable for aircraft and space environments.
FDM Nylon 12CF - Combines nylon 12 base polymer with chopped carbon fiber, 35% by weight. Delivers the highest strength and stiffness-to-weight ratio that allows alternative replacement to metal components, achieving up to 75% weight saving.

ii) DLP / P3™ (Programmable Photopolymerization)

DLP / P3 Technology capabilities :

High-resolution, isotropic part performance
Consistent accuracy across production batches
Smooth surface finish with injection-molding quality suitable for interior components
Scalable low-volume end-use production

DLP / P3 photopolymer materials that are commonly adopted:

Loctite 3D IND3380 ESD - High temperature resistant resin that offers a smooth surface finish comparable to injection molding quality.
Loctite 3D 3955 FST - Certified burn-resistant with strong mechanical performance, suited for HVAC components, connectors, clamps, and functional aerospace components.
Stretch 80 - Versatile elastomer suitable for flexible, tear-resistant, rubber-like prototypes, tooling, and part fit-and-form checks.

4. Benefits of using high-performance Industrial 3D polymer materials

Flame-resistance and fire-safety standards as defined under FAA regulations
Chemical resistance
Durability, stiffness, and toughness
Thermal stability
Lightweight & High strength
Predictable mechanical performance
Strong and aesthetic for smooth surface finish
HDT & ESD properties

5. Focus on engineering-first model

Additive manufacturing isn't about machine or technology selection. It should begin with application validation and objective. An engineering-first engagement model ensures:

Structural performance assessment
Regulatory alignment
Material suitability verification
Workflow integration planning
ROI modelling for low-volume production

This approach reduces risk while accelerating meaningful adoption and scalable production. Many Singapore companies adopt a hybrid approach - starting with our service-based printing before scaling into in-house additive manufacturing with the right equipment and training.
