How SpaceX Uses 3D Printing to Build Raptor Engines — And What It Means for Malaysian Manufacturing
· technology
SpaceX reduced the Raptor engine from over 1,000 parts to fewer than 100 by using metal 3D printing. This engineering philosophy — part consolidation through additive manufacturing — is reshaping how industrial components are designed, even outside the aerospace sector.
How 3D Printing Transformed the Raptor Engine
The Raptor engine uses full-flow staged combustion. Traditionally, building such an engine required thousands of individually machined parts, each welded or bolted together. Every weld is a potential failure point under extreme pressure.
With metal 3D printing (DMLS/SLM), SpaceX consolidated hundreds of parts into single printed components. The structural engineering results are clear:
Part Consolidation in Malaysian Manufacturing
You don't need to build rocket engines to apply the principle of part consolidation. Across Malaysia, manufacturing facilities are using industrial 3D printing to simplify their tooling and end-use components:
Rapid Prototyping — Test a complex geometric design in 24–48 hours instead of waiting weeks for CNC machining or injection mold tooling.
Assembly Reduction — Combine a 5-part bolted assembly into a single printed structure. This eliminates the need for fasteners and reduces manual assembly labor.
Complex Internal Geometries — 3D printing allows for internal cooling channels and lattice structures that are physically impossible to create with a traditional drill or mill.
Real-World Example: Manufacturing Jigs
A common application in local electronics manufacturing is replacing multi-part, CNC-machined aluminum assembly jigs with single-piece, 3D printed PETG or Nylon jigs. This reduces the weight of the tool for line workers, lowers the unit cost, and allows for rapid iteration if a product line changes.

Frequently Asked Questions
Can 3D printing replace CNC machining?
For prototypes, complex geometries, and low-volume production (under 500 units), 3D printing is highly efficient. However, for high-volume production or requirements demanding extremely tight tolerances in solid metal, CNC remains the standard.
What materials are used for industrial functional parts?
Common industrial polymers include PA12 Nylon (Selective Laser Sintering), which offers excellent isotropic strength and heat resistance, as well as high-temperature FDM materials like Polycarbonate or ABS.
How much does industrial 3D printing cost?
Pricing depends strictly on part volume, bounding box size, and material selection. A functional prototype can range from RM80 for FDM to several hundred ringgit for complex SLS Nylon assemblies. Get an instant quote here.
