3D Printing Services for
Rapid Prototyping
and Functional Parts
Accelerate product development with Rapzo's professional 3D printing services. We help engineers and product teams quickly turn CAD designs into functional prototypes and low-volume production parts — reducing development time, lowering costs, and helping you bring products to market faster.
What Is 3D Printing?
3D printing, or additive manufacturing, creates parts layer by layer directly from CAD models. Unlike traditional subtractive methods, additive manufacturing enables complex geometries, fast iterations, and short development cycles.
Applications include rapid prototyping, functional testing, and low-volume production. With no tooling required, 3D printing is ideal for early-stage design validation, custom components, and engineering samples that need to be produced quickly and cost-effectively.
3D Printing Technologies We Offer
Rapzo offers multiple additive manufacturing technologies to match your project requirements — from high-resolution appearance models to durable functional prototypes.
Stereolithography
SLA 3D Printing
SLA uses UV laser to cure liquid resin layer by layer, producing parts with exceptional surface quality and fine detail resolution. Ideal for appearance models, visual prototypes, and components requiring smooth finishes.
Selective Laser Sintering
SLS 3D Printing
SLS uses a laser to sinter powdered materials into solid parts, offering excellent mechanical properties without support structures. Best suited for functional prototypes, mechanical testing, and snap-fit components.
Fused Deposition Modeling
FDM 3D Printing
FDM extrudes thermoplastic filament layer by layer to build parts. It is the most cost-effective 3D printing method, suitable for large structural parts, early-stage concept models, and non-critical functional components.
Common 3D Printing Materials
Rapzo supports a wide range of 3D printing materials to match the mechanical, thermal, and aesthetic requirements of your project. Our team will recommend the most suitable material based on your application.
ABS
Good impact resistance and heat tolerance. Ideal for functional housings and structural prototypes.
PLA
Easy to print, good surface finish. Suitable for concept models and non-structural visual prototypes.
Nylon (PA)
High strength, flexibility, and wear resistance. Used for functional mechanical parts and snap-fit assemblies.
Resin
Ultra-high resolution and smooth surface. Best for appearance models, jewelry, and fine-detail prototypes.
TPU
Flexible, rubber-like material with excellent elasticity. Suitable for seals, gaskets, and soft-touch components.

Post-Processing & Finishing
Raw 3D printed parts often require post-processing to achieve the desired surface quality, dimensional accuracy, and functional performance. Rapzo provides comprehensive finishing services to ensure every prototype meets your engineering and aesthetic requirements.
Sanding and Surface Finishing
Manual and mechanical sanding to remove layer lines and achieve smooth surface textures suitable for appearance evaluation.
Coating and Painting
Primer coating, spray painting, and surface treatment to match specified colors, textures, and protective requirements.
CNC Machining of Critical Features
Secondary CNC machining for tight-tolerance features such as holes, threads, and mating surfaces that require precision beyond 3D printing.
Quality Inspection
Dimensional verification using precision measurement tools to confirm that finished parts meet drawing specifications before delivery.
Quality Control for Every Prototype
Every 3D printed part produced by Rapzo undergoes systematic quality verification before delivery. Our inspection process ensures that prototypes meet dimensional specifications and are ready for engineering evaluation.
Dimensional Verification
Critical dimensions are measured using calipers, CMM, and optical measurement tools to confirm compliance with CAD specifications.
Visual and Surface Inspection
Thorough visual inspection for surface defects, layer delamination, warping, and finish quality before packaging and shipment.
Engineering Approval
Parts are reviewed against engineering drawings and customer requirements before receiving final approval for delivery.
3D Printing vs CNC Machining
Understanding the differences between 3D printing and CNC machining helps you choose the right process for your project stage, budget, and performance requirements.
3D printing and CNC machining are both valuable manufacturing methods, but each excels in different scenarios. 3D printing is ideal for rapid prototyping, complex geometries, and early design validation, while CNC machining delivers superior material strength, surface finish, and dimensional accuracy for production-grade components.
Rapzo offers both capabilities, allowing customers to start with 3D printed prototypes and transition to CNC machined production parts seamlessly within a single manufacturing partner.
| Criteria | 3D Printing | CNC Machining |
|---|---|---|
| Geometric Complexity | Excellent — complex internal features | Limited by tool access |
| Lead Time | Very fast — hours to days | Moderate — days to weeks |
| Tooling Cost | None — no tooling required | Setup cost required |
| Material Strength | Moderate — material dependent | High — full material properties |
| Surface Finish | Good — post-processing needed | Excellent — precision finish |
| Dimensional Accuracy | Good — ±0.2mm typical | High — ±0.01mm achievable |
| Best For | Prototyping, design validation, low-volume | Production parts, tight tolerances, metal components |
Example 3D Printed Project
A global industrial equipment manufacturer required a complex functional prototype for a new mechanical assembly. The component featured internal channels, snap-fit interfaces, and multiple mating surfaces that would have been difficult and costly to produce using traditional machining methods.
