Manufacturing guidance
3D Printing vs. Other Manufacturing Methods
Choosing the right process depends on part geometry, material, quantity, and application. Here is how 3D printing compares to CNC machining and injection molding.
Best Quantity
3D printing is ideal for 1-1,000 parts. CNC machining suits 1-10,000 parts. Injection molding becomes economical at 1,000-1,000,000+ parts with dedicated tooling.
Setup Cost
3D printing has no setup cost. CNC machining requires low fixture investment. Injection molding requires high upfront tooling cost before the first part is produced.
Lead Time
3D printing delivers parts in 3-7 days. CNC machining is similar at 3-7 days. Injection molding takes 4-8 weeks including tooling fabrication and validation.
Geometry Freedom
3D printing offers the highest geometry freedom with complex internal features, channels, and lattices. CNC is limited by tool access and setup constraints.
Material Range
3D printing offers 50+ plastics, metals, and resins. CNC offers 50+ metals and plastics. Injection molding uses production-grade thermoplastics and thermosets at scale.
When to Choose 3D Printing
Choose 3D printing for complex geometries, rapid prototyping, low volumes, no tooling budget, internal channels or lattice structures, and quick design iteration cycles.
| Factor | 3D Printing | CNC Machining | Injection Molding |
|---|---|---|---|
| Best Quantity | 1-1,000 | 1-10,000 | 1,000-1,000,000+ |
| Setup Cost | None | Low (fixtures) | High (tooling) |
| Lead Time | 3-7 days | 3-7 days | 4-8 weeks |
| Geometry Freedom | High (internal features) | Moderate (tool access) | High (after tooling) |
| Surface Finish | Moderate (post-processing) | Excellent | Excellent |
| Strength | Good (SLS/MJF close to molded) | Excellent (solid stock) | Excellent |

FAQ
3D Printing Service: Frequently Asked Questions
Answers to the questions engineers and sourcing teams usually ask before uploading drawings or CAD files.
What file formats do you accept for 3D printing?
We accept STEP (.stp, .step), STL (.stl), IGES (.igs), SolidWorks (.sldprt), and Parasolid (.x_t) files. STEP files are preferred because they preserve the most geometric accuracy. STL files are also widely used, especially for organic shapes and mesh-based designs.
How much does 3D printing cost?
3D printing costs depend on the technology, material, part size, and quantity. FDM parts start around $5-15 for small prototypes. SLS and MJF nylon parts typically range from $15-100 depending on size and complexity. Metal DMLS parts start around $50-200 for small components. Upload your CAD file for an exact price in under 60 seconds.
How long does 3D printing take?
Standard lead time is 3-7 business days from order confirmation to shipment. FDM parts can ship as fast as 1 day. SLA, SLS, and MJF parts typically take 3-5 days. Metal DMLS parts require 7-14 days due to build time and post-processing. Shipping adds 3-5 days via express courier.
What is the strongest 3D printing material?
For plastics, SLS and MJF nylon (PA 12) offer the best combination of strength, flexibility, and durability. Glass-filled nylon adds stiffness. For metals, titanium (Ti-6Al-4V) provides the highest strength-to-weight ratio, while stainless steel (17-4 PH) offers excellent hardness after heat treatment.
Can you 3D print a single part?
Yes. We have no minimum order quantity. You can order 1 prototype or 10,000 production parts. The quality, material options, and inspection process remain the same regardless of order size.
What is the difference between SLA and SLS 3D printing?
SLA (Stereolithography) uses a UV laser to cure liquid resin, producing parts with very smooth surfaces and fine detail. It is best for visual prototypes and patterns. SLS (Selective Laser Sintering) uses a laser to fuse nylon powder, producing stronger, more durable functional parts without support structures. SLS is better for functional prototypes and end-use components.
Do you offer DFM feedback on 3D printed parts?
Yes. Every quote includes free DFM (Design for Manufacturability) feedback from our engineering team. We review your CAD file and suggest design improvements that reduce cost, improve strength, or optimize your part for the selected 3D printing technology.
Can 3D printed parts be as strong as injection molded parts?
SLS and MJF nylon parts approach injection-molded strength for many applications. Metal 3D printed parts (DMLS) can match or exceed cast metal properties, especially after post-processing like HIP and heat treatment. For high-volume production where maximum strength is critical, injection molding remains the standard.
What surface finishes are available for 3D printed parts?
We offer bead blasting, sanding, polishing, dyeing, spray painting, electroplating, anodizing (for metal parts), and heat treatment. The available finishes depend on the material and technology used. SLS and MJF nylon parts can be dyed in multiple colors. Metal parts can be machined, polished, or coated.
How accurate are 3D printed parts?
Accuracy depends on the technology. SLA and PolyJet offer the finest detail at ±0.1 mm. SLS and MJF hold ±0.3% (minimum ±0.3 mm). DMLS metal parts achieve ±0.1 mm. FDM is the least precise at ±0.5% (minimum ±0.5 mm). For critical dimensions, we recommend CNC machining to achieve ±0.001″ (±0.025 mm) tolerances.
