| $500K-$2M capital investment for equipment | Zero capital investment |
| 6-12 months facility setup | Immediate access to production capacity |
| Fixed capacity, difficult to scale | Elastic capacity matching demand |
| High overhead regardless of production | Pay only for what you use |
| Specialized staffing requirements | Expert engineers included |
| Equipment obsolescence risk | Always current technology |
Why Three Technologies Matter
Different applications require different solutions. Your On-Demand Factory for SLA, SLS, and SLM Metal 3D Printing provides comprehensive capabilities:
SLA (Stereolithography) for precision and surface quality SLS (Selective Laser Sintering) for functional durability
SLM (Selective Laser Melting) for metal performance
This trinity of technologies ensures the right process for every application.
Understanding SLA: Precision and Detail Excellence
Stereolithography remains the gold standard for applications requiring fine detail and smooth surface finishes.
How SLA Technology Works
The SLA process involves these precise steps:
- Resin vat preparation: Photopolymer resin fills a shallow tank
- Laser scanning: A UV laser traces each layer’s cross-section
- Layer curing: Exposed resin solidifies instantly upon laser contact
- Platform movement: The build platform descends by one layer thickness (typically 25-100 microns)
- Recoating: A blade spreads fresh resin for the next layer
- Repetition: Steps 2-5 repeat until the part is complete
- Post-processing: Parts are washed, supports removed, and cured under UV
SLA Applications and Best Use Cases
Perfect for:
- Visual prototypes: Marketing models, trade show displays
- Microfluidics: Channels as small as 0.1mm diameter
- Dental and medical: Surgical guides, dental models
- Jewelry casting: Investment casting patterns with fine detail
- Flow analysis: Clear models for fluid dynamics visualization
SLA Material Portfolio
| Material | Key Properties | Applications |
|---|---|---|
| Standard Clear | Optical clarity, smooth finish | Flow visualization, light pipes |
| Tough Resin | Impact resistant, ABS-like | Functional enclosures, snap fits |
| High-Temp | 289°C heat deflection | Mold tooling, thermal testing |
| Castable | Clean burnout, fine detail | Jewelry, dental restorations |
| Biocompatible | USP Class VI, autoclavable | Surgical guides, medical devices |
| Flexible | Shore 80A-90A, rubber-like | Seals, gaskets, wearables |
Understanding SLS: Functional Strength and Durability
Selective Laser Sintering produces robust, functional parts ideal for mechanical applications and end-use production.
The SLS Process Explained
Step-by-step manufacturing:
- Powder bed preparation: Polymer powder (typically PA12 nylon) is heated just below melting point
- Laser sintering: A high-powered CO2 laser selectively fuses powder particles
- Layer fusion: Each new layer bonds with the previous, creating solid parts
- Self-supporting builds: Unsintered powder surrounds and supports the part
- Cooling period: The build chamber cools gradually to prevent warping
- Part extraction: Parts are removed from the powder cake
- Cleaning: Excess powder is removed via blasting and filtration
Why SLS Excels for Functional Parts
Key advantages:
- Isotropic strength: Material properties are consistent in all directions
- No support structures: Complex geometries build without additional supports
- Living hinges: Flexible features that can flex thousands of cycles
- Snap fits: Integrated assembly features with proper tolerances
- Batch efficiency: Multiple parts nest efficiently in the build volume

Understanding SLM: Metal Manufacturing Without Limits
Selective Laser Melting brings metal additive manufacturing to Your On-Demand Factory for SLA, SLS, and SLM Metal 3D Printing, enabling complex geometries impossible with traditional machining.
The SLM Metal Printing Process
Precision manufacturing sequence:
- Build plate preparation: Metal substrate is leveled and secured
- Powder dispensing: A thin layer (20-50 microns) of metal powder is spread
- Inert atmosphere: Argon or nitrogen purges oxygen from the chamber
- Laser melting: Fiber laser fully melts powder particles at precise locations
- Solidification: Molten metal solidifies instantly, creating dense material
- Layer buildup: Process repeats, with each layer fusing to the previous
- Heat treatment: Post-build stress relief and heat treatment
- Support removal: Machining away supports and detaching from build plate
- Finishing: Surface treatment and final inspection
