3D Printing Technology Explanation
Additive manufacturing (also known as 3D printing) is a method of producing complex 3-D objects by adding layers on top of each other. It provides complex geometries and custom designs without molds or tooling unlike in traditional manufacturing. It is best suited in quick prototyping, tailored components, and final use.
Our methods of meeting your particular project requirements include SLA, MJF, SLS, and SLM. With 3D printing, there is no better option than it can be flexible, and it can be fast depending on whether you require functional prototypes or low-volume production runs.
Why should we select Top Proto to 3D print?
Our 3D printing is of the highest quality and of engineering grade materials that assure longevity and accuracy. Our group customizes prototype to end-use component solutions. Our business has the capacity to produce prototyping and large scale production depending on the volume required, but our quality and delivery on time have remained constant.

Design Guide Line For 3D Printing
| 3D Printing Process | Min. Wall Thickness | Layer Height | Max. Build Size | Dimension Tolerance | Standard Lead Time |
| SLA (Stereolithography) | 0.6 MM for unsupported walls, 0.4 MM for supported walls | 25–100 μm | 1400 × 700 × 500 mm | ±0.2 MM (for >100 MM, apply 0.15%) | 4 business days |
| MJF (Multi Jet Fusion) | At least 1 MM thick; avoid overly thick walls | Around 80 μm | 284 × 354 × 544 mm | ±0.2 MM (for >100 MM, apply 0.25%) | 5 business days |
| SLS (Selective Laser Sintering) | From 0.7 MM (PA12) to 2.0 MM (carbon-filled polyamide) | 100–120 microns | 380 × 280 × 380 mm | ±0.3 MM (for >100 MM, apply 0.35%) | 6 business days |
| SLM (Selective Laser Melting) | 0.8 MM | 30–50 μm | 320 × 320 × 400 mm | ±0.1 MM (for >100 MM, apply 0.2%) | 6 business days |
Rapid Tooling
Rapid tooling let’s you go faster to go from an idea to functional parts. With our advanced CNC machining service, we create molds and tooling with precision needed to test designs, validate fit, and function and bring products to market faster. It’s perfect for prototypes, low volume runs, and early-stage development where outworking competitors is critical and precision matters most.
Production Tooling
For our production tooling, we prioritize long-term durability. With top grade materials and precision CNC machining, we make tooling that allows full-scale production without losing accuracy. If you need thousands of the same parts, and even with batch production, we deliver consistent, reliable tooling and stable production cycles.
