At Gemini Plastics, Inc., we’re proud to bring end-to-end digital manufacturing capabilities—from design to execution—into every project. In partnership with CADmore, we help turn your napkin sketches, PDFs, or legacy parts into manufacturable files with precision and speed. One powerful tool in this journey? 3D scanning. If you're missing original CAD files, working with legacy parts, or aiming to expedite complex geometry reproduction, 3D scanning is your secret weapon. Here’s when it shines.
1. When You Lack Design Documentation
No CAD model? No problem. 3D scanning captures the complete geometry of existing parts—creating digital point clouds or meshes that serve as the foundation for CAD models. It prevents you from reinventing the design and accelerates reproduction or redesign.
2. When Parts Have Complex or Organic Shapes
Traditional measurement tools struggle with curved surfaces or detailed features. 3D scanning excels at capturing free-form geometry—like molded features or intricate contours—with complete surface coverage. It's especially beneficial for organic or non-prismatic components.
3. When Accuracy and Detail Matter
Need precision? Technologies like structured-light scanners deliver high fidelity for small plastic parts—ideal for tooling, quality control, and reverse engineering. Many modern scanners can achieve sub‑millimeter accuracy, essential when reliability matters.
4. When Time Is of the Essence
Speed matters in today’s rapid development cycles. Non-contact 3D scanning is fast and covers entire surfaces without requiring probe calibration or multiple manual measurements, helping you go from prototype to production swiftly.
5. When You Want to Capture Hidden or Internal Details
Some scanning methods—like industrial CT scanning—let you see inside objects without disassembly, offering full internal and external geometry capture. This is invaluable when working with complex assemblies or concealed features.
6. When You Need Editable CAD “Design Intent”
Meshes generated from scans are great—but engineering often demands editable, parametric models. Reverse engineering transforms those scans into CAD models that encode design intent: planes, cylinders, NURBS surfaces, and features ready for modification. This becomes your blueprint for future variations.
7. When Enhancing 3D Manufacturing and Prototyping
If you're using scanned parts for 3D printing or other manufacturing, the workflow begins with a scan-to-mesh process. But to produce functional prototypes or iterate designs, your mesh must be converted into a solid CAD model. That’s reverse engineering—powered by scans.
The 3D Scanning—Reverse Engineering Workflow at a Glance
Capture: Scan the part with laser, structured-light, CT, or handheld 3D scanners.
Mesh Generation: Convert scan data into a dense mesh (e.g. STL, OBJ formats).
Post‑processing: Clean and refine the mesh—remove noise, align segments, fill gaps.
Modeling: Extract features and surfaces to reconstruct a parametric CAD model.
Integration: Use the model for manufacturing execution—whether CNC machining, molding, or printing.
Broadly, this aligns with Gemini's integrated approach: Design & Engineering + Manufacturing + ERP-driven operations.
