When it comes to bringing concepts off the screen and into your hands, 3D printing stands tall against traditional methods. It’s not just faster; it’s also less expensive and allows for more complex designs.

Stratasys 3D printing surpasses traditional methods by offering:

• Superior precision and detail: High-resolution printing capable of capturing intricate details enables you to create prototypes with exact specifications and superior aesthetic quality.
• Unrivalled material versatility: With access to a wide array of materials, from standard plastics to advanced composites, you have the flexibility to realize your vision’s particular properties, from rigidity to flexibility, textured and vibrant in color.
• Faster prototyping: Double-speed printing modes and an efficient workflow allows rapid iteration and faster time-to-market.
• Larger build volume: Spacious build chambers for large prototypes or multiple parts means you can print large-scale models or batch-print smaller parts for greater efficiency.
• Excellent full-color capabilities: Over 600K color combinations and Pantone Validated palettes in PolyJet, you can create realistic prototypes that closely mimic the final product, improving design decisions and marketing presentations.
• Simplified workflow with GrabCAD software: Our Intuitive software boasts a lightning-quick learning curve and automated support generation to ease the transition from design to print, for all operator skill levels.
• Excellent thermal stability and high-temperature performance: Ensures dimensional stability and quality for prototypes intended for harsh environments or functional testing.
• New levels of customization and personalization: Capabilities like PolyJet's Smart Insert™ and Print-on-Tray and Print-on-Object offers the potential for bespoke modifications and embedded design features.

How does a 3D printer create a rapid prototype model?

3D printers create prototypes by adding material layer by layer, based on digital 3D models. This allows for intricate details and complex geometries that would be challenging or impossible with subtractive manufacturing processes.

With advanced technologies like the P3™ DLP, prototypes are not only built rapidly but also with injection molding-like quality, which is ideal for rigorous testing and end-use functionality.

What are the steps in the rapid prototyping process?

1. Digital Design and CAD Modeling
2. Preparing the 3D Printer
3. Printing the Prototype
4. Post-Processing and Finishing
5. Testing and Evaluation
6. Refinement and Optimization

Step 1: Digital Design and CAD Modeling

Every 3D-printed object starts with CAD software where you can create detailed 3D models, like Stratasys’ GrabCAD, which allows for a seamless transition from design to print, ensuring every tolerance and support structure is perfect for 3D printing.

Step 2: Preparing the 3D Printer

Selecting the appropriate 3D printing technology and material is crucial. Whether it's the robust FDM for strong, durable parts or our versatile PolyJet for models requiring fine detail and aesthetics, Stratasys printers are calibrated for excellence.

Step 3: Printing the Prototype

Next, the CAD model is processed by slicing software which translates it into a language that the printer can understand. Using Stratasys’s intuitive interfaces, importing and slicing the CAD model is simple – you can adjust print settings such as layer height and infill density for your specific needs. Then, watch as your printer does the work, turning your vision into a tangible prototype.

Step 4: Post-Processing and Finishing

Once printed, it's time for some elbow grease. Removing any supports, sanding down rough edges, and applying the finishing touches are all part of this stage, ensuring your prototype looks and feels as intended. Thankfully, if you’ve chosen a Stratasys printing solution, the time and effort involved in this stage can be cut in half. From water-soluble supports to ultra-smooth side-wall quality, the minimal amount of post-processing involved is one of our core differences.

Step 5: Testing and Evaluation

Prototypes are meant to be poked, prodded, and tested. This stage is crucial for evaluating your design's functionality and gathering valuable feedback for further iterations. From hyper-realistic PolyJet prototypes to high-performance, injection mold-quality P3 prototypes, to the durable all-rounders of FDM and Stereolithography, testing for color, form, fit and function enables greater collaboration and communication.

Step 6: Refinement and Optimization

Taking the feedback in your stride, refine and optimize your design. This may involve several rounds of tweaking and reprinting until everything is just right. The precision and repeatability of Stratasys printers mean that you can refine and optimize with confidence, achieving the desired outcome with minimal time and material waste.
