Design Better, Faster: Tip of the Month from Our Experts
In the fast-moving world of product design, staying competitive means constantly evolving your processes and tools. To help you stay ahead, we’re sharing our top design tips, with practical ways to improve design workflow, refining your prototyping process, enhancing 3D modeling, or integrating better communication with manufacturers, these insights will help you understanding how we design better and faster.
1. Speed Up Prototyping with 3D Printing
Prototyping is a key step in product development, allowing designers to test concepts before moving to production. In the past, creating prototypes was often a lengthy and expensive process, but modern techniques such as 3D printing have dramatically accelerated this phase.

Why Use 3D Printing for Prototyping?
3D printing, or additive manufacturing, builds objects layer by layer, enabling the creation of highly accurate prototypes in a short amount of time. Materials used in 3D printing range from plastics to metal, meaning you can create functional prototypes that closely resemble the final product.
Key Benefits of 3D Printing in Prototyping:
- Faster Iterations: With 3D printing, you can create a prototype in a matter of hours, allowing for quick testing and iterative improvements. This is especially helpful when exploring various design options in a limited time frame.
- Cost Efficiency: Traditional methods like CNC machining can be expensive, especially for complex designs. 3D printing eliminates many of those costs, making it an affordable option for rapid prototyping.
- Customization: If your design requires personalization or adjustments between iterations, 3D printing allows for easy customization. This is particularly useful in industries like healthcare, where products often need to be tailored to individual needs.
Pro Tip: Test Functionality with High-Fidelity Prototypes
While low-fidelity prototypes are great for visualizing shapes and forms, consider using higher-quality materials for testing functionality, especially for parts that require mechanical or structural validation. Materials like resin or even certain types of metal can mimic the real-world performance of the final product, enabling you to test fit, form, and function.
2. Parametric Modeling for Quick Adjustments
Designers often spend too much time manually adjusting dimensions when modifying designs. Parametric modeling is a powerful approach to help alleviate this issue.
What is Parametric Modeling?
Parametric modeling involves creating a 3D model based on a set of rules and constraints, known as parameters. For example, when designing a component, you can define its length, width, and height as adjustable variables. If you change one parameter, the model updates automatically according to the predefined rules. This approach is widely used in software like SolidWorks, Autodesk Fusion 360, and PTC Creo.

Benefits of Parametric Modeling:
- Efficient Design Changes: Instead of manually updating each component, parametric models adjust all related elements automatically when you modify a parameter. This is a huge time-saver when dealing with complex assemblies.
- Design Reusability: Parametric models allow you to easily reuse parts of your design for future projects. By adjusting a few key parameters, you can quickly adapt a design to meet new requirements.
- Consistency Across the Design: Parameters ensure that changes made to one part of the model are reflected across the entire design, maintaining overall consistency.
Pro Tip: Plan Your Parameters Carefully
Before starting the design, think about which dimensions are likely to change in the future. Set up your model in a way that allows flexibility where needed. This will save you time down the road when adjustments are required, especially during late-stage design reviews.
3. Design for Manufacturing (DFM)
A product that looks great on a CAD screen may not always translate well into a manufacturable product. Design for Manufacturing (DFM) is a set of best practices aimed at ensuring that your designs can be easily and cost-effectively produced.
Why is DFM Important?
As product designs become more complex, the risk of creating something that’s difficult—or impossible—to manufacture increases. DFM helps mitigate these risks by encouraging designers to consider manufacturing processes from the outset.
Key Principles of DFM:
- Minimize Part Count: Fewer parts mean simpler assembly and lower production costs. Designers should aim to reduce the number of components while still achieving the desired functionality.
- Choose the Right Materials: Not all materials are suitable for every manufacturing process. For instance, some materials may be too brittle for injection molding but work well for CNC machining. Understanding the material properties and how they behave during production is critical for a smooth manufacturing process.
- Ensure Tolerances are Manufacturable: Tight tolerances can drive up costs significantly, especially in mass production. It’s important to set tolerances that are achievable with the chosen manufacturing method.
Pro Tip: Collaborate with Manufacturers Early
Work closely with your manufacturing partners during the design phase to identify any potential issues. This early feedback can save a lot of time and effort, as they may suggest alternative methods that could simplify production or reduce costs.
4. Utilize Simulation for Performance Testing
Before committing to a final design, it’s crucial to understand how your product will perform in real-world conditions. Simulation software allows you to test your designs under various conditions without building physical prototypes.

Types of Simulations in Product Design:
- Finite Element Analysis (FEA): Helps you understand how your product will behave under stress, strain, and heat. This is essential in industries like automotive or aerospace, where product safety is paramount.
- Computational Fluid Dynamics (CFD): If your product involves airflow or fluid movement (e.g., HVAC systems, medical devices), CFD simulations allow you to test and optimize fluid dynamics before moving to physical testing.
- Thermal Simulation: Products that operate in variable temperatures, such as electronics, require thermal analysis to ensure they can dissipate heat effectively.
Pro Tip: Validate Designs Early in the Process
By running simulations early in the design process, you can catch performance issues before they become costly problems later on. Integrating simulation tools into your workflow also allows for design optimization, helping you strike a balance between performance and cost.
Conclusion
Designing better, faster products requires leveraging the latest tools and techniques, from rapid prototyping to parametric modeling. By integrating these practices into your workflow, you’ll not only save time but also improve the overall quality of your designs.
