What are You Planning to do With Your Prototype?
Step 3: Hang on—What are You Planning to do With Your Prototype?
Business plan? Done. CAD drawing? Done. You’re probably itching to scream, “Let’s print this thing!”
Hold your horses. Before firing up the machines (as much as we love that part, too), we need to nail down exactly what your rapid prototyping goals are. Why? Because your end goal dictates your manufacturing method.
Uncover Your Prototype's True Purpose
Dust off that business plan. Even if you didn’t explicitly write out a “prototyping goal,” the clues are in there. Are you proving a concept? Wooing investors with a flashy show-and-tell? Testing the look and feel? Or maybe you’re hunting for design flaws and quality assurance?
Spoiler alert: You don’t use the same 3D printing materials for every scenario.
Comb through your plan and flag every instance that requires a physical model. You might need one version to look pretty on a display shelf and a totally different, ultra-durable version for stress testing.
Match Your Material to Your Mission
Form follows function. If you need to test aesthetics, you need to choose a prototype material selection that mimics the final product. For instance, Nylon 12 SLS (Selective Laser Sintering) 3D printing materials beautifully simulate the look and feel of injection-molded ABS (Acrylonitrile Butadiene Styrene).
Pitching to investors? Prioritize sturdy materials with fewer fragile parts so your prototype actually survives the boardroom pass-around. Testing for design improvements? Functional vs visual prototyping? You'll want to experiment with different materials to unlock specific performance enhancements.
Not All 3D Printers Are Created Equal
We all call ourselves “3D printers, ” but we don't all use the same magic.
Take our SLS process, for example. We use high-precision lasers to melt powder layers into solid, functional objects. We build with heavy-duty industrial materials—like Nylon 11 and 12 SLS 3D printing material—sometimes reinforcing them with carbon fiber or glass. On the flip side, standard desktop 3D printing usually relies on melting spools of basic plastic filament like PLA or ABS.
Every 3D printing technology brings unique strengths to the table. You just have to match those strengths to your rapid prototyping goals. Grab our Technology Material Chart to easily compare processes, materials, and crucial characteristics like:
- Durability and flexibility
- Multi-component printing capabilities
- Color options
- Surface finish (smooth vs. rough)
- UV resistance

The Fine-Tuning Process (Are We Done Yet?)
If your first 3D-printed prototype is flawless, pop the champagne—you're ready for full-scale production.
Back in reality, perfection usually takes a few tries. That first print is often just version number one. Once you hold the prototype in your hands, you'll review the design, make tweaks, and print again until it's exactly right.
Then, you decide the next step. Do you jump straight to mass production? Transition to injection molding (IM)? Keep running low-volume SLS prints while your molds are being built?
You are no longer just someone with a sketch on a napkin. You are a product developer refining a real-world invention. Keep refining, stay confident, and watch your idea evolve from a prototype into a market-ready product.
