Stuck between expensive Injection Molding and impossible CNC designs? 🛠️
If your project is too complex for CNC and too low-volume for a $10,000 mold, SLS Nylon 3D Printing is your secret weapon. 🚀
At Unionfab, we help you bridge the gap with industrial-grade SLS parts that look, feel, and perform like production-grade plastic.
Why engineers are switching to our SLS service:
✅ Zero Tooling Costs: Save your budget for innovation, not molds (Perfect for 1–500 units).
✅ Total Design Freedom: Print complex lattices and internal channels without supports.
✅ Tough Materials: Choose from PA12, PA11, Glass-Fiber reinforced, or flexible TPU.
✅ Repeatable Quality: Professional dimensional accuracy for every single batch.
From Robotics and UAVs to Automotive prototypes—we deliver parts that are ready for the field. 🤖🚁

🛠️ Designing UAV Components? Make Sure They’re Ready for Manufacturing.

A great drone design is not only about performance —
it’s also about manufacturability, cost, and production reliability.

Before machining your next UAV component, get a professional DFM review from our engineers.

📌 We’ll help check:

✅ Material selection for your application
✅ Whether your tolerances are practical
✅ Machining challenges in your design
✅ Opportunities to reduce manufacturing costs

📎 From drone frames and brackets to precision mechanical parts, we help UAV companies turn CAD designs into production-ready components.

⚙️ 5 Design Mistakes That Increase Stainless Steel Part Costs

Small design decisions can create big manufacturing problems.

When designing stainless steel parts, engineers often focus on function — but overlook manufacturability.

These common mistakes can increase machining time, material waste, and production costs:

❌ Deep pockets → More difficult machining & longer tool paths
❌ Excessive material removal → Higher waste and machining time
❌ Ignoring internal geometry → Limits manufacturing options
❌ Complex features without DFM consideration → Higher production risk
❌ Designing without manufacturing feedback → Unexpected costs

✅ Better design = Lower manufacturing cost

With early Design for Manufacturing (DFM) review, engineers can:
✔ Reduce machining difficulty
✔ Optimize material usage
✔ Improve production efficiency
✔ Choose the right process — CNC machining or Metal 3D Printing

At Unionfab, our engineers help review your designs before production and identify cost-saving opportunities.
