]]>304 vs 316 Stainless Steel: What’s the Difference and Which Should You Use?
Stainless steel is one of the most widely used materials in manufacturing and engineering — known for its strength, corrosion resistance, and sleek appearance. Among the many types of stainless steel, 304 and 316 are by far the most common. But how do they differ, and when should you choose one over the other?
Let’s explore the differences between 304 and 316 stainless steel in terms of composition, properties, applications, and cost.
Composition Difference
The key difference between 304 and 316 stainless steel lies in their chemical makeup:
Element | 304 Stainless Steel | 316 Stainless Steel |

]]>Top 5 Design Tips for Stronger 3D Printed Parts
Whether you’re creating prototypes or functional end-use components, ensuring strength and durability in your 3D printed parts is essential. Good design can significantly enhance part performance, reduce failure rates, and make your prints more reliable. Here are the top 5 design tips to help you get stronger, more resilient 3D printed parts.
- Optimize Print Orientation
Layer adhesion is typically the weakest point in any 3D printed part. To maximize strength, orient your part so that the layers run perpendicular to the direction of the applied forces. For example, if the part will endure vertical stress, consider printing it lying down so the layers stack horizontally relative to the stress.
Pro Tip: Use simulation tools to predict stress points and align your model accordingly.
- Use Fillets Instead of Sharp Corners
Sharp corners create stress concentration points which can lead to cracking. Adding fillets (rounded edges) not only improves the strength by distributing stress more evenly but also enhances the printability by reducing potential printing errors.
Pro Tip: A fillet radius of 1-2 mm is often sufficient for improving part integrity.
- Increase Wall Thickness and Infill Density
One of the simplest ways to strengthen your part is by adjusting wall thickness and different infill settings. A thicker shell and higher infill percentage will create a sturdier structure. However, this also increases material use and print time, so find a balance based on your part’s function.
Pro Tip: For functional parts, use at least 2 mm wall thickness and 50% infill or higher.
- Add Ribs and Gussets for Structural Support
Instead of just increasing infill, adding structural features like ribs (vertical walls) and gussets (triangular supports) can reinforce weak sections without significantly increasing weight or print time. These features are especially helpful in load-bearing areas.
Pro Tip: Integrate ribs along flat surfaces or near holes to reduce flex.
- Choose the Right Material
Material selection is key. PLA might be easy to print, but it lacks the toughness of materials like PETG, ABS, or Nylon. If you’re printing functional parts that will be stressed, exposed to impact, or require flexibility, choose a material that meets those needs.
Pro Tip: Consider carbon fiber-reinforced filaments for high-stress, lightweight applications.

SLS prints often have a powdery or rough texture that must be smoothed for optimal electroplating results.
- Clean the Print: Remove excess powder from the surface using compressed air or brushing.
- Sanding: Use progressively finer sandpaper (follow 400-600-800-1200-2000) to smooth the surface. For a polished finish, apply a polishing compound after sanding.
- Wash and Dry: Use isopropyl alcohol to remove dust and oils, then let the print dry completely.
Step 2: Apply a Conductive Coating
Since nylon is non-conductive, applying a conductive coating is crucial for the electroplating process.
- Choose the Right Coating: Graphite-based or silver conductive paints work well for nylon.
- Apply Evenly: Spray or brush on the coating, ensuring full coverage, especially in intricate areas.
- Dry Thoroughly: Allow the conductive layer to cure as per the manufacturer’s instructions.
Step 3: Set Up the Electroplating System
Prepare your electroplating bath according to the chosen metal.
- Electroplating Solution: Mix the solution as directed, ensuring the concentration matches the metal you’re using (e.g., nickel, copper, or gold).
- Attach Electrodes:
- Anode: Use a metal electrode of the same type as your plating solution (e.g., copper for copper plating).
- Cathode: Connect your prepared SLS print to the negative terminal of the power supply.
- Immerse the Print: Submerge the part in the electroplating bath, ensuring all conductive areas are covered.
Step 4: Electroplate the Part
- Adjust the Current: Set the power supply to the appropriate voltage and current for your plating process. A lower current ensures a smoother, more uniform coating.
- Plating Time: Monitor the process, as plating time varies depending on the desired thickness.
- Rotate if Needed: For complex shapes, rotate the part periodically to ensure even coverage.
Step 5: Post-Plating Finishing
Once the desired metal layer thickness is achieved, carefully remove the print from the bath.
- Rinse Thoroughly: Use clean water to rinse away residual solution.
- Polish the Surface: Use a polishing compound to enhance the metallic shine.
- Optional Sealant: Apply a clear protective coat to prevent tarnishing or corrosion.
Tips for Success
- Start Small: Practice on test pieces before plating a critical part.
- Monitor Closely: Overplating can lead to uneven surfaces or cracks.
- Experiment with Metals: Copper is a great base layer; additional layers of nickel or gold can enhance the finish.
Applications for Electroplated SLS Nylon Parts
Electroplating expands the range of applications for SLS nylon prints:
- Functional Prototypes: Stronger and more durable parts for testing.
- Decorative Items: High-quality metallic finishes for display models and ornaments.
- Conductive Components: Electroplated parts for electronics or RF shielding.
Challenges and Considerations
- Porosity of Nylon: While helpful for adhesion, excess porosity can result in uneven plating. Proper sealing with conductive paint helps address this.
- Cost: Electroplating involves additional materials and equipment, so factor this into your project budget.
- Safety: Work in a well-ventilated area and follow safety guidelines for chemicals and electricity.
