The Correct Orientation to Print Boxes | Design for Mass Production 3D Printing

Summary

The video discusses an alternative orientation for 3D printing enclosures to maximize strength and minimize support material. Rather than printing vertically or horizontally, the recommended approach is to print diagonally at a 45 degree angle. This creates durable parts with no weak layer lines, reduces overhangs and the need for supports, and enables designing functional features like thick walls and flanges. The diagonal orientation also allows adding designed support structures that are easily removable. Further customization like textured surfaces can provide aesthetic benefits. Overall, this method facilitates affordable, custom, and durable enclosures superior to off-the-shelf solutions.

Takeaways

• 😀 There are 3 main ways to 3D print an electrical enclosure - vertically, horizontally, or diagonally.
• 👍🏻 Printing diagonally creates a strong, durable part without needing much support material.
• 🔨 Design enclosures with thick walls and flanges for sturdy screw points.
• 🛠 Use 3D printing to create custom enclosures with any geometry.
• 💡 Add an interface ridge so the lid can mount securely.
• ✂ Design support structures that are easy to break off.
• ⚙️ Use a 45° angle to print without overhangs and prevent splitting.
• 🖼 Add noise to the print for a beautiful textured surface.
• 🔧 Print the lid at a shallower 35° angle to fit the enclosure.
• 💰 3D printed enclosures are affordable even in high volumes.

Q & A

What are the two most common orientations for 3D printing electrical enclosures?

The two most common orientations are printing vertically or horizontally/flat on the print bed.

What are some downsides of printing enclosures vertically?

Printing vertically can require a lot of support material inside the enclosure which is difficult to remove. This adds time and cost for post-processing.

What are some benefits of 3D printing enclosures versus traditional manufacturing methods?

3D printing allows for thicker features, custom geometries, and less material waste compared to traditional manufacturing methods like plastic injection molding.

How can the design be optimized for 3D printing?

The design can utilize thick walls, flanges, and screw mounts. The geometry can be fully customized without the constraints of traditional manufacturing.

What is the recommended orientation for 3D printing enclosures?

Printing the enclosure diagonally at a 45 degree angle allows for clean support removal and maximum strength in all directions.

How are supports designed when printing diagonally?

Designed supports are used rather than autogenerated supports. These consist of fins and ribs spaced 0.5-1mm from the part to allow clean removal.

How does diagonal printing improve strength?

Diagonal printing creates maximum strength through all features of the part. Vertically or horizontally can create weak splitting planes.

How is the lid designed to fit the enclosure?

The lid has an interior lip that mounts onto the thick outer edge of the enclosure opening.

What finishing was done on the enclosure exterior?

A bit of noise/texture was added to the exterior walls to create a beautiful textured surface finish.

What are the benefits of 3D printing this type of enclosure?

3D printing allows for affordable, durable, and customizable enclosures with features beyond off-the-shelf solutions.
