Expert Insights: The Future of Automation in 3D Printing with Henrique Carvalho

Recently, we had the opportunity to speak with Henrique Carvalho, a professional with extensive experience in the automotive industry and in the 3D printing sector. The conversation was a deep dive into the technical challenges and market opportunities for our automation system.

Here are the key points and main takeaways from this interview.

1. The Materials Challenge

One of the most surprising pieces of feedback concerned material compatibility.

While we initially thought PLA would be the easiest material to automate, Henrique warned of a common problem:
PLA tends to stick very strongly to the print bed.

Interestingly, engineering materials such as:

• ABS
• ASA
• Nylon

are often easier to automate, because they release naturally from textured build plates as the bed temperature drops.

2. Mechanics and Durability

We also received a crucial tip about the removal motion.

To avoid damaging the printer, Henrique suggested the system should:

• Use the printer’s aluminum structural frame to push the parts
• Avoid applying force directly to the extruder

Applying force to the extruder can, over time,:

• damage bearings
• affect the machine’s calibration
• reduce the equipment’s lifespan

3. Computer Vision and Quality Control

Our idea of using computer vision to separate good parts from defective ones was validated, but with some important caveats.

Lighting and Shadows

Comparing 2D images can be challenging due to:

• color variations
• shadows
• surface reflections

Hardware

The built-in cameras in many entry-level printers may not provide sufficient quality.

For that reason, Henrique recommended:

• external cameras
• dedicated lighting systems
• a more controlled and consistent visual environment

4. Product Strategy: Beyond the Kit

Henrique challenged us to think more ambitiously.

Instead of only offering an automation kit, we could provide a turnkey solution that includes:

• Shelving or rack systems to optimize space
• Structures that ensure repeatability and organization
• Spools holders for larger filament rolls (3kg to 5kg)

This would allow a small factory or print farm to operate for several days truly autonomously.

5. Focus on High-End Equipment and Reliability

The most strategic lesson was about positioning the product in the market.

Henrique recommended not focusing development on entry-level or low-cost Chinese printers.

According to him:

• People who buy those machines do so mainly for the price
• That audience rarely invests in additional automation systems

The recommendation was clear:

Focus on high-end, reference printers, such as Prusa.

Users who already invest in robust, reliable equipment are exactly those who:

• value efficiency
• seek automation
• have the means to invest in professional solutions

As he emphasized:

It is often more strategic to sell a robust solution with added value than to try to compete on price alone.

Conclusion

This interview was a reality check, but also a great encouragement.

By refocusing on high-end printers and on integrated solutions for space and production management, we believe our system can evolve from a simple accessory into:

An essential tool for industrial production in 3D printing.
