Top 5 3D Printing Myths and Misconceptions

Summary

In this video, Angus from Makers Muse debunks five common myths about 3D printing. He clarifies that 3D printing has been around since the 1980s, highlighting its evolution and the limitations of current technologies. Angus explains that while 3D printing offers vast possibilities, it isn't as simple as creating anything from imagination. He discusses the complexities of 3D scanning and emphasizes that modern materials have made 3D printed items practical for real-world use. Finally, he reassures viewers that 3D printers have become more affordable, making the technology accessible to enthusiasts.

Takeaways

• 😀 3D printing technology has been around since the early 1980s, not just a recent development.
• 😀 Hideo Kodama was a pioneer in 3D printing, with significant contributions to its early techniques.
• 😀 FDM (Fused Deposition Modeling) is the most common technology used in desktop 3D printers today.
• 😀 3D printing cannot produce just anything; it has specific limitations, especially with multi-material and full-color printing.
• 😀 Designing 3D models is essential, which poses a challenge for many potential users.
• 😀 3D scanning is complex and often requires post-processing to correct inaccuracies in scans.
• 😀 Some materials, like reflective or transparent surfaces, are difficult or impossible to scan accurately.
• 😀 Modern materials have greatly improved the practicality of 3D printed parts for real-world applications.
• 😀 Affordable 3D printers are now available, significantly reducing the entry cost for enthusiasts.
• 😀 The perception of 3D printing as expensive is outdated, with many reliable options under $500.

Q & A

What is the historical origin of 3D printing?

3D printing has been around since the early 1980s, with Hideo Kodama being one of the first to experiment with the technology that led to what we now know as stereolithography.

What is FDM and when was it developed?

Fused Deposition Modeling (FDM) is a 3D printing technology developed in the late 1980s and commercialized by Stratasys in the 1990s.

Can 3D printing produce multi-material objects easily?

No, multi-material printing remains a significant challenge in 3D printing, with current technologies not producing these models very well.

What are some limitations of 3D scanning?

3D scanning can be complex and often requires post-processing to correct details. Scanners also struggle with reflective, transparent surfaces, and details like threads may not be captured accurately.

Are all 3D printed objects fragile?

No, modern materials have improved the durability of 3D printed objects. For example, PolyMaxx PLA has a much higher impact resistance compared to standard PLA.

What advancements have been made in 3D printing materials?

Advancements include high-temperature resistant materials, such as Proto Pasta's high-temperature PLA, which can withstand temperatures above 120 degrees Celsius.

How have the costs of 3D printers changed over the years?

The cost of 3D printers has significantly decreased, with affordable models available for under $400, making them accessible to more consumers.

What is a practical example of a 3D printed object in real-world use?

The Prusa i3 Mark 2 is a practical example, as it is comprised almost entirely of 3D printed components, demonstrating the viability of 3D printing for functional applications.

What is a common misconception about the ease of 3D scanning?

A common misconception is that 3D scanning works like a photocopier. In reality, it is a complex process that often requires additional work to achieve accurate results.

Why is 3D design considered a barrier for many potential users?

Many people find 3D design challenging, as it requires skills and knowledge that may not be readily accessible to those new to 3D printing.
