The article, titled “3D Printing Myths I used to believe…,” is based on a video by Maker’s Muse. The video aims to debunk three common myths and misconceptions about 3D printing. The creator of the video has a vast experience of seven years in making 3D printing videos and over 10 years of using additive manufacturing technology. The article goes on to highlight the history of 3D printing technology, clarifying that it has been around for over 40 years and is more accurately referred to as additive manufacturing. It also mentions the key individuals who played a role in its invention, such as Hideo Kodama and Chuck Hall. Furthermore, the article addresses the misconception that ABS is always stronger or better than PLA, stating that there are various filament options available with different properties. Lastly, it discusses the importance of precise bed leveling in 3D printing and the potential issues with using a folded piece of paper to set the nozzle height. It suggests using a feeler gauge for a more accurate leveling and nozzle height adjustment process.

Myth #1: 3D Printing is a New Invention

Many people commonly believe that 3D printing is a new and groundbreaking technology that has recently emerged. However, this is a myth. In reality, 3D printing technology has been around for over 40 years. It is more accurately referred to as additive manufacturing, as it involves creating objects by adding layers of material on top of each other.

The invention of additive manufacturing can be credited to Hideo Kodama of the Nagoya Municipal Industrial Research Institute in Japan. In the early 1980s, Kodama developed two additive manufacturing techniques using resin that hardened when exposed to UV light. One of the methods he proposed used a mask to control UV exposure per layer, which is similar to the low-cost resin printers we use today.

While Kodama’s research and patent were published in 1981, it was Chuck Hall’s US patent in 1986 that truly started the 3D printing revolution. Hall’s patent paved the way for the release of the SLA-1 and the forming of 3D Systems Corporation, which is still one of the largest 3D printing companies in the world today.

It is important to understand the history of 3D printing and its pioneers to gain a better appreciation for the technology. The advancements made by individuals like Kodama and Hall have laid the foundation for the 3D printing technology we use today.

Myth #2: ABS is Always Stronger and Better than PLA

ABS (Acrylonitrile Butadiene Styrene) and PLA (Polylactic Acid) are two common types of filaments used in 3D printing. However, it is a misconception to assume that ABS is always stronger and better than PLA.

In reality, there are now various filament options available in the market with different properties. The strength and quality of prints depend on the specific filament brand and settings used. PLA, for example, has become increasingly popular due to its biodegradability and ease of use. PLA can produce high-quality prints with excellent dimensional accuracy.

Moreover, modern 3D printing filaments are often alloys, which are combinations of different polymers to achieve the best balance of strength and printability. Companies produce PLA alloys with improved properties, such as increased toughness, temperature resistance, and printability. It is crucial to explore different filament options and experiment with different materials to enhance your 3D printing experience and achieve the desired results.

Myth #3: Bed Leveling is the Same as Tramming

Another myth in the realm of 3D printing is the confusion between bed leveling and tramming. Bed leveling is often incorrectly referred to as tramming, leading to misunderstandings within the 3D printing community.

Bed leveling in 3D printing refers to the process of adjusting the print bed to ensure proper adhesion and layer height. It ensures that the bed is parallel to the printer’s nozzle and helps in achieving a successful print with accurate layer height.

Tramming, on the other hand, is all about ensuring that the printer frame is square and level. It involves aligning the printer’s gantry to the XY table and making sure that the vertical walls of the prints are straight and correctly aligned.

Both bed leveling and tramming are crucial for successful 3D prints, but they serve different purposes. Bed leveling ensures the print bed’s proper alignment with the nozzle, while tramming ensures the printer’s overall frame is square and level.

Understanding the distinction between bed leveling and tramming is essential for maintaining the accuracy and quality of your 3D prints.

Myth #4: Using a Folded Piece of Paper for Nozzle Height

Using a folded piece of paper to set the nozzle height is a common method employed by many 3D printing enthusiasts. However, relying solely on this technique can result in incorrect nozzle height and failed prints.

When using a folded piece of paper, the user places it between the nozzle and the print bed and adjusts the height until they feel slight resistance. This is done to create a specific gap between the nozzle and the bed, which determines the first layer height. However, there are a few limitations to this method.

Firstly, a 3D printer does not start the first layer at zero height. It starts at the predetermined height set in the printer’s software, typically around 0.15 or 0.2 millimeters. By using a folded piece of paper to set the nozzle height, the user may inadvertently set the height too far from the zero position, resulting in improper adhesion and failed prints.

To achieve accurate nozzle height, it is recommended to use a feeler gauge instead of relying on a folded piece of paper. A feeler gauge is a precision measuring tool with multiple thicknesses that can be used to set the nozzle height with greater accuracy. Investing in a feeler gauge can significantly improve the quality of your 3D prints by ensuring a perfectly leveled bed and nozzle for a flawless first layer.

By debunking these myths, we can gain a better understanding of 3D printing technology and be more informed users. It is crucial to stay up-to-date with the latest advancements and techniques in the field to achieve the best results with your 3D prints. Experimenting with different materials, filaments, and tools can further enhance your 3D printing experience and open up new possibilities.
