Here Are The Challenges Faced By Additive Manufacturing (3D Printing) Process

Additive manufacturing or 3D printing with polymers has brought about a revolution in various industries by enabling the production of complex and customized components. 3D printing technology has numerous advantages such as reduced lead time, lower material waste, increased design flexibility and a lot more. However, despite these benefits, additive manufacturing with polymers has its fair share of challenges. In this article, let’s dive into these challenges and how to combat them.

Hurdles Disrupting Additive Manufacturing

Inconsistent Quality – One of the major drawbacks of 3D printing is the inconsistent quality of printed parts, which can vary depending on the printer and polymer material used. This inconsistency can be attributed to several factors, such as:

·   Printer’s calibration

·   Polymer material’s properties

·   Printing process settings

As a result, the quality and accuracy of the printed parts can vary, which can affect their performance and functionality.

Structural Strength – Printed components using additive manufacturing with polymers typically have lower structural strength than those produced using traditional methods such as injection moulding or CNC machining. This can make them unsuitable for applications requiring high-stress loads, such as certain automotive or aerospace components.

Solutions To Ongoing Challenges

• New Polymer Materials – Advancements in material science and engineering have led to the development of new polymer materials specifically designed for additive manufacturing, which offer improved mechanical properties and greater strength. New polymer materials specifically such as polyetherimide (PEI) and polyphenyl sulfone (PPSU), have been developed to improve mechanical properties, strength, and heat resistance. Switching to these materials for 3D printing can ensure product durability.

• Improvement & Innovation – Printing processes and equipment are also being improved to achieve higher accuracy and consistency in the printed parts. Furthermore, innovative design techniques such as lattice structures can be employed to optimize the strength and reduce the weight of printed components, making them more viable for high-stress applications. With the development of new materials and improvements in printing processes, it has the potential to produce parts with properties comparable to those manufactured using traditional methods, while also offering unique design possibilities and cost savings.

Insight

Additive manufacturing (3D printing) with polymers has ushered in a new era of manufacturing. With ongoing efforts in research and development, the future of additive manufacturing with polymers looks promising. As 3D printing technology upgrades, we can expect to see even more innovative 3D printing applications across various industries, further transforming the way  3D printing machines produce complex and customized components.
