additive

There has been an increasing tendency to move towards additive manufacturing (AM) in recent years. This is due to the process’ enhanced ability to manufacture complex geometries, customised parts, and intricate designs in manufacturing work. However, the secret sauce in ensuring that AM parts reach their full potential is during the post-processing phase. This is because, post the fabrication phase, there may be subtle imperfections which if not attended to during post-processing, can compromise the functionality of the part or diminish its aesthetic value. This article dives into the significant role various post-processing techniques play and how carefully planned post-processing can be the difference-maker in AM.

Mass Finishing

Advanced mass-finishing post-processing techniques are designed to improve the surface finish of AM parts. These methods, which include vibratory finishing, heat induction bending services and centrifugal disc finishing, use media and compounds in a contained environment to polish and smooth parts. Advanced mass finishing plays a crucial role in the post-processing phase of AM, bringing several key benefits to the table. One of its primary advantages is the assurance of consistency and uniformity. Regardless of the diverse geometries of parts, mass finishing provides a consistent finish to each, ensuring that every piece meets the desired standard. Furthermore, this process significantly improves the surface quality of the parts. This enhancement is not just a cosmetic one; a better surface finish often translates to improved functional performance across various applications such as pressure vessels. Whether it is reducing wear and tear in mechanical components or amplifying the aesthetic allure of consumer products, the benefits are tangible and manifold.

Additionally, scalability remains one of the standout attributes of advanced mass finishing. Especially pertinent for higher volume production, this technique is adept at managing multiple parts simultaneously. By doing so, it not only maintains the quality across the board but also guarantees a high throughput, making it an indispensable tool for industries aiming for both quality and quantity in their manufacturing endeavors.

Shot Blasting

Shot blasting is another post-processing technique wherein tiny metallic or non-metallic shots are propelled at high velocity onto the AM part’s surface. This not only cleans the surface from contaminants but also prepares it for subsequent steps like painting or specialized coatings. Shot blasting is a pivotal link to finished fabrication, characterised by its speed and efficiency. The method can swiftly clean and prepare surfaces, positioning it as an ideal choice for expansive AM operations where time is of the essence. Beyond mere cleansing, shot blasting plays a pivotal role in surface profiling. The precision of the process ensures that the desired surface roughness is achieved, setting the stage for subsequent coatings. This meticulous preparation guarantees better adhesion of these coatings, which is integral for many applications.

Furthermore, the longevity imparted by shot blasting cannot be overlooked. The process meticulously removes both imperfections and contaminants from the parts. This thorough cleansing not only enhances the immediate appearance and functionality of the parts but also contributes to their long-term durability. As a result, shot-blasted parts often boast a prolonged lifespan, offering users more value and reliability from each component, reaffirming the importance of this post-processing technique in the AM landscape.

Conclusion

The growth and adoption of AM in industries worldwide have spotlighted the importance of a robust and efficient process chain. As AM continues to redefine manufacturing paradigms, businesses must recognize the pivotal role of advanced mass finishing and shot blasting in optimizing efficiency and accelerating production. As the saying goes, “A chain is only as strong as its weakest link.” In the world of AM, a well-thought-out post-processing strategy could very well be the strongest link in the chain!
