Nexa3D collaborates with Headmade Materials to facilitate the use of metal 3D printing on QLS systems.


Nexa3D and Headmade Materials have joined forces to bring metal 3D printing to their QLS series of printers. The collaboration introduces ColdMetalFusion, a new metal 3D printing process that combines laser sintering with powder metallurgy techniques. This partnership enhances the performance of Nexa3D’s fast-cycle QLS series and allows customers in industries like aerospace, automotive, and healthcare to quickly and precisely create metal components. ColdMetalFusion offers a wide range of material options, including titanium, stainless steel 316L, stainless steel 17-4PH, and tool steel M2. Headmade Materials, a key member of the alliance, works with other industry experts to redefine large-scale additive manufacturing. The ultimate goal of this collaboration is to revolutionize industrial 3D printing by creating a comprehensive end-to-end solution. Other members of the alliance include LÖMI, MIMplus, element22, PresX, Farsoon, Rösler’s AM Solutions, and Sintratec. ColdMetalFusion combines the design flexibility and speed of polymer laser sintering with the robustness and cost-efficiency of powder metallurgy, allowing for the production of high-quality and cost-effective metal parts. The technology also offers high performance, precise repeatability, and scalability, making it suitable for both small-batch and large-scale production. The QLS series of 3D printers from Nexa3D, in partnership with Headmade Materials, provides an all-in-one solution for metal manufacturing, including services, equipment, materials, software, and industry expertise. The printers utilize a patented metal powder coated with a thin polymer layer to facilitate bonding during the sintering process. Once the parts are formed, Nexa3D’s validated processes for debinding and sintering remove the polymer, leaving fully metallic components. The QLS 230 and QLS 236 models are zero-waste printers that allow manufacturers to recycle and reuse powder from other SLS equipment, resulting in cost savings. The QLS 230 model can produce metal parts with properties similar to those made through traditional metal injection molding but at a faster pace and potentially at a lower cost. The partnership between Nexa3D and Headmade Materials not only expands the capabilities of 3D printing but also offers material versatility and a cost-effective pathway for serial production. This innovative process eliminates common restrictions in metal manufacturing and reduces post-processing steps, waste, and material costs. By leveraging this technology, industries can benefit from faster, more precise, and more cost-effective production of metal components.

Are you tired of receiving spam emails and notifications from various 3D printing vendors? Do you find it overwhelming to keep up with the latest news in the industry? We understand your frustration and want to offer a solution that will help streamline your experience.

In today’s blog post, we will be discussing the importance of eliminating redundant support structures in the 3D printing industry. However, we want to take a different approach and focus on delivering valuable content without bombarding you with unnecessary information and offers from third-party vendors. Let’s dive in!

Support structures play a crucial role in ensuring successful 3D prints. They are temporary structures that are created to provide stability and prevent deformities during the printing process. While necessary in some cases, support structures can be time-consuming, wasteful, and add complexity to the overall printing process.

However, staying informed about the latest advancements, news, and trends in the 3D printing industry is equally important. That’s why we have decided to offer a concise and curated source of information that keeps you updated without overwhelming you.

Our aim is to provide you with unbiased and valuable content that helps you stay ahead in the 3D printing game. We believe in quality over quantity, which means we will only share the most important and relevant news and insights, without bombarding you with redundant information or irrelevant offers from third-party vendors. Say goodbye to overflowing inboxes and say hello to a clutter-free 3D printing experience!

By eliminating redundant support structures and unnecessary information, we are committed to streamlining your 3D printing journey. Our blog will be your go-to resource for the latest industry trends, technological advancements, and expert advice.

But how can you stay updated without missing out on key information? We have got you covered! Simply subscribe to our newsletter and receive carefully curated content straight to your inbox. Rest assured, you won’t be bombarded with spam or irrelevant offers. Our newsletter is tailored to keep you informed and inspired, without overwhelming you.

In conclusion, staying updated with the latest news and developments in the 3D printing industry is important, but it shouldn’t come at the cost of your sanity. By eliminating redundant support structures and unnecessary information, we are committed to delivering a streamlined and valuable experience for all 3D printing enthusiasts.
