3D Metal FDM? With Paste? Wait, What? Rapidia 3D at AMUG 2023

Welcome to our deep-dive exploration of the world of metal 3D printing. Today, we're featuring Rapidia, a front-runner in the industry that's making waves with their unique, paste-based metal 3D printing technology. This video takes you inside their innovative process, giving you an in-depth understanding of what sets Rapidia apart from other 3D metal printing companies like Markforged and Desktop Metal.

In this video, we explore Rapidia's two-step process for 3D printing, using a paste rather than a filament, somewhat similar to the processes of Markforged and Desktop Metal. We discuss how their technology leverages metal powder, water, and a minimal amount of binder to create intricate designs with impressive efficiency.

Our time at the AMUG 2023 Expo was awesome, as we saw firsthand how Rapidia's 3D metal printing process allows for faster creation and centering. Get an up-close look at their metal 3D printing process, the end-to-end time savings they offer, and the nearly pure metal output their technology achieves.

We also get into the specifics of Rapidia's material extrusion metal and their game-changing low shrinkage factor, comparing it to other industry players. Plus, we examine a variety of finished products to illustrate the level of detail and design Rapidia’s metal 3D printing process can achieve – things that traditional machining might not always be able to accomplish.

Find out how Rapidia stands out among other 3D metal printing companies with its ability to print multiple parts separately and then merge them together before centering, leading to seamless metal parts with optimal print orientations for different features.

Our video also covers Rapidia's finishing capabilities and the different types of finishes possible with their 3D printing process, from as-printed parts to machined, sanded, and polished finishes.

Stay till the end to see a tour of Rapidia's printer, with a detailed explanation of the build volume, material paste, and the precision extruder head that sets them apart from other 3D metal printing companies.

Whether you're a 3D printing enthusiast, a professional in the field, or just curious about the future of metal manufacturing, this video is packed with insights into the cutting-edge world of 3D metal printing. If you're researching 3D metal printing, considering solutions from Markforged or Desktop Metal, don't miss out on what Rapidia has to offer.
