Quality assurance (QA) is arguably the most important and yet one of the most challenging steps in 3D printing.   With 3D printing being increasingly used in high-performance industrial applications, the technology must consistently and reliably deliver high-quality parts with the properties needed to meet demanding applications. When it comes to metal 3D printing, however, this has been an ongoing challenge for many manufacturers looking to invest in the technology.   Today's article will be looking at the some of the key challenges companies face when trying to establish QA processes for metal ...

Support structures are one of the most important elements for successfully producing 3D printed parts. While a key advantage of 3D printing is its ability to create freeform and intricate geometries, much of the design freedom offered by 3D printing wouldn’t be possible without the use of support structures.   Supports are vital for preventing distortion and collapse within a part, among other uses. In this tutorial, we’ll be taking a deep dive into the world of support structures, the requirements for different technologies and how to minimise their usage.    What are ...

3D printing and CNC machining are the two most commonly used methods when it comes to prototyping and low-volume production. However, since both offer two very different approaches to manufacturing — one being additive and the other subtractive — identifying the right manufacturing method for your application is crucial for streamlining product development, achieving greater efficiency and, ultimately, higher-quality parts.   In this tutorial, we’ll look at the differences between 3D printing and CNC machining and share a few tips on how to pick the right method.   3D printing vs CNC When looking ...

As we've previously seen, 3D printing is rapidly expanding beyond prototyping into production. However, this transition is not without its challenges, with process repeatability and quality assurance being two issues cited by many manufacturers. It’s therefore unsurprising that manufacturers are looking for ways to optimise AM processes in the pursuit of greater repeatability and reliability.   Simulation software could be one way to achieve this. By enabling consistency and higher-quality parts, simulation is one tool that can further improve AM processes. We've therefore put together a list of 10 software companies offering innovative ...

When producing your FDM part, often the finished look matters just as much as the functionality. FDM parts are ideal for functional prototypes, low-volume end use parts and concept models. However, when printing your FDM parts, it’s important to know not only how the FDM production process works, but also how to achieve aesthetically-pleasing results in the post-processing stage. In today’s tutorial we’ll explore a few practical tips on how you can effectively finish your FDM parts — as well as key things to watch out for.   1. Remove any support structures ...

From its emergence in the mid-1990s, Binder Jetting has evolved into a key additive manufacturing technology with a variety of applications. From producing full-colour parts and prototypes to low-cost metal parts and sand molds for casting, Binder Jetting has found a wide use case within a range of industries.  In this tutorial we’ll delve into how Binder Jetting works, its benefits and limitations and practical tips on how you can get the most out of this technology.    How does Binder Jetting work? Binder Jetting technology works by using a print head to apply ...

Since its emergence in the mid-1980s, Selective Laser Sintering (SLS) has become one of the most widely used and versatile additive manufacturing technologies. SLS provides a host of benefits — not least because highly durable, lightweight parts can be produced in a matter of hours — and is used in a range of applications, from low-volume production to rapid prototyping. In this tutorial, we’ll take a closer look at how SLS works, its applications and how you can get the most out of the technology - and you can download our ...

Commercial 3D printing has not quite taken off at the rate one would have expected a few years ago. One reason for this is speed, with the majority of desktop 3D printers requiring hours to print a part. However, the development of a new desktop FDM 3D printer by a team of engineers at MIT may well have changed the game.   What's new? [caption id="attachment_2193" align="alignright" width="300"] Some of the objects printed on MIT’s new printer – Image: Chelsea Turner[/caption] While FDM technology is the most popular commercial 3D  printing system, it is ...

Following the success of formnext last week, AMFG is taking a closer look at some of the innovative companies that showcased at the Frankfurt trade fair. This week, we're speaking with Dr. Konstantin Rybalcenko, Development Manager at Additive Manufacturing Technologies, to talk about the company's revolutionary new technology, his experience at formnext and his thoughts on the future of additive manufacturing.   Post-processing is a critical stage in the additive manufacturing process - and yet, many post-processing techniques remain manual. As a result, post-processing is often a labour-intensive and costly element in the manufacturing ...
