3D printing is a natively digital process. Software is involved in every step, gathering data about the design, manufacture and post-processing. Out of this wealth of information, the Internet of Things (IoT) data is particularly useful. Organizations can leverage IoT, or the information about their 3D printers, to improve their performance and productivity in real time. In this blog, we take a look at what 3D printing IoT data stands for and how to use it in operations.
3D printers have become a mature, production-ready technology in the last decade. Today many machines are connected to an IoT device and continuously generating information.
What exactly this data includes depends on the 3D printer’s model and vendor, but the term generally refers to the printer’s vital signs that are captured by sensors, such as:
This is information about the state of the printer, be it connected and producing, or on standby. For example, if printing is in progress, IoT data will include the percentage of the build completion.
This includes airflow information, compressed air consumption, temperature (hot ends, chamber or print bed), filter status, speed, and more.
Sensors provide information about safety controls such as whether the machine’s doors are opened or closed.
This basic IoT information, such as the progress of a build, the temperature, humidity, and airflow, can be combined into a specific key performance indicator (KPI) which an organization can track to understand overall machine performance and productivity.
Engineers can use this to see the completion time and plan the next actions, or to even increase the efficiency in their production.
If you want to understand what real-time IoT data can do for your 3D printing operations, think of the following scenario. You launch a print job on a Friday, and the following Monday you discover that the job has failed due to a problem with the printer or the slice file. You're dealing with material waste in addition to the time lost while the machine was idle.
Now imagine that you can learn about the problem as soon as it emerges, and immediately implement changes to get the printer up and running again. That’s what IoT makes possible.
With a platform like Oqton’s Manufacturing OS users can configure dashboards to overlook machine performance and print statuses. They can use this data to identify opportunities for efficiency improvements or to prevent failed print jobs.
Users can spot potential issues and act immediately by setting up alerts. For example, if someone uses a material with a machine that is not specified for the print job, they will receive a notification.
Alerts allow users to monitor a machine even when working remotely. They can get an email or text message when Oxygen levels exceed the target or when the recoater is too slow, allowing them to act before the print has failed.
In the case of test prints, monitoring can lead to reducing the number of iterations and minimizing the risk of serious damage to printers and parts.
By using IoT data in this way, manufacturers will improve the productivity of their 3D printers or post-processing workstations. This works for any type of technology and material, whether it’s powder-based, filament-based, polymer, metal, or composite.
There are numerous parameters we can track when it comes to IoT data, and every organization knows best what's most relevant for them. What they all have in common is the need for dashboards that are easy to configure, as this allows them to get quick access to information that is most important for a specific print job, and to keep on top of their KPIs. The Manufacturing OS is highly configurable, enabling companies to autonomously adjust their dashboards without having to hire external consultants.
The possibility to overview all machine data in a single MES is game-changing. This means users get constant feedback on successes or failures. Since the dashboards are always up-to-date, you have a broad overview of their performances and capabilities and can make better planning decisions.
Additionally, companies can use the data they collect for smarter, AI-based decision-making. For example, the Manufacturing OS’s AI suggests optimal ways of nesting parts on a build plate, so that engineers spend less time on build preparation time and increase their daily production.
Users can get an even more efficient industrial automation solution by connecting IoT and Direct Machine Control (DMC). These systems analyse the data that the IoT-connected devices provide and can change machine operations based on the results. For example, the DMC can start, stop or pause a print job remotely.
DMC systems have led to significant improvements in manufacturing efficiency and productivity because the precise control of machines reduces waste and increases throughput.
Any manufacturer can benefit from having real-time data on printer performances and material usage. It allows them to reduce downtime, check machine availability faster and respond quickly to changes in demand. Combining all the data will allow them to measure their overall equipment effectiveness (OEE) and improve them if needed.
However, IoT data is particularly useful to highly regulated industries, such as energy and medical. Organizations in these segments must meet strict regulatory requirements about the traceability of their products, and to comply, they must track their machines and print jobs meticulously. IoT data allows them to identify and address any issues that arise during the printing process and to ensure they meet these requirements.
More and more manufacturers are recognizing the value of having real-time access to IoT data, and seeking out solutions. A challenge that some come up against is that some machines still can’t be connected. In such cases, specific API integrations will need to be developed.
Another disadvantage is that a limited number of parameters are transmitted in real-time. Therefore, data visualization and data optimization can provide only limited insights into business operations.
Since the 3D printing market is projected to grow massively in the next years, many new machine vendors will enable the connection on their printers, capturing more machine data and enabling predictive analytics.
IoT has revolutionized additive manufacturing.Real-time machine monitoring gives manufacturers more control over the process, and the ability to make it more efficient, reliable and cost-effective.
