Data-Driven 3D Printers: The Real Game-Changers for Manufacturing? Artificial intelligence and machine learning take additive to the next level.

Connected 3D printers can use collected data for artificial intelligence-powered automation. During each print job, 3D printers produce large quantities of data that are sent to and stored in the cloud. This data can help businesses make decisions about which parts to print and how best to print them, while improving the quality of print jobs.


Machine learning can optimize hardware, automatically enhancing 3D printers through software updates to increase printing speeds and improve resolution. AI can help businesses determine which parts, when produced in-house through additive manufacturing, will have the biggest impact on their bottom line. It can use digital catalogs of parts and detect which specific parts are the best candidates to be printed through various additive manufacturing techniques.

3D printers can use machine learning to automatically generate tooling jigs or fixtures to hold the parts they print.  AI-based optimizations  are used during the design stage of new parts — simulating how the digital design for a part, once printed, will perform under specific loads. AI is also employed in additive manufacturing to detect print failures (proactively pausing prints when needed), and to inspect parts as they’re being printed to ensure quality and conformance.

A Closed Loop
The same hardware out in the field is consistently learning, improving and getting smarter with every over-the-air update. As providers advance the quality of information collected during fabrication and build modes of collecting data about how each 3D printed part does its job on the field, manufacturing technology approaches a fully automated “closed-loop” printing process: One that can simply be presented with a real-world manufacturing problem to solve, and then design and build the part using the specific digital fabrication technology that makes the most sense given the defined time, cost, and performance constraints.

This smart, closed-loop automation of fabrication can substantially increase outputs and production speeds. And while additive manufacturing inherently streamlines the process of building parts, each savvy application of data collected by the printers can streamline distinct points within the additive manufacturing process.

Productivity of 3D Printing - Additive Manufacturing  - High-speed 3D printing and the expanding material choice 


3D Printer manufacturers are focusing on developing technologies that support higher production volumes, and materials that enable advanced AM applications.  As a result, on the hardware side,  the rise of binder jetting and multi-laser powder bed fusion for metals and vat photopolymerisation processes for plastics is occurring. Materials manufacturers are increasingly focusing on high-performance materials, including advanced alloys and composites. 

The introduction of high-speed polymer AM technologies has significantly boosted the growth of 3D printing in dental. As estimated by the market research firm SmarTech, the AM dental and medical industry has topped $3 billion. Over 70% of dental labs in the US are predicted to own 3D printing technology by the end of 2021, with dental 3D printing becoming a $9.2 billion industry in the next five to seven years. 

Metal powder bed fusion: Metal 3D printing encompasses many technologies, but one of the most matured among them remains metal Powder Bed Fusion (PBF). Key market players are launching solutions for automated and integrated production. They offer a high level of automation in a bid to maximise efficiency and reduce the amount of manual labour required.  Thanks to these developments, laser PBF has found its way into many industries and applications. One industry that has been  adopting metal PBF is aerospace. Today, metal PBF 3D-printed parts are powering crucial aircraft and spacecraft systems like engines. This is where the technology’s key capabilities — the production of complex parts with simplified assembly and less material waste — truly shine. 

Research at VTT & Aalto University


New launches of Additive Manufacturing systems with enhanced productivity (e.g. SLM Solutions, ExOne, Nexa3D, Voxeljet, EOS Systems), and a growing number of software companies in the field of AM boost the hope for applying AM technologies for a larger share of components.  We at VTT & Aalto University are supporting productivity improvement of AM and have been developing and testing promising bio-based engineering materials produced from sustainable sources within the ValueBioMat project. We are focusing on advances in material science and innovation that are needed to get prepared for the future of AM, with productivity in line with sustainability.

Filtration technology boosts metal additive manufacturing ( powder-bed fusion process) productivity

Sept. 16, 2021

BOFA International (Poole, UK) has developed an innovation  that makes the exchange of filters in metal additive manufacturing processes safer, faster, and better for productivity. The laser powder-bed fusion process used in metal additive manufacturing needs filters. When new filters are needed for these systems, equipment has to be shut down and moved to a safe area for the saturated filters to be removed and replaced by operatives wearing full PPE—up until now. The new standalone AM 400 system’s technology enables the filters to be exchanged on site without risking a thermal event. The BOFA’s AM 400 filters are contained within a separate housing with a robust seal, enabling filter exchange to be completed quickly and safely without isolating the additive manufacturing equipment. This will reduce downtime of the equipment and  increase productivity.

K. F. Graff, M. Short and M. Norfolk
Edison Welding Institute, Columbus, OH 43221
2010

To extend current ultrasonic additive manufacturing (UAM) to advanced materials, higher
speeds and larger parts, it was essential to greatly increase the process ultrasonic power. EWI,
with Solidica™, several industry, agency and academic partners, and support of Ohio’s Wright
Program, have developed a “Very High Power Ultrasonic Additive Manufacturing System” that
greatly extends current technology. A key part was the design of a 9.0 kW “push-pull”
ultrasonic system able to produce sound welds in materials such as Ti 6-4, 316SS, 1100 Cu and
Al7075. The VHP system can fabricate parts of up to 1.5m x 1.5m x 0.6m.

Technology Adoption
Partnering in Technology Development for Productivity Improvement

Volkswagen  adopts the latest 3D printing technology, the "HP Metal Jet" process, which simplifies and speeds up metallic 3D printing. The process improves productivity by a simply staggering 50 times compared to other 3D printing methods for some components.

This process produces production-ready components for mass production applications in the automotive industry for the very first time. Volkswagen has closely partnered with printer manufacturer HP and component manufacturer GKN Powder Metallurgy in development for mass production use. The  new process was demonstrated at the International Manufacturing Technology Show (IMTS) in Chicago this week.

Volkswagen's Head of Technology Planning and Development, Dr. Martin Goede said that  we are relying on state-of-the-art technologies to ensure a smooth and fast production and  3D printing will play an  important role in manufacturing of individual parts.

Productivity Drivers - 3D Printing


The output per unit time of  3D printer depends on

–Size of extrusion nozzle opening: ; The bigger the opening the more the material flow.

–Size of part to be printed. More volume, more time

–Part orientation on the build bed. X-Y orientations can usually be built faster than parts set up to build in the Z orientation.

–Complexity of part to be printed. Parts with many angles, curves and other geometric features will take longer to build than a straightforward box type shape.

–Material choice. In extrusion systems, every material flows at a different rate.

–Type of laser used in powder-bed systems.

–Type of material used in powder-bed systems. Plastics and metals will build at different rates.

–Required print resolution; Fine resolutions mean slower build rates.

–Part density. Fully dense parts can take longer to build than those with filler support.

The Ultimaker desktop 3D printer, gives its depositio rates as: With a 0.25 size nozzle, it is up to 8 mm3/s, a 0.40 nozzle it is  up to 16 mm3/s, a 0.60 nozzle up to 23 mm3/s, and a 0.80 nozzle can deposit up to 24 mm3/s.

Professional 3D printer, the SLM Solutions 500HL gives deposition rates for its two-laser version as 55 cubic centimeters/hour, and its four-laser version as 105 cubic centimeters/hour.


Comparison of FDM, SLA and SLM

Fused Deposition Modeling (FDM)

Fused Deposition Modeling is the most widely used form of 3D printing at the consumer level. ,  FDM 3D printers build parts by melting and extruding thermoplastic filament, which a print nozzle deposits layer by layer in the build area. FDM works with a range of standard thermoplastics, such as ABS, PLA, and their various blends. The technique is well-suited for basic proof-of-concept models, as well as quick and low-cost prototyping of simple parts. .

Stereolithography (SLA)

Stereolithography was the world’s first 3D printing technology, invented in the 1980s, and is one of the most popular technologies for professionals. SLA uses a laser to cure liquid resin into hardened plastic in a process called photopolymerization. SLA parts have the highest resolution and accuracy, the clearest details, and the smoothest surface finish of all plastic 3D printing technologies.  Material manufacturers have created innovative SLA resin formulations with a wide range of optical, mechanical, and thermal properties to match those of standard, engineering, and industrial thermoplastics.

Selective Laser Sintering (SLS)

Selective laser sintering is the most common additive manufacturing technology for industrial applications. SLS 3D printers use a high-powered laser to fuse small particles of polymer powder. The unfused powder supports the part during printing and eliminates the need for dedicated support structures. SLS is ideal for complex geometries, including interior features, undercuts, thin walls, and negative features. Parts produced with SLS printing have excellent mechanical characteristics, with strength resembling that of injection-molded parts.

Nowadays to increase productivity of SLM process, high laser power up to 400 W and high scanning speed up to 3 m/s are used.

Smaller thickness of layer allows for better accuracy of the manufactured part. But increases manufacturing time. (page 122 of the book)
