Metal 3D printing with a plastic binder and metal powder saves money, and leads to high quality parts that can be 3D printed with ease. This brings the simplicity of FDM to metal 3D printing, and the low price of $100,000 reflects that. The Metal X uses ADAM technology somewhat similar to FDM 3D printing, where metal filament is extruded within more standard polymer filaments, before the 3D printed part is heated to remove the plastic while sintering the metal part to strengthen it. Markforged have taken the 3D printing world by storm, now having taken over $130M in investment to bring to market a wide variety of FDM 3D printers as well as metal printers. Post-processing will take some time, like all metal 3D printers. Their latest entry-level metal 3D printer, the Innovent+, is still very accurate, with a layer height of up to 30 microns, and versatile – able to print a wide variety of MIM (metal injection molding) powders as well as ceramic and composite powders.ĭespite the smaller size, the Innovent+ boasts a number of key selling points, including improved powder flow due to the improved ultrasonic dispensing technology, with spreading and compacting systems to improve the final metal part’s density, as well as more control over the 3D printer’s speed. Rather than for large metal part printing, the Innovent+ is more focused on testing, teaching, and smaller-scale metal 3D printing, such as within universities and laboratories.ĮxOne are one of the main binder jetting 3D printer manufacturers, having achieved great success and become one of the only 3D printer shares on the stock markets (market cap around $200M as of late 2020). Metal 3D printer technology: Binder JettingĬompared to ExOne’s other large 3D printers for more industrial uses, the Innovent+ is a smaller and more compact machine with a smaller build volume for different applications.Part 1: Metal 3D printers for smaller scale production ExOne Innovent+ - Entry-level low cost metal 3D printer We have separated our metal 3D printer buyer’s guide into two parts, with part 1 concerning metal printers for smaller scale production, such as in universities and laboratories, and with part 2 concerning larger scale metal 3D printers for industrial metal printing. These parts can be printed as one part on a metal 3D printer, leading to stronger parts. New design possibilities: metal 3D printers can create parts with geometries that cannot be created using traditional methods, or that previously needed to multiple parts.Additionally, parts do not need to be printed solidly – they are strong even at 20% infill – meaning a large cost saving from using less material, and parts can be far lighter a huge advantage in industries such as automotive and aerospace where saving even a kilogram can save millions. Cost savings: as 3D printing is additive rather than subtractive, only the required material is used, with no wasted metal material left over to increase costs. Prototypes and designs can be quickly 3D printed, tested, and modified and re-printed in record time with metal 3D printers. Quicker production: the improved rapid prototyping capabilities allow companies to go from design to final production stage in record time.
