In today’s 3D printing briefs, we start with three new great 3D printers, before moving on to new materials. Finally, we will end with the serial 3D printing of manhole covers. Read on for all the details!
Prusa Research presents an XL large format printer
Czech company Prusa Research released the Prusa Mini in 2019, which is smaller than its popular Prusa Mk3, and has now unveiled the Prusa XL large format, which is the company’s largest 3D printer to date. With a build volume of 14.17 x 14.17 x 14.17″, the new Prusa XL is twice the size of the Mk3 and differs from the company’s smaller systems in that it’s based on the CoreXY system, where a gantry moves the printhead on the X and Y axes and the build plate descends on the Z axis; this provides more stability when making tall prints. The XL also has a modular heating system, which keeps everything even and reduces warping by heating the smaller cells on the print bed only when needed, which is often a major problem with printers large format.
The Prusa XL features a new extruder system, called Nextruder, which the company says will provide automated bed leveling without live Z-adjustment, thanks to a 20:1 gear ratio that precisely feeds filament at through a heating block. Additionally, the printer has an optional upgrade that allows up to five independent toolheads not only for different filament colors, but also for different material types and printing temperatures. New Prusa XL is available for pre-order for a $199 refundable deposit, and shipping is expected to begin in the second or third quarter of 2022.
Anisoprint presents the largest industrial 3D printer
Luxembourg company Anisoprint also unveiled its the largest industrial 3D printer to date: the EAST PROM 500, with a build volume of 600 x 420 x 300 mm and adjustable build volumes and flexible fiber paths to allow the use of both continuous fiber reinforced composites and high temperature polymers. The printer meets industry standards for tolerance, safety and reliability thanks to the Bosch Rexroth MTX CNC system and comes with a software ecosystem including Aura and Composer. The new PROM IS 500 has a tool changer for up to four printheads with CCF and FFF extruders, and its database will be continuously updated with new materials and verified profiles.
The printer will launch with ten beta users and testing is expected to take approximately six months. PROM IS 500 beta testers will need to work closely with Anisoprint engineers, so a location in Europe is preferred, and they should come up with a valid industrial use case that can be shared publicly. Additionally, potential beta testers should offer diversity in their business (small, medium, and large), applications, industries, and markets. Any feedback provided will allow Anisoprint to resolve any issues, incorporate features needed for a working machine, and improve reliability. Visit the Anisoprint website if interested.
Expansion of the Moldjet Tritone line with DIM Metal 3D printer
Based in Israel Tritone Technologies expands its product range with the new mid-range Tritone DIM metal printerwhich is powered by the company’s patent pending casting jet Technology. In this process, a mold is produced as a negative of the component, using inkjet-type printheads, from a wax-like polymer. The printed layer is filled in a slot die process with a water-based metallic powder paste, and this process builds the part up layer by layer, allowing for undercuts and unsupported internal channels, before the mold surrounding is removed, leaving the 3D green part for heat treatment and sintering. The new DIM system has a build volume of 220 x 120 x 90mm across four trays, and is intended for use by R&D and educational departments, manufacturers of consumer goods and consumer electronics, and offices of service to create end-use metal parts.
“Our proprietary technology is a game-changer in the AM industry. Tritone’s solution can facilitate any shape, design and complexity for fast-to-market industrial production,” said Omer Sagi, VP of Products and business development at Tritone.” After the initial success of our Dominant system, we are proud to expand our market reach with the DIM system. The market is ready to move from prototyping to producing high quality metal parts.” , and we are proud to be at the forefront of this emerging revolution.
EOS and Metalpine develop sustainable metal powder solutions
Passing 3D printers, EOS acquired a minority stake in the Austrian company Metalpinea subsidiary of the htm invest group, and together the two plan to jointly develop durable metal powders for industrial 3D printing. Both companies are highly motivated to make 3D printing powders more durable, as well as to provide more AM application possibilities for their customers. Metalpine’s atomization technology has been specifically designed for industrial 3D printing, and combined with EOS’ process, materials and systems development expertise, both companies should be able to produce new types of durable powder with maximum efficiency in both material production and 3D printing. process, without wasting resources.
“Metalpine’s technology and team excited us from the first moment. We can now offer our customers even more powerful and sustainable solutions in the interaction between our industrial 3D printing process and the production of metal powder used for this purpose,” said Sascha Rudolph, Senior Vice President EOS Metal Materials. at EOS.
“The Metalpine process allows for a whole new dimension of flexibility and is consistently geared towards the application area of 3D printing. The systems are particularly compact, can be quickly configured for new materials and are so low-emission that they can also be used without hesitation in metropolitan areas. We see a lot of potential for joint development and look forward to working with a highly motivated and professional team. »
4D Biomaterials and Rapid Shape Assessment Bioresorbable Materials
University of Birmingham spin-out 4D biomaterials developed its 4Degra material to help improve patient recovery and care after major medical procedures, and has partnered with fast form to evaluate and print, using Rapid Shape’s vat-curing technology, the first prototype medical devices using its new resin-based bioresorbable inks. 4Degra resin inks, based on polycarbonate urethane chemistry, can be printed using DLP technology to make detailed medical devices that can be implanted into the human body and support its natural healing processes, before to break down into harmless by-products that the body absorbs and then eliminates. through its normal metabolic processes. The chemistry of these devices can be fine-tuned so that they have a range of mechanical properties, and with Rapid Shape’s force feedback technology, they can be printed at high speed. Both companies are reporting encouraging results so far.
“Rapid Shape’s machines are fully compatible with our 4Degra resin-based inks and we look forward to working with them and medical device suppliers to usher in a new era of innovation in 3D printed absorbable medical devices,” said said Philip Smith, CEO of 4D Biomaterials. .
3D Printing Pipelife Custom Manhole Covers
Finally, a company called Lifetime is supposed to be the first to use automated 3D printing and software to fabricate custom manhole covers and inspection chamber flow profiles, and after more than a year of work, will deploy the technology across its group, improving the accuracy and efficiency of polypropylene flow profiles and delivering better product quality, safety and availability. The 3D printer in the company’s Dutch factory has additional automated functions, allowing flow profiles to be produced sequentially without any human interference, and thanks to its increased production speed, Pipelife can deliver more customer orders. , which can be adapted to project specifications. Using connected software, Pipelife can significantly reduce the risk of blockages and stagnant storm water or sewage through optimized hydraulics, and in the case of non-standard connections that are required for water chambers. inspection and looks, the use of automated 3D printing rather than manual production ensures safety. also for workers.
“Usually you would need to manually cut non-standard connections, which carries the risk of accidents. However, thanks to automated 3D printing technology, we reduce or even eliminate injuries,” said Ton Schoenmaker, manager international project in the R&D department of Pipelife.
