Metal and silicone 3D printing is in focus this time with a plan for a new advanced metal additive manufacturing system as well as market readiness of a silicone 3D printer.
SLA pioneer 3D Systems is diving deeper into metal 3D printing, announcing a $15 million contract with the Combat Capabilities Development Command Army Research Laboratory (ARL) as the US Army looks to “create the world’s largest, fastest, most precise metal 3D printer.” The funding goes to both 3D Systems and the National Center for Manufacturing Sciences (NCMS), which are partnering with ARL and the Advanced Manufacturing, Materials, and Processes (AMMP) Program (because it’s not a government contract without an appropriate number of acronyms).
The metal 3D printer is intended to come into play for “key supply chains associated with long-range munitions, next-generation combat vehicles, helicopters, and air and missile defense capabilities.” It will be available to aerospace and defense suppliers that work with the Army, and has speed and scale in mind. The announcement notes that the build envelope is intended to be 1000 x 1000 x 600 mm, with a minimum wall thickness of 100µm and layer thickness of 30µm. No word yet on intended materials nor process, though presumably, it will be a powder bed system to fit into 3D Systems’ existing portfolio – though the company notes as well that they may be expanding “new technologies and processes” here as well.
“The Army will enhance its operational capacity by strengthening relationships and interactions with trading partners, such as 3D systems that meet the demands of the best contributing value fighters,” said Dr. Joseph South, chief of the ARL program. For the next generation of additive manufacturing. Ammunition. “To date, powder coated 3D laser printers are inaccurate enough to allow very small, very slow and large-scale ground combat subsystems. Our goal is to work with allies and partners to solve this problem. The military and the critical National Security Forces Payum contributes to new capabilities for chains.
The latest German wrap-up 3D silicone printer is now on the market. Priced on demand, the L320 3D Printer is part of the company’s Liquid Additive Manufacturing (LAM) series and uses injection molding silicone (LSR).
Using materials already familiar with the industry, complex structures including cross-mesh, lattice and honeycomb geometry can be performed with the LAM system. L320 uses Simplify3D software. Thermal cross-linking with a high temperature halogen lamp reduces printing time compared to other 3D silicone printing offerings. The isolation system uses a touch screen that, in addition to USB, can be connected to a browser control via Ethernet and WLAN; Web camera monitoring can also be done. The L320 offers a 250 x 320 x 150 mm build platform, with a print speed of 10-150 mm/s and layer height of 0.22-0.9mm.
“The L320 3D printer has proven continuous operation reliability through extensive testing and pilot applications. Maintenance contract and professional on-site service is an option for qualified technicians for commercial use, which requires high usability and reliability.” , According to the press release of his investigation.
The company is working on technology development for industrial use and is now launching its new L320 LAM 3D printer. It is a “highly stable” system adapted to the high demand for continuous industrial activity.
LAM technology can affect the direction of the application and can also affect layer-level vulcanization. The polymers used in this process have a better molecular structure since the base materials are used instead of the processed ones. Because prototype 3D models can be switched directly to injection molding, consumers benefit from reduced time spent on the market, and the design freedom provided by 3D printing allows the use of cross, mesh or honeycomb. Filling the pieces. Better optimization of custom products.
With a 250 x 320 x 150 mm build platform and weighing in at approximately 350 kg (without the cartridge system), the L320 features a touchscreen display for intuitive operation, industrial rollers and stand for easy handling, and volumetric extrusion with a lift and sunk system. The printer uses Simplify3D software, and its new printhead technology allows for precise metering and mixing ratios.
“A high-temperature halogen lamp releases activation energy to accelerate complete crosslinking, at the molecular level. This fine-tuned reaction, in both small and large objects, is ensured by the driving speed of the lamp,” German RepRap explains on its website. “Due to this thermal cross-linking, the printing time is considerably reduced, at the same time the printing result, especially also in terms of time savings, sets new standards.”
Through broad testing and pilot applications, the company claims that it has proven the reliability of its new L320 3D printer in achieving precise, continuous operation. The printer also features sound safety technology, which monitors the curing process, and the system also registers and displays any deviations; if there are any serious irregularities, the print job will automatically stop.
New LAM (liquid additive manufacturing) 3D printer from German RepRap called L320 can print with liquid silicone rubber. With a build volume of 250 x 320 x 150 mm, the L320 is significantly larger than their first LAM printer, the L280. ach L320 comes with Simplify 3D, a powerful slicing program that provides maximum control over print parameters. With the L320, German RepRap is providing a solution to the problem that is turnaround time. 3D printing with liquid silicone rubber will provide end-use parts without going through the expensive and time-consuming process of injection molding. From creating custom orthopedic supports and insoles to electronics housing and protective sleeves, there are limitless possibilities for such a 3D printing system.
