German RepRap Introduces New L320 3D Printer for Liquid Additive Manufacturing

First launched on the AM commerce present circuit in 2017, the distinctive Liquid Additive Manufacturing (LAM) 3D printing course of by industrial 3D printer producer German RepRap works considerably like FDM, as every layer is extruded after which cross-linked by way of thermal curing. This could create components which have very fascinating mechanical properties which may permit for a lot of new functions in 3D printing.

The corporate’s LAM know-how, developed in partnership with Dow Corning, works with supplies that aren’t melted after which solidified once more, as with FFF 3D printing. As a substitute, the method makes use of a liquid materials, like German RepRap’s customizable polyurethane-based plastic, which is then vulcanized underneath warmth publicity; that is what totally cross-links the person deposited layers so they’re firmly linked.

What additionally makes LAM such a singular AM course of is that it permits for the economic 3D printing of liquid or excessive viscosity materials, reminiscent of Liquid Silicone Rubber (LSR). The corporate claims that LAM 3D printing could make parts with practically the identical properties as injection molded components, which may show helpful in creating new buyer teams that want a extra economical methodology of producing. Particularly in versatile supplies, this course of may see many thrilling functions within the medical or footwear enviornment. Silicone has glorious properties and plenty of companies are very conversant in utilizing it.

German RepRap L320

This fall, German RepRap introduced its LAM course of at formnext 2018, together with its first production-ready LAM 3D printer, the L280. The corporate has been working to additional develop the know-how for business use, and is now introducing its new L320 LAM 3D printer, which is an “extraordinarily secure” system, based on German RepRap, that has been “tailored to the excessive calls for of business steady operation.”

With a 250 x 320 x 150 mm construct platform and weighing in at roughly 350 kg (with out the cartridge system), the L320 incorporates a touchscreen show for intuitive operation, industrial rollers and stand for simple dealing with, and volumetric extrusion with a raise and sunk system. The printer makes use of Simplify3D software program, and its new printhead know-how permits for exact metering and mixing ratios. The nozzle itself would appear to be one by German agency Viscotec however this was not disclosed.

Thermal crosslinking

LAM know-how makes it potential to affect the appliance route, in flip influencing layer-level vulcanization as properly. The polymers used on this course of have a greater molecular construction, as base supplies, relatively than processed ones, are used. As a result of insights from 3D printed prototype fashions will be instantly transferred to injection molding, prospects profit from a lowered time-to-market, and the design freedom afforded by 3D printing makes it potential to make use of cross, lattice, or honeycomb buildings to fill components for higher optimization of custom-made merchandise.

“A high-temperature halogen lamp releases activation power to speed up full crosslinking, on the molecular stage. This fine-tuned response, in each small and huge objects, is ensured by the driving pace of the lamp,” German RepRap explains on its web site. “Resulting from this thermal cross-linking, the printing time is significantly lowered, on the similar time the printing outcome, particularly additionally when it comes to time financial savings, units new requirements.”

The printer additionally options sound security know-how, which screens the curing course of, and the system additionally registers and shows any deviations; if there are any critical irregularities, the print job will routinely cease.

To request take a look at prints, or to speak about buying the L320 for particular person use, e-mail [email protected] Industrial customers who require excessive reliability and availability may get a upkeep contract and skilled on-site service from skilled German RepRap technicians. This service consists of and software program coaching, along with upkeep and restore of the L320 itself.
