Two years after Formlabs delivered the first SLS printers, the American manufacturer comes with a more powerful version that is twice as fast as the first generation.The new SLS printer Fuse 1+ 30W is also suitable for new materials, including Nylon 11 CF.As the type designation says, the Fuse 1+ 30W has a 30W laser linked to a scanner with a speed of up to 12.5 meters per second.The first generation of the Fuse 1 has a Ytterbium fiber laser with a power of 10W.The laser spot size of the new generation is also different: 247 microns compared to 200 with the existing Fuse 1 printers.In particular, these two changes drive the increased speed of the new Formlabs SLS printer.Formlabs gives the example of a bicycle saddle, printed in Nylon 12, printed in 201 layers.Here the time gain is 24%.With a shaft coupling consisting of almost 2700 layers, the time saving is 52.2%.This makes the SLS printer even more interesting for machine builders who want to reduce their dependence on supply chains and 3D print more parts in-house, one of the applications among Dutch users of the Formlabs Fuse 1.Formlabs introduces the option of printing with an inert gas to the new generation.Optionally, nitrogen can be added to the building chamber.This ensures that the parts become less brittle and have a higher ductility.The other advantage of using nitrogen is that more powder can be reused after sieving.In combination with the higher packing density of the new printer, the amount of waste is reduced to a minimum.In an example of Nylon 11 (CF), Formlabs says that the use of nitrogen results in 30% new powder being sufficient instead of 50%.Together with the new Fuse 1+ 30W, Formlabs introduces a new material, nylon filled with carbon fibers (Nylon 11 CF).The new agitator in the powder hopper provides a consistent, smooth feed of material into the build chamber, making Nylon 11 CF powder possible.In the future, other materials will also be added to the portfolio.As a result, the content of the hopper is slightly smaller than with the Fuse 1 first generation.Editorial team +31 46 4333 123 Email editorial@3dprintmagazine.eu3D Print magazine uses cookies to gain insight into the reading behavior of visitors.
