![]() Multiple small parts can be designed to connect via tabs to a grid similar to Airfix models, this makes them much easier to clean up and blast. The spread of heat can mean that small details may not show on the surface of parts, if you have features that need to be clear then make them emboss or indent out of the main surface by at least 0.5mm. Be mindful of being able to clear out the dust between the intersecting parts. Print-in-Place parts have some out very well for us so far. ![]() There is a part-fusing of some material around each print for surface-quality-reasons, called onion-skinning.ĭesign parts in such a way as to not trap powder in areas where you can’t reach it, thin channels and right angles in deep enclosed cavities can make powder almost impossible to remove completely. Supports: not necessary, fused powder is supported by unfused powder during printing.ĭistance between prints, can't be 0. This is good reason to use the One-Click Print button to help optimise this. The Packing Density number is an indicator of this efficiency. Print times are majorly influenced by the number of layers (vertical height of the job), but only minor-ly influenced by the amount of printed material on each layer. New materials will be listed on the FormLabs website when available. Other plastics, including TPU (flexible) are in development. ![]() SLS Materials compared on Other materials Compared to Nylon 12 Powder, Nylon 11 Powder is more flexible, less brittle, and better at printing thin walls. Tensile Modulusįor highly ductile, robust parts, Nylon 11 Powder is a higher-performance nylon material for functional prototyping and small batch production. Choose Nylon 12 GF Powder to produce stiff functional prototypes or end-use parts for applications where structural rigidity and thermal stability are critical. Tensile StrengthĪ glass-filled material with enhanced stiffness and thermal stability for demanding industrial environments. Nylon 12 Powder is a highly capable material for both functional prototyping and end-use production of complex assemblies and durable parts with high environmental stability. For the moment we only stock Nylon 12, which is a great all-rounder. Please note, as the Fuse1 is a new machine, both to Fab Lab Limerick and on the in general, Formlabs is still developing other powders that can be used. ©Formlabs, SLS 3D Printing Workflow - The Fuse 1 Demo " Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser as the power and heat source to sinter powdered material (typically nylon or polyamide), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure". 3D Printing - SLS (Selective Laser Sintering)
