3: 3D PRINTING FOR EOAT 216-535-4848
Additive Manufacturing by EMI
3D Printing Machining Lead Times Due to the fast and robust nature of the processes lead times are better for 3D printing Precision + While 3D Printing can be precise, machining can hold tighter tolerances Complexity 3D printing has less manufacturing constraints so it can produce more complex parts Strength Machined metal is stiffer and stronger than plastic Thermal Limit Metal can handle higher temperatures Weight Complex internal lattice structure can be utilized in printing to lighten parts Material Waste Very efficient process allows for very little scrap Cost Effectiveness In general 3D printed parts cost less than machined parts *Comparison can differ depending on materials and processes
All manufacturing methods have their own benefits and drawbacks. Additive manufacturing methods have some benefits that traditional machining methods do not.
EMI offers four methods of 3D Printing for EOAT application components: Machined vs. Additive Manufacturing
MJF SLA FFF SLS Description Powder-Based PA-12 (Nylon) is our main method due to its isotropic and mechanical properties. Provides exceptional detail and a wide variety of materials that can be used in many EOAT applications. Nylon based filament with optional fiber inlay reinforcement.
