Learn how your throughput may be limited with traditional submersion support removal systems. As additive manufacturing scales to production levels, post-print cycle time and manual labor are a growing concern.
For good reason, Fused Deposition Modeling, or FDM™, is a top print technology choice. From 3D printing enthusiasts to large scale production facilities, FDM adds value as a reliable, versatile, and cost-effective option that can provide near injection-molded surface quality with the right finishing solution. The simplicity of the technology is where many of the benefits of FDM are derived. While there are methods to mitigate labor costs in the additive manufacturing process, one unavoidable cost is material.
In the case of FDM, the material used is a filament. The polymer manufacturing process used to produce these filaments, single screw extrusion, is a proven process that has been around since the 1950’s that offers much flexibility. Additives and pigmentation can be added to the raw resin prior to extrusion for a wide range of practical material options. The extrusion is spun onto a spool, akin to a fishing line, and this is the form in which it is loaded into the FDM printer. The concept behind the print technology is also quite simplistic, relatively speaking. The material is fed through the print head where it is melted to temperatures upwards of 450F and extruded layer by layer, ranging from 0.005” to 0.010”, as the build platform lowers accordingly. Although with the deposition process, one challenge can be complex geometries.
