The smallest nozzle that Ultimaker machines use is 0.25 mm diameter. 06 mm and minimum wall thickness should be 0.5 mm. When designing small features, you should consider height, wall thickness, and nozzle size. It’s important to note, however, that with active cooling and other optimization settings, we have printed up to 25mm with Tough PLA on an Ultimaker 3D printer. Follow bridging support guidelinesĪs a general rule for most basic filaments, FFF printing does not need support when bridging materials within a 10mm gap. Overhangs below 45 degrees should be supported from below with support material. Evaluate overhang support requirementsįFF printed parts are self-supporting up to 45 degrees, which is different from other 3D printing technologies that require support material for all angles. This can affect the overall print time, the post-processing time required to remove support material, and the surface finish of certain faces. As seen here, if the tensile test sample is printed flat, it will be stronger in the tensile direction, because the layers would be aligned in that direction.Ī print’s orientation directly affects the location of overhangs – and whether the model will need support. Mechanical properties are anisotropic, which means they differ depending on their direction. Decide orientation earlyīecause FFF prints layer by layer, determining the print orientation early in the process helps drive design choices, text alignment, and snap features. You can create locating features to combine them later. By using a modularized design, you can simultaneously print two parts on different machines. If a part is too big, we recommend you use modularity (printing then combining separate parts). The Ultimaker S5 is 330 x 240 x 300 mm (13 x 9.4 x 11.8 inches), which is large enough for approximately 80% of our customers’ applications while maintaining a high level of accuracy. ![]() Your 3D prints can only be as large as the build volume. When designing for 3D printing, there are best practices to help you get the most value from your 3D printer the parts it creates, improve print success rates, reduce production costs, and boost the speed of your product development cycle. The biggest benefit of injection molding is the fast production of large quantities of parts and providing an end product with a smoother surface finish. Unlike injection molding, FFF 3D printing does not require the creation and maintenance of a mold, and allows for fast and easy design modifications. Injection molding requires a level of expertise typically only with hands-on experience, due to the hundreds of process parameters and design constraints. When evaluating injection molding, FFF 3D printing stands apart due its low barrier of entry - in terms of both cost and knowledge. Additionally, CNC machines may be preferable for certain advanced application requirements that can’t be met with material filaments, such as PLA or ABS. However, this often leads organizations to lean on a supporting fleet of 3D printers to back up the long CNC queue and simultaneously create parts. For batch production, FFF can take longer, as CNC machines are expected to produce parts at a faster rate once the product is finalized and the G-code is produced. FFF 3D printing outshines CNC in three key areas: fast turnaround time for low quantities, shorter manufacturing workflows, and easier production of complex parts. CNC machinesĬomputer numerical control (CNC) machines automatically create tools or parts via coded and programmed instructions. Following the best practices for FFF 3D printing can help ensure a print's quality and success rate When should you use FFF 3D printing?įirst, let’s break down some of FFF 3D printing’s pros and cons – as well as compare it to other forms of manufacturing.
