On the flip side, keep in mind that your product must fit into the machine's tray, so don't make it too big. As a result, it's critical to select the same unit on our platform as you did in your CAD software.Īlso, do not want to reduce the scale of your model a lot since the finest elements may not be able to be 3D printed. A 10x10x10cm cube, for example, will become a 10x10x10mm cube. It should also be noted that when you create a 3D model in centimeters in CAD software, the object's unit of measure will be modified when you upload it and pick millimeters. When you open your CAD program to create a new file or scene, you are typically asked what unit of measure you wish to use for this modeling project. In short, you must know the precise size and dimensions of your model, whether you use the metric system or not. Setting CAD File Unit of MeasureĪs you will be turning a digital model (the CAD file) into a physical object, it is crucial to control the size of what you're printing. The most straightforward technique to determine whether a model is printable is to utilize analyzer software to identify model elements that can create problems during 3D printing. It should also be noted that non-manifold concerns are frequently undetectable during the modeling phase. Inconsistent layers, holes, and other problems may result from a non-manifold 3D model, rendering the item unprintable. This is mainly because the software that creates the instructions for the 3D printer slicer may misread models that are not manifold. This means, each edge should be linked to precisely two polygons, and there should be no holes in the model. Also, every 3D model for 3D printing should be totally manifold (watertight). Thin features cannot be 3D printed unless they are larger than the technology's minimum workable feature size. SLS - up to 750 x 550 x 550 mm Other Factors to ConsiderĪrchitects and game designers frequently create objects in 3D models with limitless thickness (hair, capes, sails, etc.).Material Jetting - up to 1000 x 800 x 500 mm.Binder Jetting - up to 1800 x 1000 x 700 mm.To get a better idea of what you're getting into, here is a quick breakdown of the typical size limitations of common 3D printers: There are 3D printers on the market that can print components that are 50-100 cm (19.5-39 in) in length however, this frequently limits your options to industrial 3D printers. Benchtop big format 3D printing may be used to manufacture full-scale prototypes, models, and production components for a range of industries, including consumer goods, healthcare, manufacturing, and more. Most big 3D printers currently have a sweet spot of roughly 30 cm (11.8 in) in one dimension and around 15-30 cm (5.9-11.8 in) in the other two. But these large sizes are mostly reserved for industrial 3D printers. Print volumes in modern large 3D printers can exceed the 15-20 cm (5.9-7.9 in) cube size prevalent in desktop 3D printers. Also, don't be fooled by what may look like an available build area with the actual build area in a 3D printer. However, it should be noted that a non-equidistant 3D shape is not a cube but rather a convex polyhedron or a cuboid that's been bound by six quadrilateral faces. When a manufacturer provides a maximum print area (also called a build area), it refers to the largest item that the printer can theoretically produce. While printer prices fluctuate for a variety of reasons, one constant is that the greater the build area, the more expensive the printer. The size of the build area is one of the most important considerations when purchasing a 3D printer. Given the high cost of outsourcing big components and prototypes, purchasing a large 3D printer can yield a positive return on investment in as little as a few months.įirst of all, when it comes to what size your 3D printer can print, don't always believe what the manufacturer has to say. Today, three alternative 3D printing technologies are available in a benchtop configuration, with prices ranging from $5,000 to just shy of $20,000. While some may believe big format 3D printers are out of reach – prices used to start about $100,000 only a few years ago – the fact is that today's large-format 3D printing alternatives are considerably more affordable. One of the fastest-growing segments of the 3D printing market is large-format 3D printers. Table of Contents Factors That Influence 3D Printing Sizes
