When designing a 3D model that you will print using a desktop 3D printer, you might want to consider building size limitations. You can get the best result by designing your model so that stress and layer lines are perpendicular to each other. These will be pulled apart from another if they are parallel with any stress. The layer lines are basically the weakest points of the print. If you design a part meant to carry a substantial load, make sure you also consider FDM printing’s strength limitations. Even though you can rotate the models along any axis in the slicer software, don’t forget that these three axes’ resolution is not equal. It’s best to orient the details along the z-axis if you like exact details in the model. This is an important consideration if your 3D character modeling service features wonderful details. However, the nozzle’s size determines the resolution on the y-axis and x-axis. But you can set the thickness of the layers to control resolution along the z-axis. It’s an inherent result of how FDM printers rely on wide nozzles. It’s natural for 3D prints made using FDM technology to be produced with some visible layer lines. Orient according to strength and resolution It also lets a 3D product modeling service preserve your 3D model’s quality even when you distribute it for free on different download sites for 3D models. What makes this approach great is that you don’t need to compromise your design by changing some of the feature’s geometry. You can also plan and make the figure pose so that there are no overhanging features. According to studies on ancient sculptures, the sculptors often used hidden supports so their creations wouldn’t collapse under their own weight.įor example, when you design an action figure, the figure should lean on a pillar or signpost. There is no hard and fast rule on how to do it because it all depends on your creativity. Integrating anchors to your design is among the more creative ways of reducing supports. The droop can increase to as much as 5mm for bridges with a length of over 60mm. The general rule of thumb is that bridges less than 36mm are expected to have a maximum droop of 0.5mm. The severity of the droop depends on the filament’s weight and the bridge’s length. Droop is the sagging of the bridge that is most visible at the middle portion. But you will still surely need a degree of droop here. RELATED: The Benefits of Using 3D Printing Technology for EducationĪ bridge buckling under its weight is the worst thing that can happen. It can differ across various nozzle diameters and filament materials, so make sure you know the limits of both your filament and printer. Be familiar with the concept of droop and bridgesĪ bridge is a horizontal feature with no underneath support, and its terminal ends are connected to the other parts of the model. Going beyond the 45-degree boundary might push the limitations of the filament material’s strength, so it’s best to keep every incline close to just about 30 degrees. This is a wider incline that is split into segments of 45 degrees. A chamfer can also be added if necessary. Inclines that are more than 45 degrees will require a support structure to support their weight. When designing a 3D model, you might want to follow the 45-degree rule. They don’t just use up lots of filament-the removal process might also create uneven surfaces or cause damage to the finished print. But most 3D printing design services only turn to this as their last option. The addition of support structures can quickly solve the issue of overhanging features. When it comes to working with 3D modeling design services for 3D printing, you need to consider several factors to be sure that you can create and print exactly what’s in your mind. Some are more difficult to pull off compared to others. Unfortunately, there are times when 3D models don’t turn into what you envisioned once you start printing them. It only takes a few hours for you to develop your very own 3D model that you can transform into a physical object. The technology provides an exceptional combination of easy reproduction and complete freedom when it comes to design. Thanks to the revolutionary new technology that is 3D printing, it’s now possible for you to bring even your wildest imaginations into reality.
