There are several reasons to choose 3D printing over traditional manufacturing methods.<\/p>\n
- \n
- It gives you absolutely new design freedom. You can reach a level of complexity that was not possible before.<\/li>\n
- The 3D printed parts can be edited on the inside, giving you lightweight but durable structures.<\/li>\n
- 3D printing also operates on layers and the thickness, serving you parts that are stronger, have better mechanical properties or more subtle and decorative characteristics.<\/li>\n<\/ul>\n
Our top 5 Tips for 3D printing small objects<\/strong><\/h1>\n
The keys for successful 3D printing small objects are simple: make every step correct and obey the rules.<\/p>\n
In this chapter, we will go over our best tips and tricks to achieve the perfect 3D print. Starting with the correct STL files preparation, we will move on to the accuracy of your 3D models, then we will go over design guidelines and finally, we will talk about the layer height. We will also advise you on the best 3D printing technology for each type of material. Let\u2019s get started!<\/p>\n
Prepare with correct STL files<\/h3>\n
First of all, you need to make sure your 3D model is precise. You can\u2019t have polygons, walls or faces missing as that will create a hole in your 3D model, or else it will not be printable.<\/p>\n
The 3D model has to be realistic. After all, the 3D designs on your computer will become an actual object and it has to meet all the requirements under other technologies.<\/p>\n
Your part has to actually be functional. In this case, 3D printing is no different from CNC or traditional foundry.<\/p>\n
Remember to always check the design guidelines to assure your 3D models are well prepared for printing. It is crucial for the guidelines to be respected in order for the 3D prints to be accurate and precise.<\/p>\n
Respecting the guidelines<\/strong><\/h3>\n
Here are some essential things to keep in mind. They will help you to achieve the best results.<\/p>\n
- \n
- Minimum wall thickness: It assures your model unbreakable, has minimum detail and clearance. Also to make sure your object will be as accurate as the 3D design on your computer.<\/li>\n
- Maximum\/ Minimum size: It is also worth mentioning. It depends on the size of the bed of the 3D printer and, depending on the 3D printing method, either the sintering laser beam or the nozzle size.<\/li>\n<\/ul>\n
Think about the supports<\/strong><\/h3>\n
Our aim is to print a small object as accurately as possible. Some parts of it might be thin and will require supports, but the supports should be removed in post-processing.<\/p>\n
The models may not be thick enough either for you to gently take out the supporting system. If your 3D design is too thin, it will simply break during the support removal.<\/p>\n
Accurate print: the layer thickness<\/strong><\/h3>\n
Thickness can also be called layer height. Each 3D printing technology has a particular limit of layers, the 3D models might not meet your expectations as the layers of material will be visible.<\/p>\n
Plastic and Resin 3D printing<\/strong><\/p>\n
As mentioned above, each additive manufacturing method has certain characteristics.<\/p>\n
- \n
- PolyJet technology will provide you with some pretty impressive results at 28\u00b5m layer height with resin.<\/li>\n
- SLS technology can make stronger parts with nylon, which still gives amazing results with the high definition option at 60\u00b5m and some very good finishes.<\/li>\n
- MultiJet Fusion can provide with a layer thickness of 80\u00b5m with PA-12. The minimum wall thickness is 0.6mm, compared to 0.8mm of nylon.<\/li>\n<\/ul>\n
Remember to make sure that your 3D models have the right thickness for the exact technology for us to be able to print them.<\/p>\n

<\/p>\nMetal 3D printing<\/strong><\/p>\n
As for Metal 3D printing, we offer 4 3D technologies: SLM, DMLS, Binder Jetting, and Casting.<\/p>\n
The technologies differ in print time, temperatures of binding the metal, and the time to cool your 3D design.<\/p>\n
We also recommend you Casting for the small object. With a layer thickness of 25 \u00b5m, the object comes out precise and accurate, especially for little parts.<\/p>\n
Make the right choice of metal to print objects perfectly.<\/p>\n
