3D modeling can be really confusing, especially when it is for printing. The solutions for different requirements are never the same. The software used, materials for printing and even printers differ based on the needs.
Designing a perfect model demands you to take care of many factors. More important is being aware of certain things you must not ignore. Let us see three of the most critical among them.
1. Never ignore material guidelines
Printing materials vary a lot in many aspects. They may be strong or delicate, compact or flexible, uneven or smooth and light or heavy etc. So, the design has to be done in such a way that it perfectly suits the nature of the concerned material. Suppose you have to print the design on a ceramic material, there are certain recommendations that have to be considered and best companies offering the related services never ignore this tip. Your choice predetermines the design guidelines to be followed.
2. Never ignore printing technologies
The printing technology best for a specific material may be the worst for another one. When it comes to ABS, professional service providers proceed with Fused Deposition Modeling and in the case of rubberlike materials like Polyamide, they use Selective Laser Sintering. Ideal technology for precious metals is wax casting. Understanding these is vital for appropriate designing.
3. Never ignore software guidelines
This is one of the most crucial tips. Different software programs are used by professional companies availing 3D modeling services. The software you use can seriously influence the perfection of your services. Based on the software, you may have to join shells together, models may have to be made impermeable and application of wall thickness may be needed.
4. Never ignore wall thickness
You will find relevant information on the wall thickness in our guidelines that have been already mentioned. However, you should have a comprehensive idea regarding how to design 3d models for printing, and therefore, it is necessary to stress on this aspect once again. Often, 3D printing models turn out to be unsuitable for printing, due to issues related to the wall thickness. In case the wall thickness is too low, the small parts of the model cannot be printed. They become fragile and easily breaks off. On the other hand, if the wall thickness is too high, it can cause the item to break or crack due to the internal stress. Therefore, while developing 3d print models, you should focus on the wall thickness. You can have a consultation with us in determining the right wall thickness in your model.
5. Never ignore file resolution
It is important to consider the file resolution when you develop the model. The most commonly used format for 3D printing is STL (standard triangle language). Your design gets converted to triangles in a 3D space. In most of the 3D modeling software, you will find the option to export the designs to a file in STL format. Here, you can set the resolution, as required. In case the resolution is too high or low, it may lead to glitches.
STL file with low resolution: In case the export file has a poor quality, you will not be able to get a good print. In low-resolution STL file format for 3d printing, the triangles are big and you will not get a smooth surface. This can lead to a pixelated print.
STL file with a high resolution: If the resolution in your STL file is too high, the file size may turn out to be too big, which might be impossible to handle at times. Besides, the level of details in the file may be too high, that are unsuitable to be printed by the 3D printers. When you upload your model to the website. It is recommended to keep the file size under 100 MB. You can come to us for 3d printing design tips, that can help you in setting the right resolution.
In most of the software for 3D modeling, you need to define the tolerance of the file you are exporting. This is the maximum distance between the STM mesh being exported and the original shape. When you design 3d models for printing, it is recommended to choose a tolerance of 0.01 mm to make the export without any hassle. If you choose a tolerance less than 0.01 mm, the 3D printers will not be able to print the details. If you go for a higher level of tolerance, the triangles will be visible in the print. You need to choose the best 3d modeling applications for artist to accomplish the task seamlessly. Apart from this, we support several other 3D files as well. If you need any sort of support in 3d modeling for 3d printing, feel free to approach us for a consultation.
