Manufacturing of any objects made of wood on CNC machines is impossible without knowledge of the theoretical part. Translation of pencil sketches, photos and wishes of customers into numerical language, understandable to the program control of the machine - makes a specialist with appropriate education and certain skills.
Creators of 3d models work in different graphics programs, know how to translate the model into stl format and prepare the layout for cutting, and most importantly - have a good spatial thinking. The result of their work is a file ready to be loaded into CNC for further milling.
Today we will tell you more about creating 3D models. What does this process include, how does it happen, what stages it involves, knowledge of what programs and possession of what skills requires?
Are you interested? Then read! If you just need a finished result, without knowledge of its theoretical part, then go to the main page of the site and choose the desired model from our extensive catalog. Or look in the section "Making models to order", where you can leave a request for the development of stl file on your sketch and request its cost.
What gives 3d modeling?
Let's start with the fact that 3d file performs the most important function - it sets the cutting program for the machine.
In addition, we can say that it is modeling provides:
- Accuracy of shapes and compliance with dimensions: at the stage of development, you can set the desired dimensions with an accuracy of up to a millimeter.
- Visibility: in the process a visual model is created, on the screen you can see how the product will look like, examine it from all sides, approve or finalize any details before the CNC device starts milling.
- Serialization: one model can be used to produce as many products as needed.
- Speed: a quality 3d model, brought to perfection, will only require the carver to select the appropriate material and put the product into production. Milling on the machine on the 3d model is much faster than when the master carves the product from wood by hand.
Stages of creating a CNC model:
- A sketch made in pencil on paper. It should not be a sketch, but a clear drawing with the drawing of shadows. This makes it easier to analyze the shape of the future product: sculpture, frame or pattern.
- Transfer of the sketch into two-dimensional space using vectors. Each detail is drawn manually. If a pattern is created for through-cutting on a CNC machine, this step is enough. For example, files of individual parts for assembly or independent items made of chipboard or plywood.
- Three-dimensional layouts are needed to make three-dimensional elements: wooden decor, sculptures, complex textures. Ready vector file is opened in a program for 3d modeling, and the engineer sets the model volume.
- The model is carefully checked for defects: inaccuracies in size, shape, violation of symmetry and height difference. The file is then saved in stl format. This is not just a file, but a program, a set of commands, executing which the machine will turn out of wood 3d product.
- In some cases is used and "running-in" virtual prototype on the machine: a trial product is usually made on a plastic blank, as it is cheaper than wood. The defects found in the product are corrected in the virtual model. But with our 3D models - this stage you can safely skip. We guarantee high quality files and full compliance of the finished product to the depicted layout.
Programs in the arsenal of 3d engineer:
For the creation of vector files and solid modeling are used most often:
- Autodesk 3DS Max;
- SolidEdge;
- Corel Draw;
- AutoCAD;
- PowerShape;
- T-Flex CAD
etc.
How to assess the quality of a 3D stl file?
Prototyping (creation of 3D models) is a responsible and creative process. The modeler himself can easily understand the quality of his work by the visual layout on the screen: how much the project corresponds to the original idea. The customer can recognize a quality 3D model by such parameters:
- Elaboration of details: a good project even in the form of a visual mockup does not cause questions and censures. The worse the quality of the prototype, the rougher it looks on the screen.
- Exclusivity: even if the mockup was made on the basis of photos-examples, it should, first of all, fulfill the tasks set by the customer.
- The price of the finished file: quality rendered 3d model always has a high price. So that the owner of the CNC machine can simply load the file into the software control and produce the required number of parts, the modeler spends many hours on solid modeling. He perfects complex elements, ensuring that the future product is of decent quality.
- Appearance: there are certain requirements for the decoration (symmetry of the pattern, the correct distance between the parts - preventing the splintering of the decoration, as well as an attractive appearance, compliance with the style, the designer's idea, etc.).
3d models created by STL24 engineers are easily loaded into the software control, edited for the required parameters (length, width), and the output is a high-quality result.
How to order?
- You can choose any project from our catalog. After payment we will send you a file ready to work.
- If you need exclusive modeling based on sketches or photos, send them to our manager. You will need the dimensions of the product, as well as a detailed description of the project. Managers will help with drawing up technical specifications for modelers. The finished project will be delivered within the terms specified in the contract.
Fast, profitable and high quality - this is about us! Leave requests on the site or write to us by e-mail, messengers (watsap, vyber, telegram).
