Tips before printing and before modeling

3D Modeling Skills zhu

With the wide application of 3D printing, more and more people need to use 3D printing. However, some of you may not know much about it. Today, Prindream has specially arranged for our one of our finest designer who has many years of experience in modeling and repairing drawings to explain some tips before printing and modeling.


First of all, a drawing is required for printing,which should be in the watertight STL format and meet the requirements of wall thickness.

3D Modeling Skills 01

It is recommended to use 3D engineering software for modeling, such as CREo, UG, catia, etc. Of course, you can also use SolidWorks, Rhino, Sketchup and other software for modeling. If there is no water tightness or zero wall thickness due to poor modeling skills, you will need to retouching.

The main content of retouching is to repair the broken surface and wall thickness.

Before printing:


The 3D model and final print ratio should be provided before printing, preferably 1:1.

If there is a hole in the model or the wall thickness is less than 0.3mm, the drawing shall be revised.

Before modeling:


The name of the model and the number of models, as well as the final print size, should be informed before modeling.

If there is a 2D plane drawing, circle the content to be modeled and give the final print size.

If modeling is based on real objects, it is necessary to take pictures of real objects from a full perspective, and indicate the name and number of modeling parts. The pictures taken include front, back, top, bottom and two sides; If the parts need to be taken apart and there is an internal assembly, then pictures of the inside and corresponding hand parts should be taken. The design will give a reasonable quotation based on the picture.

Once you have determined that you need to model, you should also mail the physical object and give the final print size.

If you are modeling without objects, design is needed. Customers need to describe its functionality and appearance.

Designers will design the structure according to the functional requirements, and make the color line according to the appearance effect.

Here’s an example:


If an electric hand board needs to be designed, the scene, temperature and force of the product should be informed before modeling.


First, determine the overall size. The customer needs to provide PCB cad physical screen, internal wiring, horn, battery, etc., so that the design can be stacked according to the internal parts to determine the appearance size.


Second is the interface function, if the need for external equipment, wire and connector need to provide physical.


If it is moving, it should also inform you what kind of movement is required.
