3D Modeling Software

3D modeling is a key step in the realization of 3D printing technology. Whether in cultural creativity, animation and film, medical industry, construction industry, industrial manufacturing, food industry, etc., if you want to print something, you must perform 3D modeling before you can use it. The 3D printer prints the modeling data. Any 3D design software can be used to design a 3D model. As long as it is modeled with software with suitable 3D printing technology characteristics, it can be exported or converted into STL format software to achieve the best results.

3D modeling software is divided into two main types:

  • One is for artistic creation and design, such as decorative artwork, movie special effects prototypes, animation figures, dolls, cultural creativity;
  • The other is industrial product design. Of course, there is also a 3D modeling software with special value, Rhion, which is not only used for industrial design and mechanical design such as CAD, CAM, but also can create excellent 3D models for cartoon design, movie special effects, and three-dimensional animation production.

Industrial Product Design

Medical 3D Modeling

Traditionally, doctors can obtain CT two-dimensional image information through CT scans. However, for the understanding of CT two-dimensional images, doctors need to abstract into 3D images in their minds with experience to further diagnose and treat liver tumors and other medical diseases. This experience is often Not reliable enough, deviations may occur.

3D printing technology can realize that the data provided by medical institutions can be processed by professional doctors. The image data obtained by the provided X-ray CT machine and MRI MRI scan can be converted into CAD data required by the input 3D printer for 3D printing model. The 3D printing model not only has the same three-dimensional visual function and individualized characteristics as the digital three-dimensional model, but also has the function of manually touching and marking important anatomical structures, which provides a new method for medical teaching, clinical and scientific research.

3D printing technology will have a wider range of medical applications in the construction of medical models, artificial bones, the manufacture of biological organs, teeth, and plastic surgery.

Especially in the mold manufacturing process, it is often necessary to repeatedly try and modify the mold surface. If the mold that meets the requirements is measured and its digital model is reversed, this spare digital model can be used to generate the processing program when the mold is repeatedly manufactured, which can greatly improve mold production efficiency and reduce mold manufacturing costs.

Reverse Engineering

Reverse engineering is a process of obtaining product CAD models from existing physical models (existing products, hand touches, clay sculpture molds, etc.), that is, using various digital technology and CAD technology to re-use 3D software to construct CAD models The process of cloning or creating physical products is characterized by fast, convenient, and intuitive, and is especially suitable for product design with complex geometric shapes and many free-form surfaces. Use the advanced high-precision scanning system to obtain the smallest and most complex features of the geometric model, Obtaining accurate, clean and high-resolution 3D scanning point cloud data is the key to CAD model reconstruction of complex surfaces. Reverse engineering plays a significant role in shortening the development cycle of new products, reducing costs, and improving the ability of independent product development in the manufacturing industry.

  • If your design is more complex, 3D intelligent manufacturing network may be judged as special-shaped parts, and the quotation will be made according to special specifications.

The Requirements Of Document Entity Design

When rendering renderings, you don’t need to consider the thickness, just the appearance, but if you need to print out the real thing, you need to think about this during the modeling process. The created model needs to be all closed solids, not surfaces or one-sided faces with no thickness.

The Requirements Of Document Entity Design

The Design Requirements Of Thread

The pitch refers to the axial distance between the corresponding points of two adjacent teeth on the thread, as shown in the following figure:

The Design Requirements Of Thread

The profile angle refers to the angle between the two sides of the thread profile.

The accuracy of the printer will affect the pitch and profile angle.

Depending on the material selection, your design needs to meet the minimum pitch and minimum profile angle requirements, as follows:

Material8000 photosensitive resinTransparent photosensitive resinHP High Performance Nylon ( Black )Nylon fiber-reinforced ( black )
Pitch0.6mm0.6mm0.5mm0.6mm
Tooth Angle20°20°20°20°

The Requirements Of Deep Hole/Bent Hole Design

The inner diameter of the hole needs to be larger than the minimum hole diameter requirement. The minimum hole diameter requirements for different materials are as follows:

Material8000 Sensitive Resin8100 Tough ResinTransparent Photosensitive ResinNylon ( White)Nylon ( Black )
Minimum Aperture1.2mm1.2mm1.2mm1.5mm1.5mm

The Requirements Of Model Minimum Wall Thickness Design

On the designed 3D digital model, the inner and outer surfaces of the model are closed to form thin walls.The thin wall is divided into supporting thin wall and non-supporting thin wall.

The supporting thin wall connects the structural features of at least two surfaces, as shown in the following figure:

The supporting thin wall connects the structural features of at least two surfaces, as shown in the following figure:

Unsupported Thin Wall: Structural features that connect less than two faces, as shown below:

The supporting thin wall connects the structural features of at least two surfaces, as shown in the following figure:

The wall thickness of the model determines the strength of the product, which also determines whether the model can be printed.

After the model is printed, it needs to go through support removal, grinding, sandblasting, etc. These processes determine the minimum wall thickness of different molding methods.

The minimum wall thickness requirements for different printing methods are as follows:

3D Printing MethodMinimum Wall Thickness Requirements
SLA 3D Printing Services0.6mm
SLS 3D Printing Services0.8mm

The model is printable only when the wall thickness reaches the minimum wall thickness requirement. If there is a thin-walled structure in your model design, we recommend that you design a wall thickness of more than 1mm.

The wall thickness needs to increase with the size of the model. If the wall thickness of the product is insufficient, Be-cu.com’s sales service will communicate with you according to the actual situation and give you suggestions for modification.

Minimum Wall Thickness Design Requirements for Columns

Supported column: In the model, if a protruding structure has a length that is twice or more than its width.

Among them, the structure where both ends are connected to the thin wall, as shown below:

the structure where both ends are connected to the thin wall

Unsupported column: a structure with only one end connected to a thin wall, as shown below:

a structure with only one end connected to a thin wall

Processes such as support removal, grinding, and sandblasting determine the minimum column wall thickness requirements.

The minimum wall thickness requirements of different molding methods are as follows:

3D Printing MethodSupport ColumnUnsupported Column
SLA 3D Printing1.2mm1.5mm
SLS 3D Printing1.0mm1.0mm

The wall thickness of the column needs to be larger than the minimum wall thickness requirement to print. If your design does not meet the minimum wall thickness requirement, it is recommended that you increase the wall thickness.

If the model cannot be printed due to the problem of wall thickness, the official customer service of Be-cu.com will communicate with you according to the actual situation and give you suggestions for modification.

The Requirements Of Concave And Convex Detail Design

The bump detail is the part that is raised or recessed on the model, as shown in the image below.

The Requirements Of Concave And Convex Detail Design

The smallest bump detail is usually determined by the precision of the printer.

The minimum height and width requirements of bump details of different materials are as follows:

3D Printing MethodMinimum Feature
SLA 3D Printing0.3mm width and height (depth)
SLS 3D Printing0.7mm wide and 0.4mm high (deep)

When the depth or width of the bump detail is smaller than the minimum bump detail requirement, it will not be able to print accurately, and it will not be possible to perform post-processing such as sanding and sandblasting.

At this point, we recommend that you increase the depth, width, and remove this part.

If it cannot be printed due to wall thickness problems, Be-cu.com customer service will communicate with you according to the actual situation and give you suggestions for modification.

The Requirements Of Escape Aperture Design

If you are designing a hollow part, you need to design escape holes in appropriate parts to remove unused material in the printed product, as shown below:

The Requirements Of Escape Aperture Design

The design of the escape hole needs to ensure that the hollow part is large enough, and its hole should be greater than 2mm, so that the hollow part diameter can be cleaned.

If the escape holes do not meet the minimum requirements, it is recommended that you increase the size of the existing escape holes, increase the number of escape holes, or fill in the hollow parts.

If it cannot be printed due to the problem of escape aperture, Be-cu sales service will communicate with you according to the actual situation and give you suggestions for modification.

The Requirements Of Minimum Bore Design

When there is a small hole-like structure on the surface of the model, as shown in the figure below

Minimum Bore Design Requirements

The minimum hole diameter requirements for different molding methods are as follows:

3D Printing MethodMinimum Diameter
SLA0.5mm
SLS1.0mm

The designed aperture does not meet the minimum diameter requirement, and the hole may be blocked during the printing process.If you need the exact hole design, make sure each hole meets the minimum hole diameter requirement.

If the model cannot be printed due to the minimum aperture problem, Be-cu sales service will communicate with you according to the actual situation and give you suggestions for modification.

The Requirements Of Minimum Clearance Design

The printing gap refers to the distance between any two parts, thin walls or columns, as shown in the following figure:

When the designed model requires multiple parts to be printed in one piece, the minimum clearance of the SLS 3d printing process is 0.5mm.

If the gap between parts is smaller than this standard, post-processing engineers will not be able to remove the residual powder, resulting in gap failure.

At this time, it is recommended that you increase the gap size or select other materials with small gap requirements.

If the independence of the two parts of the model is not important, it is recommended that you combine the two parts into a whole.

The Requirements Of Minimum Clearance Design

The Assembly Design Requirements Of 3D Printing

When the model needs to design the assembly structure, it is necessary to keep the assembly clearance, which refers to the required assembly tolerance between the two assemblies of the model (for example, the distance between two gears or joints).

Generally, the minimum assembly gap is 0.2mm . If the gap is less than 0.2mm , the error of the parts will cause the two parts to fail to assemble.
