3D scanning for 3D printing

3D technologies have long become a mass phenomenon and an integral part of our lives. 3d printing and 3d scanning are in great demand and are available to everyone today. The creation and printing of 3d models has become an indispensable element of production processes.

3d scanning of objects allows you to get a 3d model of especially large, complex in shape or hard-to-reach objects. As a result, you have a highly accurate 3d model in a short time.

This is the process of creating a three-dimensional detailed product by converting a graphic 3d image into a real object. To obtain a three-dimensional model, it is essential selecting the right 3D Scanners.

3D printer

A device that implements 3D printing using various materials, such as plastic, silicone, acrylic, concrete, hydrogel, gypsum, wood fibers, paper, nylon, stone or polymer chips, metal, etc. It is with the help of a professional 3d printer, which has almost unlimited possibilities and high print quality, that the 3d model of the product you need is created!

3D printing technologies are usually built on the layer-by-layer build-up of polymers, but this is not the only way to print on 3d scanner for 3d printer.

3d printing methods

Powder laser sintering

Printing is carried out using a special powder that is supplied to the printer and distributed over the entire printed surface using a rotating shaft. Excess materials remaining in the printing process, the printer removes itself and applies them when applying the next layer. This method provides high printing accuracy, but a non-smooth surface of the finished product, which requires mandatory post-processing.

Stereolithography

The most commonly used 3D printing method, based on the interaction of a laser beam and a photopolymer resin. In those places where the beam and the resin are in contact, the composition solidifies, after which another layer of photopolymer is applied, etc. The printer itself removes the remnants of unused material and uses them in applying the next layer.

Powder Bonding

With this method, water-based adhesive and starch-cellulose powder are supplied to the printer head. The powder is bound with glue, and this is how the contours of the model are formed. The voids of the product are subsequently curled with liquid wax, which gives the object additional strength.

Inkjet modeling

For this type of printing, wax is used as a support material, and completely different compositions can be used as modeling materials. As a rule, such materials have properties and features similar to structural thermoplastics. The printing process is based on the principle of simultaneous application of modeling and supporting materials, as a result, photopolymerization and subsequent mechanical alignment occur. Inkjet modeling is suitable for creating hard and soft product:

• Creation of a prototype of a new product required for presentation to the customer;
• Production of a mechanism part, in the event of a breakdown or loss of a part of any type of device, using a 3d scanner for 3d printing, you can easily recreate the desired part;
• Printing decorative elements;
• Printout of the presentation layout;
• Development of jewelry and bijouterie, etc.
• Printing 3d models is one of our main activities, and we are responsible for the quality results of each project.

The use of a scanner for 3d printing allows you to build a 3D model without using professional graphics programs, significantly speeds up the process and makes it much easier.

Laser 3D scanners build 3D models based on the analysis of a physical object. 3d scanning of objects allows you to recreate the most accurate model with high quality and quickly. However, 3d scanning should be done under the guidance and supervision of a professional engineer. The scan results, which will still have a certain error, are subsequently edited in special graphic programs, i.e. they are finalized at the 3d modeling stage. After that, you can proceed directly to 3D printing.

Any 3D scanner works based on the principle of stereo vision. The scanner, like the human eye, can measure the size of a physical object and the distance to it.

Three-dimensional scanning is carried out in the following ways:

Contact

A 3d scanner that needs to make direct contact with a physical object in order to carry out the scanning process.

Contactless

3d scanning of objects does not require creating direct contact with a physical object, which in turn makes it possible to carry out 3d scanning for hard-to-reach and large-sized objects – jewelry, architectural structures and cultural monuments.

There are two types of non-contact 3D scanner:

• active non-contact 3d scanner – uses a laser beam or light. When the beam is reflected from the surface of an object, the scanner builds a model based on the reflection data.
• passive non-contact 3d scanner – this type of device takes as a basis for building a model an already existing reflection of a physical object, usually sunlight.

Advantages of 3D scanning:

1. High accuracy of the resulting model – 3d scanning of objects allows you to recreate even the smallest and most insignificant details of the object;
2. High speed – 3d scanning is carried out in a matter of minutes;
3. Mobility – the best 3d scanner for 3d printing can be placed at different angles, which helps to carry out the scanning process of especially large sizes without any problems;
4. Easy to use;
5. Do not require the creation of special lighting;
6. Does not harm the physical object.

If your idea seems unattainable to you, then believe me it is not! Modern 3D technologies give manufacturers more opportunities than they are even able to use in practice.
