Invisible braces (including transparent aligners and clear retainers) have
the advantages of being aesthetically pleasing, comfortable, easy to maintain,
easy to clean, having a short treatment cycle, and being convenient to put on
and take off. They are quickly becoming the preferred alternative to traditional
wire braces. In short, invisible braces are made by processing plastic sheets
through thermoforming on custom 3D-printed dental models.

1. Intraoral Scanning

Before manufacturing transparent dental aligners, the first step is to obtain
the patient's oral data. Usually, a 3D intraoral scanner is used to scan the
patient's mouth, or a desktop 3D scanner is used to scan physical models or
plaster models to obtain 3D digital model data in STL format.

2. Design

Import the scanned digital model files into appropriate orthodontic or dental
computer-aided design (CAD) software (such as 3Shape, Exocad). The design
software includes two main categories: making transparent aligners and making
clear retainers.

Invisible Aligners

Dentists perform tooth separation, tooth arrangement, animation, and staging
based on the scanned data, communicate with clients to confirm the treatment
plan and schedule, and sometimes use CBCT data for assistance during the
planning stage.

After the treatment plan is finalized, the dental model data for each stage
is output.

Clear Retainers

Retainers are used in the post-treatment phase. To make retainers, only the
scanned dental model data after treatment is needed. Simple operations such as
trimming and filling undercuts are performed in the design software, and
finally, the dental model data is output.

Optional Designs for Dental Model Data

– Hollow Models

To save costs, dental models are usually designed to be hollow, with a wall
thickness generally ensuring no less than 3mm.

– Through Holes

Hollow models have cavities, which may lead to printing failures. It is
recommended to add through holes at the bottom.

– Honeycomb Filling

To reduce the decrease in overall strength of the hollowed model, honeycomb
structures can be used to fill the hollowed areas.

– Reinforcing Crossbars

To avoid shrinkage and deformation of arch-shaped dental models, crossbars
are added at the opening.

– Fixture Positioning

To match automatic invisible brace cutting machines, positioning holes need
to be added at the bottom of the dental model, with specific shapes referring to
the cutting machine.

– QR Codes

Adding QR codes to the dental model, which can be read by industrial cameras,
enables quick and accurate access to relevant information about the dental
model, realizing automatic identification of dental model information.

– Text Markings

Adding concave or convex text markings on the dental model facilitates later
sorting work and greatly improves work efficiency.

3. 3D Printing

(1) Load the model in the slicing software. Thermoformed dental models are
generally printed directly on trays without supports. Then, select the resin and
parameters to complete slicing.

(2) Upload the sliced data to the printer and complete the printing.

4. Post-Processing of Dental Models

(1) Remove the dental model from the tray.

(2) Place the model in a cleaning machine filled with isopropyl alcohol (IPA,
≥96%) for cleaning. To ensure thorough cleaning, it is usually cleaned
twice.

(3) Take the model out of the IPA and air-dry it in a well-ventilated area at
room temperature or dry it with an air gun.

(4) Put the cleaned and dried model into a curing oven and set appropriate
parameters for post-curing.

5. Thermoforming

Using the printed model, process the sheets into invisible braces with dental
thermoforming equipment.

6. Laser Marking

Use laser marking on the sheets for easy classification, packaging, and
traceability.

7. Trimming

– Manual cutting

– Automatic trimming

8. Polishing

Cutting or trimming with scissors or dental handpieces can result in sharp
and rough edges. Use grinders and polishers to trim and polish the edges.

9. Quality Inspection

Quality inspection is a particularly important step in the manufacturing
process. The finished products need to be thoroughly inspected to ensure they
are clean and free of defects.

10. Packaging

Classify according to the client and their treatment cycle, and pack the
invisible braces into custom boxes.

Image sensor

As one of the key components of the camera system, the image sensor can be divided into two types: photoconductive camera tubes and solid-state image sensors. Solid-state image sensors are further divided into charge-coupled device image sensors (CCD) and complementary metal oxide semiconductor image sensors (CMOS). Both image sensors realize their functions by converting optical signals into electrical signals.

In electronic endoscopes, the image sensor is located at the front end of the camera system; in rigid tube endoscopes and optical fiber endoscopes, the image sensor is located at the rear handle. The main comparison between them is as follows:

The two have their own advantages and disadvantages in terms of performance characteristics, cost, etc., and together provide support for endoscope image acquisition.

Optical imaging system

The optical imaging system is a common part of the three major types of endoscopes and an indispensable component of fluorescent electronic endoscopes. It consists of a set of lenses, and the lens material is usually glass or artificial resin. The optical imaging system undertakes the important task of presenting the image to be photographed on CMOS or CCD.

Electronic mirror structure image source network

The main parameters of the optical imaging system include field of view angle, field of view, aperture, resolution and depth of field.

Field of view angle

It refers to the angle between the incident light of the object image and the horizontal line after it first passes through the objective glass and enters the objective lens, that is, the angle of view (DOV, Direction Of View). The endoscope viewing angle is generally 0°, 12°, 30°, 70°, 90°, etc.

The front ends of medical electronic endoscopes and optical fiber endoscopes can be bent, but optical fiber endoscopes are far less tough than metal cables because the optical fiber is easy to break. The maximum bending angle of medical electronic endoscopes is 270°. When the field of view of the optical system is 90°, it can ensure that there is no blind spot in observation.

Field of View (FOV)

Refers to the range that the objective lens can observe, which is called the field of view. The field of view of the endoscope is generally divided into wide angle and standard angle. Different fields of view are suitable for different inspection scenarios, providing doctors with a more comprehensive observation perspective.

Clear Aperture

The size of the clear aperture has an important influence on the depth of field and lighting ability of the optical imaging system. The larger the clear aperture, the stronger the lighting ability of the optical imaging system, the brighter and clearer the image, and the lower the required light source illumination brightness. However, as the clear aperture increases, the depth of field of the system will decrease.

Optical imaging system resolution

The resolution of an optical imaging system refers to the minimum distance at which the "image" of an "object" can be distinguished in detail after passing through the optical system. Two image points greater than this distance can be identified as two points, while two points less than this distance will be identified as one point after passing through the optical system. The optical resolution of an image sensor is expressed by the number of black and white line pairs that can be distinguished per millimeter, that is, there are multiple pairs of pixels per millimeter of width. It should be noted that the image resolution we conventionally understand is the number of pixels used to display the image within a unit distance.

Resolution board type A

For example, the pixels of the micro-image sensor used in smartphone cameras are as high as 20 million or even 40 million, but from the perspective of shooting effects, photography enthusiasts still often shoot with a SLR instead of a mobile phone. The main reason is that the resolution of the lens module of the optical imaging system matched by the mobile phone camera cannot reach the optical resolution of the corresponding image sensor. Therefore, the key to determining the resolution of the entire camera shooting lies in the optical imaging system.

Depth of field

That is, the clear depth of the image of the scene, which is a distance from near to far that the optical system can clearly observe. Within this distance, objects in the scene can form a clear image no matter they are moved closer to the lens or farther away. Reasonable depth of field settings can allow doctors to better observe lesions at different distances during the examination process and improve the accuracy of diagnosis.

DIN 2413 hydraulic seamless pipe seamless is special for high-pressure hydraulic jobs because it is made very well and follows strict rules. Makers use top materials to give the pipe great strength and long life. In hydraulics, every part must work well. These pipes always work the same in hydraulic systems because they meet tough needs, like:

• High strength to handle high hydraulic pressure and heavy loads.

• Exact size for the best fluid flow in hydraulic systems.

• Fights rust and temperature changes, so the pipe lasts longer.

• Seamless build removes weak spots, keeping hydraulic work safe.

Hydraulic seamless pipe seamless always fits what advanced hydraulics need, helping hydraulic systems stay safe and work well in many industries.

Key Takeaways

• DIN 2413 hydraulic seamless pipes do not have weld seams. This makes them stronger and safer for high-pressure hydraulic systems.

• These pipes are made in different steel grades like E235, E355, and 1.4571. Each grade gives strength, durability, or corrosion resistance for different uses.

• The strict DIN 2413 standards make sure pipes have exact sizes and strong materials. This helps hydraulic systems stop leaks and handle hard conditions.

• Seamless pipes fight fatigue and corrosion better than welded pipes. This helps hydraulic machines last longer and work well.

• Industries like automotive, aerospace, farming, and construction use these pipes for important parts. These parts include cylinders, valves, and pumps.

Key Features

Seamless Construction

Seamless hydraulic tubes are special because of how they are made. Makers heat a solid steel billet and push a hole through it. This makes a hollow tube with no weld seam. The tube is smooth and strong all the way through. There are no weak spots or places where stress can build up.

Seamless hydraulic pipes can handle more pressure than welded pipes. They also last longer when used over and over. Welded pipes can have dents at the seam, which lowers their strength. Seamless tubes do not have this problem. That is why seamless steel pipes are best for high-pressure hydraulic work.

Material Grades

How well a hydraulic tube works depends on its material grade. DIN 2413 hydraulic seamless pipe seamless comes in different grades. Each grade has its own strength and hardness. The most common grades are E235, E355, and 1.4571. These grades have different yield strength, tensile strength, elongation, and hardness.

E355 is the strongest and is good for hard jobs. 1.4571 stainless steel does not rust easily and bends well. E235 is easy to work with and has medium strength. These choices help seamless hydraulic tubes work for many different needs.

Fatigue and Corrosion Resistance

Hydraulic systems often face lots of pressure changes and tough conditions. Seamless hydraulic pipes are great at handling these changes. They do not crack or break easily, even after many uses. The seamless design means there are no weak welds, so the pipe stays strong.

Seamless hydraulic tubes also fight rust very well. Using good steel grades like 1.4571 stainless steel keeps the tubes safe from rust and chemicals. Special coatings, like black or oiled finishes, give even more protection. These things help seamless pipes last a long time, even with water, oil, or harsh fluids.

Note: Seamless hydraulic tubes are strong and resist rust, so they are trusted in important jobs like cars, planes, and big machines.

Hydraulic tubes must work well in hard places. Seamless hydraulic tubes do this by using strong materials and careful making. They also have good surface protection. This keeps hydraulic systems safe and working for a long time.

Hydraulic Seamless Pipe Seamless Standards

DIN 2413 Requirements

DIN 2413 has very strict rules for hydraulic tubes. These rules make sure each tube can handle high pressure and hard jobs. Engineers use DIN 2413 to check if tubes are strong enough for their work. The standard talks about wall thickness, material grades, and surface treatments.

Hydraulic tubes must meet certain pressure ratings at different temperatures. For example, a tube with a 4 mm outer diameter and 1.0 mm wall thickness can work at about 707 bar. Its burst pressure is 1755 bar. Pressure ratings change when it gets hot or cold. DIN 2413 gives reduction factors for these changes. Material grades like E355 and E235 help set the right pressure for each tube. Surface treatments like phosphate coating and NBK finish help stop rust and make tubes stronger.
