In September 2021, the leading developer of dental digital equipment Shining 3D announced a new model of the Aoralscan 3 intraoral scanner. The manufacturer continues the Aoralscan series as the best, according to the creators, scanner for dentistry.

Shining 3D regularly conducts its research and optimizes its dental equipment. The new Aoralscan 3 delivers fast and accurate patient data, and its intelligent data processing capabilities make scanning easy for novices and professionals alike.

Aoralscan 3 can be used for a wide variety of clinical indications. The main application of the 3D scanner is orthodontic treatment, but the equipment can also facilitate diagnosis and determine the treatment plan for dental restoration and surgical interventions.

Functions of Aoralscan 3:

• Texture scan
• The new model can scan in color. This allows to determine the condition of the teeth, see the work of other specialists and more accurately plan the treatment.

Ease of operation

Aoralscan 3 is operated with just one button. The manufacturer has reduced the need for computer contacts, so scanning has become as safe and efficient as possible.

The control PC and the scanner itself can be placed on a special cart. The trolley combines a compact storage space for a 3D scanner and a comfortable workplace where everything is at hand.

New algorithms

Optimized algorithms and imaging engines have improved scanning accuracy by 30% compared to other models. AI scanning maximizes scanning efficiency – the system automatically detects unwanted areas (soft tissue), which reduces the time for a complete scan.

Compact

• The Aoralscan 3 weighs only 240 g for fatigue-free working.
• The removable tip system is reduced in size for more comfortable patient handling.
• 2 autoclavable tip sizes allow for oral scans of small and adult patients.

Software

Shining 3D is a pioneer in dental hardware and software development. The manufacturer offers its software with wide functionality, which can also export data to Exocad.

Scanning

Before starting the scan, users need to install the software and enter a license key. To work, you need a PC to which the scanner will be connected.

Calibration

Scanner calibration is not required, so the user can start scanning immediately.

Controlling the scanner

Shining 3D has tried to make the scanning process as simple as possible. Aoralscan 3 is controlled by just one button, and all manipulations can be performed without constant access to a PC. For convenience, there is a real-time tracking function that helps you see unscanned areas.

Aoralscan 3 has a fairly large scanning area of ​​16x12x22 mm with an attachment for adult patients and 12x9x22 mm with an attachment for small patients.

The large scanning depth allows the use of the equipment in the treatment of periodontitis, as it captures the gum area and allows you to assess the depth of tissue damage.

Scanning tips are 15% thinner and longer than the predecessor model, and also feature automatic anti-fogging for superior scanning results. Replaceable tips can be autoclaved up to 100 cycles.

The speed of the Aoralscan 3 has also increased. A full scan of one jaw takes only 25 seconds, and a full arch takes 1 minute.

Without a doubt, the new Aoralscan 3 is a handy digital dentistry tool. An easy-to-use 3D scanner with intelligent functions allows getting high-quality results in a short time.

Most 3D printers cannot 3D print large life-size model objects in one step. The same problem applies to objects that you want to scale up yourself. Products that are too large simply do not fit inside a standard 3D printer camera.

How you can do it?

The most obvious way for those who often print large objects is to buy a high-tech 3D printer with a maximum build area. CreatBot D600 Pro is a good example. With a 600x600x600mm print volume, heated bed, and high nozzle temperature, it prints large items with the best quality possible.

For those who are not yet considering purchasing such a device, the methods described below will help to get full-size products regardless of the volume of the device’s camera.

3D printing of large objects

If you’re making the most of your axes, know that large-scale projects are easy to accomplish with a standard desktop 3D printer. For this, there are functions for splitting and slicing 3D models. You can edit objects directly in your 3D modeling software.

Search on the Internet

First of all, try to search for the already divided model in the public domain. Many architects, engineers, and designers upload “sliced” versions online because they know that not all 3D printers are designed to print large items. As a rule, the models divided into parts are an archive of several SLT files. Each can easily fit into a medium-sized cell. Searching the internet is a good way to save time 3D printing large objects.

Splitting multipart SLT files

There is a program like Slic3r that converts a 3D model to G-code and generates detailed instructions for the printer. If the model consists of several simple elements, the application will allow you to work with each of them separately. All parts and layers of the object are configured in a special menu. The user can remove sharp corners, remove or add elements, resize them and even combine several projects into one by placing objects side by side on the board or overlapping them.

Another tool for splitting multicomponent STL files is Autodesk Meshmixer. Here, for convenient work with the STL file, you just need to use the “Split shells” command.

3D Printing Large Objects: Splitting Mesh Along Planes

This feature is available in many CAD systems. For this, the Autodesk Meshmixer program mentioned above is suitable. Import the STL file and click the Edit button. It will allow you to adjust the cutting plane by moving the arrows along the axes. You can also create the plane from which you want to cut the model by drawing the intended cut line.

As for the Slic3r tool, here the cut option only works parallel to the XY plane. However, there is another program – Windows 3D Builder. Click on the “Edit” button and select the split option to see the cut plane. You can rotate the cutting plane at any angle along the three axes and move to the desired position. Besides, precise cutting is possible. The rotation and movement tools can be adjusted in degrees and millimeters, respectively.

Additional tips for bonding elements

Making the above manipulations, make sure that the seams will not be too noticeable when you assemble the product in parts. Use high-quality glue to combine the elements into one structure, because the strength of the object depends on this. Remember that most CAD systems allow you to make adjustments to the design concept. For example, you can make several 2mm holes in pre-selected locations and then insert filaments into them. This will help ease the assembly of the product if you are making any props or functional parts. You can also use metal rods, screws, or bolts for a strong bond.

When you take the model apart, print it, and reassemble it, it is important to pay sufficient attention to the processing of the product. It must be carefully sanded to remove any glue residue that may remain at the joints. Also, grinding can smooth out small misalignments between parts.

If there are gaps between the glued parts, you can use the 3D pen and remove the defects using the melted thread. If you want to paint the model, use putty, various fillers, and other materials.

Technology is no longer a separate industry. What remains the same on the surface is revolutionizing inside: processes, approaches are changing and the importance of data is growing. One example is interior design.

Today, this niche is changing under the influence of 3D scanning, preparing for the era of 3D printing, and following the trend of responsible consumption.

What is changing in interior design

It’s not about style. It is not so important what to design – loft or art deco: in the XXI century, you need to rely on technology. Interior design, which has existed in various forms for millennia, is now keeping pace with the information age. And that’s what it means.

Today’s house, first of all, is smart. When designing the interior, you need to create a huge and harmonious mechanism, the number of active parts of which depends only on the wishes of the owner. You can robotize and connect to the hub almost everything: lighting, security systems, automatic shutters, numerous home robots.

The house must be managed from any point, and this requires planning. At the same time, the more manufacturability grows, the more important modularity becomes. Indispensable elements cannot be designed: what can be improved must be easily replaced.

For example, the architectural firm DUS has been designing commercial and residential spaces using 3D printing for several years. According to its experts, this is an ideal way to achieve unique visual solutions without complicating production. And the more affordable the equipment becomes, the better the chances of the technology becoming mass.

Today, people are concerned about what their home is made of and how it has affected the environment. This is evidenced by both the customers themselves and the net data: a study of the visual social network Pinterest, which has 320 million active users, shows a steady increase in interest in the issue of responsible design. The same theme is in the headlines of the best architectural curricula in the United States.

However, changes are usually seen not only by end-users. Interior design is changing from the inside – technology increases the accuracy and convenience for designers. The main engine of progress is 3D-scanning, which allows you to get the most complete and reliable data for processing.

What is 3D scanning and how it works

3D scanning – collection of spatial data. The procedure is performed using a laser scanner that performs millions of measurements. The device analyzes how the light of a certain frequency is reflected from the surrounding space and fix this.

The speed of light is a constant value. Therefore, the distance to the objects is calculated based on the time during which the light beam is reflected in the opposite direction. This emitter is called a LIDAR, it can be found in unmanned vehicles.

Modern construction scanners are accurate and productive, but the cost of professional equipment starts from $50- $60 thousand. Working with the device, the operator moves it indoors and receives the most complete set of data. The duration of the process depends on the area of ​​the object. After completing the fieldwork, the final data are compiled using software (Autodesk, Bentley, AVEVA, Intergraph, Faro Scene) and create a realistic 3D model of the object.

Why laser scanning is important for interior design

Laser scanning is the most reliable way to measure the surrounding space. Measurements are as accurate as possible, the error does not exceed 1 mm.

Such complete and reliable data facilitate the work of an interior designer, especially when working in rooms with complex geometry. Author’s projects of apartments, bars, restaurants, coworking spaces, and offices – in the list of commercial and residential real estate. For example, designers can see the original problems of the object: height differences, irregularities, and other structural changes.

At the same time, the initial measurements always remain in the hands of the customer. The digital fingerprint of the object is securely fixed and allows you to get rid of clarifications and additional checks.

This practice has already become the norm in Europe and the United States – local companies are scanning both large facilities and individual apartments.

The post Technologies Of The Future In Interior Design: From 3D Printing To Laser Scanning appeared first on 3D Scanning Services.

Technology has already revolutionized the way we communicate, relax and work. This process is called digital transformation and all industries have undergone it. One of these is the construction industry.

Of course, architects and designers have long been using advanced software instead of drawing boards, but this is only one side of the coin. Today they have another powerful tool in their hands — 3D scanning systems that digitize the surrounding space to the nearest millimeter.

What is 3D scanning and how does it work?

In simple terms, this is a modern technology for collecting spatial data. The procedure is carried out using a 3D laser scanner, which makes up to 1 million measurements with an accuracy of 0.2-0.5 mm. The device analyzes how the light of a certain frequency is reflected from the surrounding space and fixes it. 

Building scanners are much more accurate and more efficient than emitters in smartphones. Their cost starts from $ 50,000 — $ 60,000. With manual use, the device operator rearranges it from place to place to get the most complete data set. The duration of the process depends on the area of ​​the object and can be measured both days and weeks. 

Why is it important?

This information is of exceptional value to designers and architects. For example, when it comes to modernization or reconstruction of objects, 3D-scanning allows you to minimize the number of errors and miscalculations. While drawings can show the perfect picture, this method evaluates everything realistically.

Creating a “digital double” of a building is important not only in terms of calculations and evaluation. In today’s construction industry, this information is useful to everyone. For example, an insurance company may take into account a model for studying and assessing risks. Rescue services, supervisory authorities can also request a model. According to Kevin Dowling, founder of the Kaarta 3D startup, in the future, even firefighters will first get to know the “digital double” of the building in order to avoid undue risk.

How technology helps preserve the architecture

In April 2019, the world watched with alarm over television from Paris — the Notre Dame Cathedral was burnt. The building, whose age exceeds 800 years, almost collapsed. Notre Dame de Paris collapsed spire, ancient ceilings could not withstand fire and load.

Fortunately, the supporting structures have withstood and now the cathedral is closed for restoration. It will be restored in full accordance with its previous appearance, although it will take hundreds of millions of euros. But experts will rely not on ancient drawings or photographs, but on a detailed 3D model. It was created by architectural historian Andrew Tallon in 2010. For 5 days, Tallon and his colleagues collected data on the building using scanners: more than 50 measurement points and a huge “point cloud” have accumulated. Following it, a detailed 3D plan of the cathedral was created.

Such data is the best help for restorers, explains Raymond Pepi, head of the American Association for the Preservation of Architecture: “Having scans is incredibly important. The building is imprinted in all its flaws and inaccuracies. When you create a drawing, you involuntarily distort everything in the right direction. This helps to navigate, but this is not reality. “

The construction industry is one of the oldest. But no matter how the available tools and materials change, the basis is always the accuracy and reliability. Once the correctness of measurements was provided by rulers and tape measures. Today, specialists have millions of laser beams and 3D models in their hands. Such tools cannot be ignored.
