    • 3D printer researchers at Talos have used 3D printing to bypass fingerprint scanners, and have verified it using Samsung, Apple, and Microsoft mobile devices
    • However, it was very expensive and time-consuming to do- they had to use over 50 molds and it took months to accomplish
    • So the conclusion is that currently, 3D printed fingerprints are not a security threat at scale
    • They remain a fun DIY, 3D printer project, however, and you can check out the video below for a step by step process

    Fingerprinting was first used in 1892 by law enforcement and has traditionally been a dependable ‘biomarker’ of the individual, now mainly supplanted by DNA.

    How to make your own 3D printed fingerprints

    One of the coolest things that you can do with a 3D printer is to print out your own fingerprints.

    This can be done with any type of 3D printer, but it works best with those that have a high resolution. With this method, you can create perfect copies of your fingerprints that can be used for any number of purposes.

    To get started, you will need to have a good quality image of your fingerprint. This can be done by taking a picture of your finger with a digital camera or by using a scanner.

    Once you have an image of your fingerprint, you will need to convert it into a 3D model. There are many software programs that can do this, but the one that we recommend is called 123D Catch.

    Once you have your 3D model of your fingerprint, you can then print it out using a 3D printer. We recommend using a printer that has a high resolution so that the details of your fingerprint are captured accurately. Once your fingerprint is printed, you can then use it for whatever purpose you need it for.

    If you are looking for a fun and unique way to make copies of your fingerprints, then 3D printing is the way to go. With this method, you can create perfect copies of your fingerprints that can be used for any number of purposes.

    However, this has also made it possible for an individual to conceal their true identity from others due to the fact that fingerprints are so easy to replicate.

    What are 3D printed fingerprints?

    What are 3D printed fingerprints?

    3D printed fingerprints is an emerging technology. This device is able to create fingerprints and store them in a 3D file which can then be used for identification purposes. The process has been made easy by advancements in 3D printers and fingerprint scanning devices.

    Fingerprint scanning was once the domain of law enforcement and the criminal justice system. But with 3D printed fingerprints, that could be about to change. The idea is simple: fingerprints are scanned, converted into CAD data (computer-aided design), and then printed for law enforcement use.

    Can 3D printers print fingerprints that can bypass fingerprint security mechanisms?

    Can 3D printers print fingerprints that can bypass fingerprint security mechanisms?

    Yes, 3D printer can be used to scan fingerprints and then print them out as images. A company called Biometrics Fusion has not only developed a way to scan fingerprints, but also a way to print them.

    The latest version of their software is even able to create 3D-printed finger impressions.

    Fingerprint Security Solutions

    Fingerprint Security Solutions

    Right now, no standards exist for 3D-printed finger impressions. However, several security solutions already exist to ensure the protection of data and to prevent bypasses.

    One method for securing fingerprint data is biometric tokenization. This process involves taking a fingerprint and converting it into a digital signature that can be stored in a database or other medium.

    It then uses the token to authenticate users instead of the actual fingerprint itself. This protects the original fingerprint data so that a 3D copy of the fingerprint cannot be used to bypass any security measures.

    Biometric tokenization can be used to secure any type of data, not just fingerprints. For example, some companies store fingerprints on their servers while storing tokens to use with their users’ smartphones or other devices.

    This allows them to allow users access on multiple devices without needing to keep a large amount of fingerprint data stored on each device. It also makes it impossible for an impostor to steal a user’s fingerprint data from a device and use it to gain access to the actual data. This can help prevent data breaches and protect business data


    3D printed fingerprints are close to or exactly the same quality as real fingerprints; they have micro features, pores and other details that are often only found in actual fingerprints.

    • The process is quick and reliable; it only takes a few minutes to scan five fingers and have them 3D printed.
    • The fingerprints created can then be used for many purposes including identification, granting access rights, or even as a form of payment.
    • There are many types of Fingerprint scanners that can both scan fingerprints or use existing systems like passports for identification.
    • The technology used to create 3D printed fingerprints is not invasive, unlike conventional fingerprinting techniques.


    • The method is quite costly; this is more than likely to change as the technology becomes more advanced and less expensive over time.
    • Scanning of fingerprints is often more time consuming than law enforcement would like; it only takes a few minutes to create 3D printed fingerprints for law enforcement to use, but sometimes the fingerprint scanning process can take longer.
    • It is still not clear how effective 3D printed fingerprints might be in an actual law enforcement situation. Although it has been proven that they are almost identical to real fingerprints, there is still no guarantee that they will be accepted as evidence in court.
    • In some cases, the results of 3D printed fingerprints could be affected by the quality of the scanning device.

    Are 3D printed fingerprints Legal?

    Is 3D printed fingerprints Legal?

    No country or jurisdiction in the world currently accepts 3D printed fingerprints as evidence in a court of law. But, this could change in the future.

    3D printers are becoming more common and can be used by anyone with little training. This means that almost anyone who has access to both scanners and printers could potentially be able to create 3D printed fingerprints, which would make them very unreliable in criminal investigations and legal proceedings as there is no way of knowing if they are real or not.

    Despite all these concerns, it is still unlikely that 3D printed fingerprints will be banned; this is because there are positive benefits that could result from their use, including protection of privacy and personal identity.

    Uses of 3D printed fingerprints

    1. Identification

    Using 3D printed fingerprints in the form of a physical print is much more difficult than printing it on paper. This is because there are many types of fingerprint scanners that can be used to identify people by their fingerprint

    2. Access Rights

    Using 3D printed fingerprints in the form of a physical print for granting access rights to buildings, cars and other objects is also possible and can be very useful. But, it is important that the person using this access is sure that they are providing access to the right perso

    3. Payment

    Although this use of 3D printed fingerprints may not be widespread in the near future, it will undoubtedly become more common with time as there are many people who would like to use their fingerprints as a form of payment.

    3D printed fingerprints Issues

    3D printed fingerprints Issues

    1. Technology

    The main drawback with using 3D printers is that they are quite expensive and not easily accessible to everyone. It might be possible in the future for a company like Apple to produce 3D printers that can be used by everyone, but currently, they are only available to those who have a lot of resources.

    2. Scanners

    The biggest problem with using 3D printers to scan fingerprints is the time it takes to create each print. A few people have managed to do this in less than 10 minutes, but this is still not possible for most. Although scanners can be improved and the process made even faster, it could take a very long time before they are able to convert all prints in real time.

    3. Protections

    Although it is not clear how realistic this could be, there are plans to create 3D printed fingerprints that can be used as a form of protection. In the future, people may be able to use a special ID that uses features of their fingerprints to authenticate them.

    4. Law Enforcement

    Because 3D printers are used by anyone with little training, they could easily be abused by criminals who will use them to make fake fingerprints. This may become very common in the future as technology improves.

    5. Privacy and Security

    Some people believe that people should be allowed to keep their fingerprints secret. Although this is not currently possible, it could become a reality in the future as technology improves.


    3D printers are still in their infancy and there are many issues that need to be overcome before they can become a common household thing. This process will not take very long as in a few years, 3D printers will be used by everyone.
