3D Printing in Blockchain

3D Printing in Blockchain

If blockchain can be used to solve the problem of 3D printing file transmission, it may also create a new 3D printing business model. Next, let’s take a look at how to implement 3D printing on the blockchain.
1.Protect 3D printing files through hashing algorithm.
The encryption algorithm generates a unique hash value fingerprint for each file based on its contents. This is a mark that uses short information to ensure the uniqueness of the file. This mark is related to every byte of the file, and it is difficult to find the reverse pattern.
The blockchain does not store the file itself, but a hash value that verifies its authenticity. No two files will have the same hash unless they are absolutely identical; changing anything about the data will result in different hashes. Through improvements to this technology, 3D printing files are converted into digital artifacts on the blockchain, and the unique fingerprint of each artifact is used to verify its authenticity and uniqueness.
2.Protect access to data through encryption.
After the first step of the method, the encrypted conversion of the 3D printing file has been implemented, and then the access rights are tokenized and bound to the hash value of the file storage. When a 3D printed file is shared, the recipient gets a token that allows access. Without this token the file cannot be decrypted, ensuring authentication before using the 3D printable data.
The biggest benefit of using blockchain for 3D printing is the establishment of trust. Designers no longer have to worry about their designs being used illegally, and only need to focus on improving their skills and making better models; individual users can also choose different ways to print files, either by printing the number of times or by obtaining file access. You have permission to download directly, but now the price will be relatively lower, and the source of the model is transparent.
Manufacturers can also choose to produce locally near customers, which in turn reduces storage and transportation. On-demand production is also beneficial to the environment and achieves carbon neutrality. In addition to selling real goods, brand manufacturers can also sell printable files to customers for replacement parts, customization and accessories. This is all thanks to their IP being protected by the blockchain.
In short, the 3D printing blockchain will promote the use of 3D printing technology to a greater extent, and the blockchain will enable 3D printing to be traded in the form of "tokens". Think about the early days of the use of Bitcoin, and conversely look at the monetization of 3D printing blockchains. Perhaps one day, our machine usage time can also be sold online, and 3D printing files can also be traded in various ways through currency.
