Abstract: Methods and systems for managing and/or processing a blockchain to maintain data security for confidential and/or personal data are provided. According to certain aspects, the disclosed data security techniques may enable access sharing functionality utilizing the blockchain. For example, access sharing may be utilized to file documents, share policy information, and/or comply with an audit. The data security techniques disclosed herein also enable the use of smart contracts to transfer funds associated with payment obligations and/or other forms of blockchain based payments, comply with anti-money laundering requirements, report industry data, validate interest payments and/or maintain agent sales data. Data security may be achieved through the use of public key/private key encryption techniques.

Abstract: Methods and systems for managing and/or processing a blockchain to maintain data security for confidential and/or personal data are provided. According to certain aspects, the disclosed data security techniques may enable access sharing functionality utilizing the blockchain. For example, access sharing may be utilized to share policy information. The policy information may be associated with a smart contract. Accordingly, the policy information may be encrypted using a public key for the smart contract and compiled into a block of the blockchain. In response to a request to provide access to the information to a particular node, the private key for the smart contract may be encrypted using the public key for the particular node and compiled into a block of the blockchain.

Abstract: Methods and systems for processing a blockchain comprising a plurality of immutable sales records corresponding to sales made by agents of an entity are provided. According to certain aspects, a transaction request indicating a sale made by an agent of the entity may be received at a first node. A block including a sales record indicating the sale made by the agent may be added to a blockchain and transmitted to another node for validation. The first node may add the block to a copy of the blockchain, where the block may be identified by a hash value that references a previous block in the blockchain that includes at least one additional sales record.

Abstract: A system for fabricating a composite part using a 3D printing machine. The system includes means for forming the part by depositing consecutive part layers each including rows of filaments made of a part material from the machine, where depositing each part layer includes non-sequentially depositing one set of a plurality of filaments so that a gap is formed between the filaments and then depositing any number of additional sets of filaments so that each adjacent pair of filaments in each additional set of filaments are non-sequentially deposited.

Abstract: A method for fabricating a composite part using a 3D printing machine. The method includes forming a support structure by depositing consecutive support structure layers including rows of filaments made of a support structure material from the machine on a build plate, smoothing out a top surface of the support structure after it is formed, and forming the part by depositing consecutive part layers including rows of filaments made of a part material from the machine on the support structure.

Abstract: A method for fabricating a composite part using a 3D printing machine. The method includes forming the part by depositing an alternating sequence of first part layers including rows of filaments made of a first part material and depositing second part layers including rows of filaments made of a second part material, where the second part material is different than the first part material and provides adhesion between the first part layers.

Abstract: A 3D printing machine for fabricating high performance 3D integrated composite structures, where the machine includes a robot having a base portion, a robot arm and a rotatable connector secured to the arm opposite to the base portion, at least one source of an extrudable material, and an end-effector mounted to the rotatable connector and including at least one extruder module for extruding the extrudable material. The extruder module includes a nozzle assembly for extruding heated material out of the end-effector, and the end-effector is rotatable relative to the structure by the rotatable connector so that the nozzle assembly can be oriented normal to the part in different orientations without significantly changing a pose of the robot.
