Achieve lower costs than cutting processes! The production of three-dimensional products using PEEK (polyether ether ketone) is realized with a 3D printer!

In the production of three-dimensional products using PEEK (polyether ether ketone), injection molding is mainstream for large lots, while machining is the norm for small lots. For three-dimensional products made of PEEK, we have started contract processing using FDM (Fused Deposition Modeling) 3D printers with PEEK filaments produced by our company. This significantly reduces waste and allows for cost reduction. Additionally, with 3D printing, it is possible to create hollow or honeycomb structures internally, enabling material cost reduction and weight savings compared to machining, which can only produce solid forms. 【Features】 ■ Weight reduction: It is possible to achieve weight savings by creating hollow or honeycomb structures! ■ Cost-effectiveness: There is no material waste from machining, making it economically advantageous! ■ Precision: Production is possible at the intermediate level of JISB0405! (Consultation required) ■ Advancement: Due to the FDM method, it is possible to create shapes that cannot be accommodated by machining! *Please inquire as there may be limitations based on the shape. *If we are unable to produce after receiving an order, we will not charge for the costs incurred.

Recently, fine bubbles, which are tiny bubbles smaller than 100 μm and are referred to as "fine bubbles," have attracted attention in various fields such as the environment, agriculture, food, fisheries, and medicine, due to their ability to impart various functions to liquids. Fine bubbles are classified into two types based on their size: microbubbles and ultrafine bubbles. Recently, there has been a growing interest in ultrafine bubbles, which have a lifespan of several weeks to months. However, listening to the voices of researchers and users reveals some skepticism, which has become one of the issues hindering the spread of fine bubble technology. On the other hand, we have challenged the elucidation of the stabilization mechanism of ultrafine bubbles from a new perspective by enabling the control of number density exceeding 10 billion particles/mL without pressure or concentration operations using our ultrafine bubble generation technology. In this seminar, we will provide a fundamental explanation of fine bubble technology, including the basic physical properties, characteristics and functions, device technology, measurement and evaluation methods, and case studies, to promote research and utilization of fine bubbles based on a correct understanding.
