Intech additive solutionsone of the leading end-to-end providers of metal additive manufacturing systems, additive manufacturing software design and additive manufacturing, has collaborated with Bhabha Atomic Research Center (BARC) to design and 3D print miniature metal components.
Miniature metal components are an essential element in critical applications of miniature robotics (bio-robotics), especially in the field of personalized electroporation devices such as drug delivery, food pretreatment, cosmetic therapy of the skin, etc.
These components, given their size and complexity, making the items and delivering them in a timely manner is a challenge with conventional methods.
Metal 3D printing technology is an ideal ally for scenarios such as the manufacture of miniatures, complex and semi-sculpted components due to the design and economically feasible solutions.
Intech Additive’s iFusion LF series of printers have the capability to manufacture small to large metal parts for multiple industrial applications. The systems are designed to achieve high build rates, manage optimized cost per part (CPP) and cost effective manufacturing.
Some of iFusion’s features include automated powder handling, part removal, and powder sieving. iFusion has one of the largest build volumes in its class of 450 x 450 x 450mm. The system uses AMOptoMet and AMBuilder software from Intech.
AMOptoMet is a new alloy parameter development software. It is tuned to calculate and optimize the processing parameters of a given alloy for Laser Powder Bed Fusion (LPBF) technology.
AMBuilder is build processing software. His part orientation, support generation, and path generation helped in preparation for building the miniature component.
BARC provided the initial designs of the miniature components for possible adaptation to the AM process. Intechs DfAM expert team suggested and implemented other design changes for optimal component operation.
“In my opinion, Intech engineers have a good sense of technical brilliance, practicality and leadership. I have observed that engineers follow ‘first principles thinking’, which is very essential for any off-the-shelf indigenous solution for new technologies,” said Dr. Debanik Roy, Scientist, Telemanipulation and Robotics Division, Bhabha Atomic Research Center, in a letter of appreciation to Intech Additive.
Roy also said in the letter, “I’m proud to say that in the space of six months, Intech engineers have reached the pinnacle of authentic product-focused manufacturing with the perseverance and passion that comes with it. impose.”
The 3D printed component created by the companies is a miniature monolithic metal component with an overall length of 33mm, a cylindrical case and a tapered front face. The crucial part of the process was printing a tiny retaining ring, 1.5mm thick and 0.9mm center hole diameter. The workability of this retaining ring is essential for the actuation of the component.
The component had to be assembled with another part, the “end-cover”, having a height of 6.5 mm. The completed component assembly is now fully functional and can be used for a variety of applications after additional instrumentation.
Bhabha Atomic Research Center is a premier nuclear research facility in India, headquartered in Trombay, Mumbai, Maharashtra. It was founded in 1954 as a multidisciplinary research program essential to India’s nuclear program.
Intech Additive Solutions is based in Bengaluru, Karnataka in India, a region that is also home to the airport city of Bengaluru, where a state-of-the-art 3D printing facility has recently opened. Intech describes itself as “a pioneer in developing solutions that enable our customers to effectively adopt additive manufacturing technologies”. Intech’s mission is to keep innovation alive, drive digital transformation, and enable faster adoption of additive technology to meet local and global manufacturing demands in a long-term sustainable way.
