Ck) and BRRI dhan33 (R. Ck) as checks were tested at farmers’ field in eight locations such as West Byde (BRRI Gazipur), Khulna (Dumuria), Habiganj (Sadar), Chapainawabganj (Gomostapur), Rangpur (Sadar), Feni (Dagonbhuyan), Chattagram (Hathazari) and Barishal (Sadar) during the season of Transplanting Aman 2018. The trial was replicated three times in each location. The unit plot size was 17.94 m2 (4.6m x 3.9m). Seeding emergence for eight locations varied from 11-17 July 2018. Seedling age varied from 25-30 days among the locations. Seedlings were transplanted at 20 cm x 15 cm spacing. NPKS and Zn fertilizers were applied at the rate of 0, 15, 50, 12 and 3.6 kg ha-1, respectively. All fertilizers except urea were applied as basal whereas, urea was applied in 3 equal splits at 10, 25 and 40 days after transplanting (DAT) Other standard management practices were followed as and when necessary. No inse...

A machine that allows this process is known as a 3D printer. It has several components. The major components of a 3D printer are frame, Head movement mechanics, (Stepper) Motors, The print head/extruder, Firmware, 3D Software, etc. In this research, it was attempted to describe the design and construction process of a Fused Deposition Modeling (FDM) 3D printer with the help of a traditional 3D printer. The 3D printer was used to print different-designed parts of our targeted 3D printer designed by Computer-Aided Design (CAD) software. After the construction and firmware installation, four different prints of different sizes were done and the resulting outputs were analyzed.

The splitter was designed by using Solidworks software for connecting with specific lmm core diameter fiber and fabricated directly by an FDM 3D printer. NOA glue were used to fill up the core, on the other hand, the design structure of substrate and cover layers was fabricated by ABS polymer. Then, an efficient ultra-smoothing technique was applied and the insertion losses of the splitter were measured.
