The main objective of our project is to re-design the hydraulic manifold and fabricate the prototype using 3D printing to reduce weight, improve flow performance and reduce the cost. The simple existing industrial manifold block is designed using CAD software. Then analysis of the flow field characteristics and change in pressure of right-angled flow passage of supply line and return line is carried out in the typical hydraulic manifold block which is made from the conventional manufacturing process. Then to redesign the industrial manifold effectively with angled flow passage and analyze the optimization level. This modified design mainly reduces the major loss in the fluid called pressure loss and reduces the velocity of fluid during the change in direction of flow. As we are in the era of industry 4.0, the fabrication of this product is to be made with the currently emerging technology called additive manufacturing. Another reason to go with AM is because of the complex structure of this manifold. It will significantly reduce the production time and machining cost. Our project comes up with producing the 3D printed prototype of the modified manifold from the industry.For this analysis process, we have selected the materials Aluminium alloy (AL 6061-T6) and Stainless steel (SS-316), because of their high strength to weight ratio and low material cost. Hence it will reduce the overall production cost and it will greatly reduce the weight.

3D-printing is an innovative manufacturing methodology. In this 3D-models can be set up using computer aided solid models. Those are digital files. A part is created in this method by establishing layers of material one over the other until the total part is formed. These layers can be thought of as a thin material slice. These methods are widely used in life-sciences, footwear, aerospace, automobile, jewelers and biomedical engineering. ‘Stereo-lithography’, ‘FDM’, ‘SLS’, and ‘EBM’ are different forms of printing techniques. Through these 3D-printing methodologies complex shaped parts can also be device with increased correctness. This paper explains the comparative study of electron beam melting with selective-laser-melting

3D Printers are playing a huge role in helping to fight against COVID-19.3D Printing also known as additive manufacturing, refers to processes used to create a three-dimensional object in which layers of material are formed under computer control to create an object. With 3D printing innovation these days, we can easily transform any design into a 3D model. The utilization of 3D Printers in medical fields are growing quickly and are required to reform human services. The corona virus infection-19 has spread all over the world and stances diverse challenges to healthcare offerings. Health care staff rely on Personal Protective Equipment to protect themselves and their patients from infection. Hospitals around the globe are running out of PPE for treating COVID Patients. The constrained accessibility of PPE has impacted many countries ability to react to the emergency. The 3D printing network is ready to overcome this international scarcity. The target of the current work is to examine the 3D printing innovation with regards to a Covid-19 pandemic and to analyze which kind of PPE can be printed utilizing 3D Printers. The beneficial 3D prints for Covid-19 are Face shield mask, Safety goggles, nasal swabs, Ventilators, Oxygen Venturi valves, hands-free door openers, Tweezers, Handy tool for buttons, Respirator mask, 3D Printing pill dispenser, medical devices and surgical tools and so on.

This project is to fabricate the most essential parts of Delta type 3D printer parts so as to make it more efficient in cost and working. This project has 3 vital parts of a 3D printer and they are Effector, Rod end bearings, Connecting rod (Diagonal rod). The Effector is a component that holds the hot end nozzle and other heat dissipating material within it and we in our project made a multi utility Effector so as to hold many hot ends such as Laser cutting, CNC tool, Food extrusion and 3D printing hot end. This Effector is also categorized into two as uphold and bottom hold since uphold and down hold. Rod end bearings are the motion transmission bearings that would transmit motion in a spherical path. We have made a different mechanism to transmit the motion same as to rod end bearing by coupling two universal joints and making some modification in it and made it cheaper in cost and efficient in working process. The connecting rod is the linking rod between the carriage and the effector. This connecting rod is used to transmit the motion from the carriage to the effector and this works in accordance to the design imbedded on the printer. The conventional 3D printer has carbon fibre pipes as their connecting rod and in this project this connecting rod is changed to steel and this one is made so as to withstand the load acting on it and cost efficient. All these parts are connected and made as a single setup and can be used in any delta type 3D printer. The overall cost of this setup is ½ times the cost of the conventional setup.
