Design and development of Portable 3D Printer

Project Description The 3D printer is quickly beginning to revolutionise the way people can become their own engineer. 3D printing is a quick and convenient way to create prototypes and models. The fact is that 3D printers are heavyweight and not easily portable. So in this model have focussed on design of portable 3D printer in a wooden briefcase without taking the printer out and it doesn’t need any external support for mounting. Also the choosing of wooden material as briefcase makes it eco-friendly and construct it economically. The bed area of our 3D printer is (120*120*3) mm3. We are using 4 axis mechanism where 3 axis are X-Y-Z and the 4th axis is an extruder. The process adopted by us is FDM technology.   Steps – Methodology

• Market Value And Benchmarking
• Technical Specification Finalise
• 3d Printer Product Design
• System Engineering (Multi Diciplinary) Like ME,EEE,ECE Electrical Wire Hardness
• Product Validation
• Design improvement
• Final design
• Quality control & Inspection
• Manufacturing Bill of Material
• Product Delivered for manufacturing.

  Design Process

• Design of various parts of 3D printer
• Assembly of the whole 3D printer.
• Analysis and Simulation of the printer with material addition.
• Wire harnessing and System Engineering
• Live Rendering.

  Product Functionality

• Foldable-  This makes the 3D printer easy to use and portable.
• Portable-  Transportable quality makes it work anywhere as per users need.
• Eco-friendly- The wooden briefcase makes it environment friendly as it is  disposable.
• Lightweight- The materials used in the printer makes it easy to lift and carry.
• Cost-effective- It is inexpensive and can easily be bought by average income users.
• Low Maintenance-  This product doesn’t require much repair cost if any of its part gets damaged.

• 3D printing is the rising technology.
• The demand has grown especially in the field of agriculture, biomedical, architecture, defence etc.
• If given opportunity portable printers can create wonders which can save both time and money.
• People with average income are opting for 3D printing both for self-use and business.

                Conclusion

• From a sense to print is a system that can automatically generate ready -to -print 3D CAD models.
• It uses low cost Kinetics sensor.
• The 3D prints currently generated are full models.
• They create replicas in more expensive materials such as other copper and other materials.
