3D Printing verses Conventional Machining

 

In 3D printing material is deposited only whatever is needed to make a part since it is an additive process, whereas in conventional machining material is removed, subtracted, thereby scrap is generated and part is made. To know more about 3D printing let us compare 3D Printing verses Conventional Machining please read my blog till the end.

1 - Rapid prototyping

Prototyping can be done quickly from design. Once the 3D model is made on software as per requirement, it can be made quickly after defining actual manufacturing on 3D printer with help of slicing software and layering software. Once this is done, connect a pen drive where this program is ready to a 3Dprinter. 3D printer will start manufacturing part layer-by-layer in no time.

 

2 - Waste Prevention

In 3D printing, only material is deposited to make that part layer by layer, with no extra material, so there is no wastage at all as compared to conventional machining, where from solid block or rod material is removed to make part. Thus the material removed in conventional machining to make part produces wastage too, which goes into scrap

 

3 - Creating complex geometries

 

Compared to conventional machining, more complex geometries can be produced since it is an additive process. Those complex geometries are often lighter and stronger to compared to conventional machined part. With conventional methods, a highly complex part cost more to make than to make a very simple one, whereas in additive manufacturing the process is same for complex part, thus no additional cost.

 

4 - Freedom of design

By use of new optimisation software it gives freedom to design and produce organic shapes and light-weight structures. Conventional machining has to adhere strictly to the design of manufacturing. However 3D printing the additive manufacturing process eliminate this concern since any design is possible, as long as you have right support material.

 

5 - Adaption to production with 3D printer

3D printing is typically used for prototype parts, it can be quickly expanded to production, ready to use parts and finished products. In conventional machining to finalise the part, it is normally done on CNC machine till the part is ok which costs more than normal machining, whereas in 3D printing it costs the same for prototype as well as for production.

 

6 - 3D printing and the future of manufacturing business

3D printing are not only more productive but are also for environmentally friendly. Normally when you make any part with conventional method, it has scrap leftover. A 3D printer knows the mould and design and build only what is needed. Thus 3D printed parts are more economical and earth friendly. 3D printer also has the advantages of becoming a productive manufacturing tool. With commercial 3D printer, higher production volumes can be achieved and larger products can be designed.

7 ways, 3D printing will change the world

3D Printing Technology applications are almost in every industries in the world due to that lot of investment and research is being done. It has been widely used to develop prototype from scratch to replacement of machine parts. It is widely used in footwear, fashion design, construction, automotive industries and in the aerospace industry. In fact, at the rate it is going, 3D printing being one of the most promising technology that could change the world. To know how 3D Printing will change the world please read my blog till the end.

1 - Replacement available 24/7

 

Best part of 3D printing to the world is any part can be made available 24/7. Instead of storing the part, just by placing order you can print a part and deliver at your doorstep. You can print exact number of pieces you need, rather than buying in bulk. There are many 3D printing websites that gives you everyday use part to 3D print.

 

2 - Automaker using 3D Printing

Biggest advantage of 3D printing is that it can be used for rapid prototyping. Car manufacture uses 3D printing to create custom, complex and higher performance parts. Many car manufacturers are using advanced metal 3D printing technology to create for more detailed, micro-scale precision parts. In future, you could eventually just 3D print the car of your dreams, rather than simply go out and buy a car.

 

3 - 3D Printed Homes

All over the world the cost of home are increasing day by day. Many people are actively trying to reduce the carbon footprint in many ways possible, including the construction of their homes. 3D printed homes are more eco-friendly, zero waste, no transportation cost and can be recycled. In many developing country are building low-cost 3D printed house almost 10 houses a day at low cost as $ 5000 (3.75 Lakhs) in a small space. Their process uses “ink” made from fiber glass, steel, cement, binder and recycled ruble.

 

4 - Custom Apparel

Made to order Apparel can be 3D printed, for example if a shoe size is between 6 and 7, you can 3D print as per your size. That 3D printed shoe gives special strength and lightness to the shoes, made up of carbon fiber 3D printed material. The same analogy goes to 3D printed clothes. You can design your own clothes too. Maybe one day 3D printing will replace traditional textiles.

 

5 - 3D printed food

Oil and powder cartridges will be used to create nutritional meals with regular required calories. This will reduce food waste considerable as a cartridges will have a 25 + years of shelf life. Some printer today are used to print chocolate, simple candies and even a pizza.

 

6 - Prosthetics will be cheaper

Free editable designs are even available online for prosthetists and amateurs. Anyone can, who has 3D printer and has do it yourself mentality can create a prosthetics at low cost. Prosthetic arms, hands, legs and feet can be made.

7 - Use in space Station

To go at space station it takes lot of fuel and preparation and whenever something goes wrong in space, there may be limited spare parts available there. Till that part is arrived astronauts may need to wait till the next mission to space. Alternative to this is with 3D printer on space, they can print part there itself or other items as and when needed during emergency. Even 3D printed food supplies for astronauts is manageable.

This list is largely incomplete. There are many ways 3D printing will change the world and will continue to update it.
