7 Advantages of 3D Printing

Are you aware that there are many advantages of 3D Printing. To make any parts there are different methods of manufacturing. First is subtractive manufacturing, where material is removed from solid block such as metal. This is done manually or by CNC (Computer Numerically Controlled) machinery. Other being Injection Moulding process for mass production. 3D Printing is an Additive Manufacturing process where 3-dimensional part made computer , its file is connected to a 3D Printer where layer by layer the material is deposited and a part is made. Today many companies are making full advantage of 3D Printing process over the more traditional manufacturing method of substractive manufacturing and Injection Moulding. To know what are the advantages of 3D Printing please read my blog till the end.

There are 7 advantages of 3D printing as compared to conventional machining process, they are as follows.

 

1. Flexible design

By 3D printing we can design more complex design compare to conventional manufacturing process. Normally traditional designing process has design restrictions whereas in 3D printing  it Let  us try to understand 5 Benifits of 3D Printing Technology is not so.

  

2. Quality 

 

 

Conventional manufacturing process can result in to poor designs, therefore quality products prototype. If all process is not done as per specific method the prototype may fail in conventional machining. Whereas in 3D printing it allows the step-by-step assembly of the part or product, which enhances the design and better quality part/product is guaranteed.

 

3. Consistency 

 

In conventional manufacturing process the quality of parts depends upon the batch, either defective or inconsistent or good.  Whereas in 3D printing parts are printed in succession. Each successive individual part can be monitored, which makes us convenient to detect whether the part made is good or bad quality, thereby reducing the failed parts wastage and continuously improve quality of the parts being produced.

 

4. Accessibility

 

3D printed parts are much more accessible and can be used by a much wider range of sector than traditional manufacturing setups. Compared to huge investment for conventional manufacturing process, 3D printing set up is much less. Also 3D printing process is almost completely automated, thereby no additional person is required to monitor the process, which makes much more accessible than other manufacturing systems bye good margin.

 

5. Sustainability

 

3D printing technology is more environmentally friendly process, then conventional manufacturing process.

a) Less transport is CO2 emission
b) Lighter product
c) Easy repair of parts
d) Less wastage
e) Environmentally friendly materials
f) Recycled filaments

This shows that 3D printing is sustainable process

 

6. Speed

One of the biggest advantages of 3D printing technology is rapid prototyping. Ability to design, manufacture and test a customised part in a less time. Also if needed design can be modified instantly, without affecting the production time.

 

7. Cost

 

3D printing is the most cost effective manufacturing process. Conventional machining prototyping methods requires CNC machining and Injection molding, which requires expensive machines and labour cost for this is very high due to skilled operator. Where as in 3D printing process only one or two machines are required and few operators are required to manufacture a part. Less wastage of material is there and it is an additive process and not material is carved out from a solid block.

 

So 3D printing is the future of the manufacturing industries.If you like this Blog, please comment below.

5 Most Applications of 3D Printing Technology

While 3D printing has been around 30 years, its popularity and usage increased in recent year. Earlier 3D printing was costly as cost of 3D printer and filaments used were costly. In recent years there is a lot of improvement in technology and variations in both the machines and material used, thereby cost have come down, making 3D printing applications more accessible and cost-effective, across all industries and education. To know 5 most applications of 3D Printing Technology read my blog till the end.

Myself Ravindra Gavde, Next Gen 3D Guide, founder of Facebook group "Mission 3D for Generation Next" and my mission in coming 3 years is to prepare career seeking 10000 students for future opportunities in 3D Printing.

1. Prototyping and manufacturing

3D printing was first developed for faster prototyping. With conventional injection molded prototype it cost thousands of rupees and also takes weeks to produce a single mould. Again after making 1st sample piece if any changes are to be made, die is to be modified, then again take sample. Go on till the part is perfect. The rework of die costs lot and the die is with lot of reworks, looks shabby too. where as 3D printing technology reduces the time to make sample piece after making a 3D model on CAD software and make the part on 3D printer. Any changes required can be made on CAD model and again 3D print the sample. Once approved and finalised do reverse engineering and make injection moulding dies. Which can be made in hours instead of weeks and that too at the fraction of the cost as compared to conventional method.

2. Construction

3D printing can be used for fabricating buildings are construction components. Extrusion (concrete/cement, foam, wax and polymers), bonding powder (reactive bond, sintering, polymer bond) and additive welding are used for construction. The first building was constructed in Russia in 2017. More than 500 elements of the wall where printed in a shop and assembled on site, followed by roof top and interiors for around 3,000 sqft. This project has passed all building requirements, for design, building permit, registration, to connection of all engineering systems. Today a family lives in it.

3. Art and jewellery

Nowadays 3D printed parts are used for art and jewellery products. Creative design not possible with conventional jewellery making methods can be easily 3D printed. Jewellers as per individual taste can be made, customised pieces at lower cost, using 3D printing materials such as PLA, Gold and Platinum. Artist all over the world use metal 3D print to create beautiful intricate pieces, Sculpture, Ceramic Vase. Recently the Prado museum in Spain had exhibition of paintings of well-known artists rendered in 3D. The purpose was to allow blind persons to feel this work that were previously inaccessible to them.

4. Education

Students can prepare for their future by making prototypes without expensive tooling. Student learn about 3D applications by designing and making model they can physically hold. Companies such as MakerBot offer certification courses in 3D printing application for teachers and students. Students from science can create and study cross-section of organs in the human body. Chemistry student can make 3D models of molecules and chemical compounds. Graphic design students can make models with complex workable parts.

5. Medicine

In last several years many applications of 3D printing in medicine has been developed. Bioprinting is one of them, where bio materials such as cells and growth factors are combined to create tissue-like structure imitating their natural counterparts to medical devices like prothetics. It is difficult and expensive to produce prosthetics that fits a patient. But by 3D printing technology it is lower in cost and also new prosthetics can be 3D printed for growing children's every few months. 3D printing is used for producing porous metal orthopedic implants, which easily integrate with the patient's own natural bones, allowing them to grow into the implant.

These are the few of the countless applications of 3D printing technology from Prototype to Construction to Education to Medicine to Arts, which has huge impact on world today.

3D Printing Technology, Process explained in 6 steps and what can be made

Most of them think that 3D printing is to print photos or print newspapers. But it is not so, it’s three dimensional part been made on a 3D Printer. The difference between conventional machining and 3D printing is that in conventional machining we remove material and make a part, whereas in 3D printing it's an additive process thereby layer by layer material is deposited and parts are made. Following are the few Parts made by 3D Printing.

                                 

To know more about 3D Printing Technology, its Process, and what can be made please read my blog till the end.
 
I myself Ravindra Gavde, NextGen 3D Guide, founder of the Facebook group "Mission 3D for Generation Next" and my mission in the coming 3 years is to prepare career-seeking 10000 students for future opportunities in 3D Printing.

Let us understand the 3D Printing process in 6 steps.

Step No. 1 - CAD Model   

First to make a part 3D Model is to be made with all actual dimensions. This 3D CAD Model can be done by 3 types of most commonly used software. The first is Google Sketchup, the second one is Autodesk Fusion 360 and the third one is Solidworks. Out of this Google Sketchup is a free software available on the net. In this software, you can see how the part will look actually. If you want you can change any dimension or shape at this stage.

 

Step No. 2 - STL FILE (STEREOLITHOGRAPHY - STANDARD TRIANGLE LANGUAGE)

 

After 3D CAD Model is made, STL File has to be extracted from this and saved. In this file, only part shape is considered and not it's colour nor its texture. This file is automatically created on the Software used during CAD modeling. This STL file is send to Slicing Software.

 
Step No. 3 - Slicing Software

 

Then STL file is processed in the Slicing software where CAD Model is sliced into layer after layer. This is done because the 3D Printing will be making the part layer by layer. To have an idea it is shown in the above images of CAD Model and Slicing the Model. The most commonly used Slicing Softwares are Makerware, CURA, and Simplify 3D. Out of this CURA is free software available on the net.

Step No. 4 - Layer Slices and Tool Path

In Slicing software, it is decided how much thickness of the material is to be deposited in each layer, how much temperature of wire filament should be kept depending upon the filament used, and the rate of depositing the material is decided. Also, it is defined how the part orientation should be as it should not be overhanging while the material is deposited. Necessary supports are decided at this stage. These supports are removed after the part is made completely on a 3D printer. All this is in G-Code and this G-Code file is sent to the printer to print the part.

 

Step No. 5 - 3D Printer

Finally, this G-Code file is copied on a Pendrive and connected to the printer. The most popular 3D Printers are Ultimaker and Makerbot. Here the colour of the wire is attached to the printer and the printer is started and the part is generated layer by layer. These layers get attached to each other and dry immediately because of their properties. In this process after each layer, the table moves down and layer after layers are deposited. Finally, the part is made.

 

Step No. 6 - 3D Part

After the part is made on a 3D printer it has to be finished manually by removing supports if given. Also, polish paper is applied wherever necessary. Modern 3D printers almost print finished parts and not much finishing is needed.
 
After getting to know how 3D printed parts are made in 6 steps, let us now watch a video of how a 3D printer makes an Eiffle tower.

Why 3D Printing Technology should be part of Formal Education

 

Do you know why understanding 3D Printing Technology is absolutely essential for today's secondary kids? Do you know after Artificial Intelligence, Internet of Things, 3D Printing Technology is the greatest next-gen thing that is happening and all school children should know about it.

          

Education of today needs to understand the true potential of 3D printing in education. Today's classrooms should be places of practical application and have hands-on experience. Due to its versatile nature 3D Printer can help students to use real-world applications, the knowledge in different fields such as Mechanical Engineering, Science, Architecture, etc. To know more about it please read my blog till the end.

Myself Ravindra Gavde, NextGen 3D Guide, founder of the Facebook group "Mission 3D for Generation Next" and my mission in the coming 3 years is to prepare career-seeking 10000 students for future opportunities in 3D Printing.

Let  us try to understand 5 Benefits of 3D Printing Technology           

1. Creative inventors

 

3D printing Technology makes students a creator. They invent based on needs and create solutions instead of buying or consuming the creations of someone else. Students use 3D printers to create a prosthetic hand for children around the world. Given the right tools, support and resources, you can imagine what any innovative invention would your son or daughter can create.

2. Engaging reluctant learners

 

Some people learn by seeing, some people learn by listening and some only by doing and 3D printing will ensure that they are actually kinesthetically involved in creation so they will be more engaged. Since 3D printing is a very new technology, it is not available to the average consumer. It's that excitement that can engage students who would otherwise have nothing to do with their learning. This is a wonderful new way to teach any motivate students. They are excited and eager to learn new things. The overall enthusiasm towards school and learning has increased tremendously in developed countries. Students who are typically reluctant learners have come to life. Students who are absent now and then have improved their attendance and are eager to learn more about it.

3. Solving real-world problems

3D printing exposes students to the real world and make them face real-world challenges, does making them fighters. 3D printing technology is the new sensation in the market. It makes education more realistic and practical. It sharpens the student's minds and makes them more practical and more creative in their approach. Thus it's the best technology for students.

4. Prepare students for the job of tomorrow

 

In recent years 3D printing has moved from a development lab in to manufacturing products out on the shop floor. 3D printing is considered a slow process but for prototype product, its works out to be the cheapest compared to the conventional machining processes. 3D printing speed is doubling every two years and will continue to do so. Students learning every aspect of 3D printing will prepare them for the job of tomorrow.

5. Students learn CAD along the way

To make a part on a 3D printer, a 3D CAD model is to be made. While making a model all information is needed such as size, shape, etc. The printer will be printing the model layer by layer. For that slicing software is needed, Cura is an open-source program for slicing. The software breakdowns the CAD model into G-code. Which contains all the commands that control the speed and direction of the printed head as it deposits layer after layer of extruded plastic to form a 3D model. Thus students learn CAD along the way in the process.

3D printing is changing the world and has an impact in fields as diverse as Aerospace, Fashion, Architecture, Engineering, and Medical. 3D printing skills developed by students will serve them well, regardless of their chosen careers.

Following are the fields where 3D printing can be made use of.
