Imagine a time when you can 3D print anything and everything in your own house or your neighborhood.If you need a dish plate, a broken piece of your device, a machine part or just a toy. Or why just a toy, you can 3D print your jewelry, your broken car parts, or your dream house in which you want to live your whole life. Or why just a house, your doctor can print a prosthetic arm, skin or an organ in the worst case you need it. Many of these things are achieved and the rest of these will be achieved in near future and this time is not far away from the present. Then the only limitation to print will be your imagination. 3D printing is revolutionizing the present with its miracle like transformation in technology. This article will cover all you need to know about 3D printing and the objects you can 3D print in various industries in short.


3D printing (or additive manufacturing) is a process which is used to print an object in three-dimension, layer by layer under computer control. Unlike material removed from a stock in the conventional machining process, 3D printing or additive manufacturing builds a three-dimensional object from computer-aided design model by successively adding material layer by layer.
Objects can be of any shape and are produced using digital model data from a 3D model. It can also be produced by an electronic data source such as an Additive Manufacturing File (AMF) file. Stereolithography (STL) is one of the most common file types that 3D printers can read.


1. Modeling

3D printable models may be created in many ways. It can be created with a computer-aided design (CAD) package, via a 3D scanner, or by a plain digital camera and photogrammetry software. To reduce the errors, 3D printed models should be created with CAD and the errors can be corrected easily before printing, allowing verification in the design of the object before it is printed.

2. Printing

The CAD file needs to be converted into the STL file and this needs to be processed by a piece of software called a “slicer,” which converts the model into a series of thin layers and produces a G-code file containing instructions to a specific type of 3D printer. During the 3D printing process, this G-code is used to instruct the printer, which is done using a 3Dprinting client software.

3. Finishing

The resolution produced in 3-dimensional printing is sufficient for many applications, but when a slightly oversized version of the object is desired then removing material to get higher precession and better surface finish with a higher-resolution subtractive process is better.

What objects can a 3D printer print?

A coffee mug, high heels, hanging lights, iPad stand, acoustic guitar, a wheel rim or a whole car, a house plan, a cement wall or a whole house, a prosthetic arm, synthetic skin, bone….. the list is too long. So let us see a detailed list in each of the industry, what we can print and what cannot be printed.

Check this list-

1.Daily household things

It will be fun if we can customise our daily used objects as per our desire. You will not need to search some remote shop or ask your friend where I can find it. Your object, your design, your colors, sounds nice, but of course, we cannot print with any material. Hope this can also be done in 3D printing in coming years. Let us see a list of some objects-

wooh.. that was a lot of things.


2. Automobile Industry

companies are adopting 3D printing for jigs and fixtures.3D printing jigs and fixtures can lower costs, provide lighter and more ergonomic tools, and more. Furthermore, it has shown a consistent reduction in lead-time by 40% to 90% and cost reduction up to 60%. 3D printing rapidly designs a prototype saving precious time of the design team allowing them to concentrate on other important design aspects. In 2014, Local Motors printed the first 3D-printed car from an ABS carbon-fiber blend (about 80/20 respectively) called Strati.

Today, the company has three models and an autonomous electric-powered shuttle named Olli. Also, Honda released a newer version of the Micro-Commuter in October 2016. A single-seater with about a 50-mile driving range, the body and majority of the panels on the Micro-Commuter are 3D printed.

Yes these cars are 3D printed



3. Architecture Industry

Architects, Engineers, and Construction (AEC) professionals understand the paramount importance of accurate and tangible scale models. It helps them and their clients visualize ideas realistically and vividly. Traditional ways of designing and assembling a scale-model are time-consuming, and are very costly, and rely heavily on skilled craftsmen.

3D printing will revolutionize the way architects designs and innovate their ideas. 3D printing for architects empowers them easily create complex, accurate and durable scale models quickly and cost-effectively. The 3D printed models can be used to demonstrate and impress the clients, seizing more opportunities, all this in a matter of clicks.



4. Aerospace Industry

From complex engine parts to cabin interiors, aerospace companies are turning to the capabilities of 3D printing to produce better performing parts for their commercial aircraft and/or spacecraft. The ongoing development of the industry itself will surely lead to more breakthroughs in the near future. In the aerospace industry, the benefits of adopting 3D printing will be reduced material weight, part consolidation, improved part performance, virtual warehouse, and many more.



5. Electronics Industry

With 3D printing replacing the conventional manufacturing processes, in the electronic industry opportunities are growing in terms of ease of customising a product for a user or a customer. The production of relatively low volumes is possible in the industry because of 3D printing. Like for example, if the small startup needs to make 30 pieces of their product, by the conventional process the initial setup would be too costly and it will not justify the cost of a single piece of product.



6. Foundry

Producing sand molds and cast metal parts is a relatively straightforward job and suitable for automated methods. The most common method is to produce aluminum patterns, fabrication of which is often very difficult, expensive and time-consuming. These aluminum patterns are machined using a CNC machine. The biggest problems with this approach are the high cost and long lead time. On the CNC machine, the intricate gate and runner systems cannot be produced. So, the gate and runner system are cut from Ren board and then hand carved to the finished shape.

The problems associated with traditional pattern production are many and this process takes much time and money. So foundries have long been interested in 3D printing. With 3D printing systems available, foundries can fabricate patterns with either inkjet-based technology or FDM Technology. This results in savings, in cost, labor and time, ultimately speeding new product development.




7. Medical

3D printers are used to manufacture a variety of products in the medical industry. It includes those products with complex geometry or features that match a patient’s unique anatomy.Sometimes a standard design is copied to make multiple identical copies. Other devices are called patient-specific devices. This type of devices is created from a specific patient’s imaging data.

Commercially available 3D printed medical devices include:
Implants (e.g., cranial plates or hip joints), and
External prostheses (e.g., hands).

Manufacturing of living organs such as a heart or liver via 3D printing process is in early stage of development. Scientists are still researching such methods and process.

Things that can be 3d printed are-

Tissues with blood vessels


Low–Cost Prosthetic Parts




Tailor-made sensors

Medical Models




ear cartilage



medical equipment

Cranium Replacement



8. Jewelry

Many startups have been seen in this field recently.A 3D printing startup from Hong Kong, called POESIS, has successfully completed its crowdfunding campaign for a smart 3D printing jewelry system. This system allows anyone to easily create unique and resilient rings and bracelets. A study by YouGov, a prominent data research firm, indicated that marketing efforts by high-end jewelers for Millennials are proving to be inefficient. This market-segment is spending approximately $49 billion annually on products within various luxury categories, however, only a limited percentage of this money is being spent on fine jewelry.
