3d Printer Guides

What is 3D printing ?

3D printing is the process of converting any digital file into a real 3d object. You can draw using CAD design software or scan any object you would like to get into real object or you can simply download any files from the internet. 3D Printing is also known as Addictive manufacturing in which printed object is formed by successive layers by layer of print material .This materials can be plastic,metals,concrete,food paste or even biological cells printing human tissues and organs one day .

3D Printers were originally developed by some inventors in late 1980’s. Hideo Kodama from Nagoya Municipal Industrial Research Institute of Japan invented  AM fabricating methods of a three-dimensional plastic model with photo-hardening polymer hardened with UV light . In July 16, 1984 Alain Le Méhauté, Olivier de Witte and Jean Claude André filed their patent for thestereolithography process also known as SLA filed for the patent but it was later known that their employer abandoned it considering it lack of business perceptive . During same period Inventor Chuck Hull from US applied for patent 3 weeks before and was awarded the patent and was known as “ the father of 3D printing “. In 1986 Chuck Hull established 3D Systems in Valencia , California .

The 3D Printing gained worldwide momentum when Dr Adrian Bowyer a senior lecturer in mechanical engineering from University of Bath , UK founded Replicating Rapid Prototyper ,RepRap. RepRap is a open source project to develop and modify 3D printers design . The aim of RepRap project is to give the the technology for 3D printing as desktop manufacturing system that will allow individuals to manufacture artifacts and tools used in everyday life . Later many individuals joined and contributed to the RepRap community and developed many models . Many models available commercially  in market are derived from RepRap project . 

3D printing now has been great impact in many industries such medical, science, engineering, aerospace, education and many more. At 3Dprinterkart we help you get best 3d printers available in market at best prices so that you can transform your concept & ideas into reality !

How 3D Printing works?

Different type of printers uses different technology but the basic thing need to understand the process is done layer by layer. Some printers uses plastic , Binder powder, Resin , Paper , metals etc .

FDM (Fused Deposition Modelling) is used widely because its cheap and affordable . In FDM , layers of plastic is deposited on one over other , raw material used here is plastic .

Another widely used technology is SLA (Stereolithography) which uses photopolymer resins as material and UV light laser to cure the resin layer by layer . DLP (Digital Light Processing) is similar kind technology in which projectors are used as light source to cure the resin . 

SLS (Selective laser sintering) is a technique that uses a laser as the power source to sinter powdered material (typicallymetal), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure. Other type of 3D printers are Direct energy deposition , Sheet lamination and newly developed Ink Jet Fusion .

In 3D Printing the 3D CAD file like stl,obj,dae,amf,bmp etc and 3d scanned file is imported in to software which is called slicer . The software creates numbers of horizontal layers of the object and generates tool paths , material used and time taken in gcode format . There are many open source slicer as well as paid or propriety slicers like Cura , Repetier , Slic3r , Kisslicer , Octoprint , Simplify3d(paid) etc .

How to choose 3d printer ?

At 3Dprinterkart we help you choose 3d printer which best suits your needs .

It most depends upon the application you intend to use 3d printer for .

If you wish to learn the working of 3d printer and modifications we would recommend you to buy DIY printers . You can even buy DIY if budget is a restriction . But do remember that making a 3d printer is a learning phase it may take time to understand the assembling . People with good technical background in electronics may find easy but for others it may take some time . If you have time and patience on can opt for DIY

There are beginners model 3d printer which usually come semi-assembled or assembled but cheap . It may have very basic functions lower priced and a bit lower accuracy . You can tune up the printer for more accuracy but it solely depends upon on your expertise . You can save considerable time and money and it’s a good option for starting up with 3d printers and knowing the application . These printers are usually used by beginners , students , Engineers and maker space.

Pro 3D Printers are firm and steady build by the manufacturer , well tried and tested with tuned settings.

It will print out of the box with minimal setup .If you do not have time to spend on assembling printer or tuning it and  If you are a professional service provider and your sole purpose is to print models for your own use or provide services  then always opt for  pro 3d printers . This printers are bit expensive but do have lot of features to offer . Such printers have good stability , longer life service , warranty and support from the manufacturer . It can be used for quantity 3d printing production purpose also . Such printers are usually used by Educational institutions , maker space , Prototyping service providers and professional 3D designers .

FDM can be used for making prototype for industrial samples , toys , designers projects , Schools & Colleges , maker space and as a personal desktop printer . Parts made in FDM printers if made with proper infill and good filament can be used in direct applications also .

SLA & SLS and used where high level of accuracy and details are needed like jewellery designing , micro industrial parts designing etc.
