A Complete 3D Printer Buying Guide

In recent times, 3D printing technology is a rapidly emerging technology. It has begun to interfere in our everyday life. From medical to education, manufacturing to research, the use of 3D printing technology is increasing in every field. So if you are serious about buying 3D printer, this guide is for you.

 Before buying a better 3D printer, first of all make sure to check these points one by one:
  • First, find out what work you are using 3D printer for
  • Identify the 3D printer which is best for you
  • Choose a suitable size and shape
  • Check the safety measures
  • Look for high quality features
  • Cost of a 3D printer

First, find out what work you are using 3D printer for

There are different types of 3D printing technology which are used for different types of works. Some 3D printers are used at home level and some are used for industrial purpose. There is a huge different between these two types of 3D printers. So if you want to buy a 3D printer then you must know the types and materials used in a 3D printer.

Art work

If you want 3D printer for an art work then FDM (Fused Deposition Modeling) resin printer is a best option. There are different types of resin - Standard resin, Tough resin, Medial-grade resin. Basically standard resin is use for art work.

Professional work

Various professional work from various industries from automobile to aerospace use 3D printers to create original components.

Medical fields

Various medical components and dental works use medical - grade resin for printing.

Outdoor designs

In outdoor designs like lawn decoration and plant pots PLA (Poly Lactic Acid) or PETG (Polyethylene Terephthalate Glycol) is used as a material in 3D printer.

Identify the 3D printer which is best for you

There are many types of technologies used in 3D printing. It is very important for you to know these technologies and their uses.

FDM (Fused Deposition Modeling)

FDM (Fused Deposition Modeling) uses thermoplastic filament. In FDM objects are created by heating the thermoplastic filament and then extruding the thermoplastic layer by layer. The material is extruded along X,Y and Z axis.

SLS (Selective Laser Sintering)

SLS (Selective Laser Sintering) uses a powder material. In this printer powder material is placed in a vat. A roller placed this powder material as a layer on top of the previous layer and then powder material is solidified by focusing a laser beam according to a certain pattern. This is how an object is created in SLS printer.

SLA (Stereolithography)

SLA (Stereolithography) uses liquid resin as a source material. This printer uses photo - solidification process by using UV (Ultra Violet ) laser. UV laser focuses on a point to solidify liquid resin.

DLP (Digital Light Processing)

DLP (Digital Light Processing) is very similar to SLA (Stereolithography). This technology uses more conventional light sources. When light focused on a point in the resin, the resin starts to harden quickly. The object printed on DLP printer is smoother than the FDM printer.

EBM (Electronic Beam Melting)

EBM (Electronic Beam Melting) is very similar to SLS (Selective Laser Sintering). This technology uses an electron beam instead of a laser beam. This process is slower and more expensive than SLS technology.

Filament Materials

  • PLA (Polylactic Acid) - PLA (Polylactic Acid) is derived from renewable resources such as starch or sugarcane. It tends to deteriorate after prolonged exposure to sunlight or excessive moisture. So this material is used for indoor applications not outdoor applications.
  • ABS (Acrylonitrile Butadiene Styrene) - ABS (Acrylonitrile Butadiene Styrene) is a thermoplastic polymer. ABS requires a lot of heat to be setup. Hence it is suitable for enclosed 3D printer.
  • PETG (Polyethylene Terephthalate) - PET stand for Polyethylene Terephthalate and G means it's been Glycol modified. It is a food safe plastic. It is more flexible than PLA or ABS.
  • Resin - There are different types of resins used for different works. Medical-grade resin is used for medical purpose. Standard resin is best for printing small objects and prototypes. For different professional and engineering works tough resin is used.

Choose a suitable size and shape

Filament Diameter

Filament comes in mainly two diameters : 1.75mm and  3mm. 1.75mm diameter filament is quicker to heat-up. The printer is designed for one size filament. So it is not possible to mix different sizes without changing the hot end and extruder. 

Nozzle Size

Most machines comes with 0.4mm nozzle size but nozzle of 0.3mm size becoming more popular.

Layer Height

Layer height means how thick the each layer is. The common layer height is 0.15mm or 0.2 mm. The layer height is adjustable.

3D Printing Volume

3D Printing Volume means that how large a size can be print at once. The size of the printing volume depends on the chosen material and the type of printer.

Check the safety measures

3D printers contains a lot of moving mechanical parts. So it is advised to add any protections identified by users.
 Different types of material with different origin is used in 3D printers so be careful while using these materials.
 Check the power supply unit used in 3D printer which protects against short circuits and overloads.
 3D printer has several heating elements. So check the heat carrying capacity of the elements.

Look for high quality features

3D printer with high quality features makes your experience better. High quality features includes touchscreen user interface, heated glass bed, dual filament support and many other features. Resolution of  a 3D printer also matters a lot. 3D printer resolution measured in microns.

Cost of a 3D printer

Cost of a 3D printer varies with quality and style. In general, high quality 3D printer cost is above $1000. Professional printers can even go above $2000. Although its price is decreasing due to full competition. If you are beginner, you can start with simple models that go for as low as $100.
