The following describes the types of filament


ABS Filament(acrylonitrile butadiene styrene) is a strong and durable plastic.

 

ABS is because of its strength and toughness useful for the manufacture of toys which among other things is famous for the production of LEGO bricks.

 

ABS has a tendency to warp / bow ends up during printing, if there is no proper adhesion to the print base. Therefore, it is recommended that the heated build platform is 100-120 ° C to avoid wrapping, in order to get a good print result of your 3D print.

 

Before you begin to 3D print, it is important for the attachment of the filament, that you clean the build platform.


Heating the ABS may cause vapor and other gases, which some persons find uncomfortable, and good ventilation is recommended to prevent this.

ABS has a high thermo-tolerance and is non-degradable (opposite the PLA, which you can read about in the description below of PLA).

The 3D printed ABS bends rather than shatter under load.

 

Advantages of ABS:

• Supporting parts easy to remove

• High strength

• Can be polished by acetone to get smooth surface


 

PLA Filament(polylactic acid) is bio-based. PLA is produced from cornstarch. Since it is made of starch, then it is degradable under hot and humid conditions.

PLA is hard and brittle. The surface is finer, more detailed, and also slightly shinier.

 

PLA has the following advantages: no smell, a lower melting point, a good flow through the extruder, and no need for post-processing.

 

PLA is a hard and strong plastic that is not easily to twist.

The 3D printed PLA has under load tendency to shatter, rather than bending as ABS.

The temperature range where the filament extrudes is about 180-210 ° C.

PLA has a low melting point and prints fine without a heated build platform and therefore save energy. Often is a fast speed possible with PLA.

 

Advantages of PLA:

  • Smooth surface
  • Can be printed with large size without wrapping
  • Environmentally friendly to biological degradation
  • Can be 3D print at lower temperatures than other plastics, so it costs less on energy bills



HIPS Filament (High Impact Polystyrene) is one of the most produced polymers worldwide. It is a flexible product commonly used in food packaging industry because of its strength, hygiene, and ability to retain heat.

 

HIPS Filament is a great filament for beginners, because it is easy to use.

HIPS have similar properties like ABS, because it is relatively strong and can be sanded.

Unlike ABS, HIPS has no potential to warping during printing and is ideal to paint. And therefore it is popular for use to costumes, models and miniatures.

HIPS Filament is ideal, as support material together with other filaments, to print objects with inner cavities intricate sections, overhanging, and much more.

HIPS Filament is great to use as a soluble support material (easily dissolved in Limonene).

The temperature range where the filament extrudes is about 220-240 ° C.

 

Advantages of HIPS:

  • Fabulous as support material can be dissolved in Limonene
  • high strength
  • Easy to print with

 

Nylon Filament is a synthetic polymer which is composed of many devices using of amide bonds. Therefore it is called substance often polyamide. It was the first synthetic fiber that was made entirely from inorganic raw materials: coal, water and air.

Nylon is a fantastic strong material, when your items must have strength and some flexibility so it does not break.

To achieve the best possible shiny deep color brilliance, simply print with a higher resolution nozzle and at a slightly lower temperature.

Be careful not to go so far down in the temperature, so that the filament loses bond strength.

Nylon is sensitive to moisture. Therefore it is very important to make sure to keep Nylon filament dry before printing to prevent steam from the hot end and bubbles in the finished printed subject.

Nylon can be dyed before or after printing.

The temperature range where the filament extrudes is about 240-260 ° C. And the hot end must be able to handle up to 270°C.

 

Advantages of Nylon:

  • High strength
  • Low weight
  • Can be printed with large size without wrapping
  • Not waterproof

 

 

PET-Glass Filament (Polyethylene terephthalate) is a plastic resin of the polyester family, which also used to make beverages, food and other liquid containers.

PET-Glass has some very interesting properties in terms of clarity, mechanical, thermal and electrical properties as well as high strength.

The temperature range where the filament extrudes is about 220-240 °C.

Advantages of PET-Glass:

• Very high strength

• There are no odors or smoke when printing

• Very low shrinkage makes printing large planar surfaces a breeze

• It's easy to print on acrylic, glass, Kapton and other platforms

• Smooth surface

• Environmentally friendly to biological degradation

 

Flexible Filament (TPE = Thermoplastic elastomers), sometimes referred to as thermoplastic rubbers. TPE is a class of copolymers or a physical mix of polymers (usually a plastic and a rubber), which consist of materials with both thermoplastic and elastomeric properties.

You can 3D print amazing things with this flexible filament, phone case, bracelet, molds, shoes, and only your creativity is the limit.

Your extruder gear must be optimized for flexible filament with only a few mm gap between driver gear and the hole for the HotEnd.

The temperature range where the filament extrudes is about 200-220 ° C.

Advantages of Flexible:

  • Flexible and compressible surface
  • Can be printed with large size without wrapping
  • Environmentally friendly to biological degradation

 

Wood / Straw Filament contains half PLA and about 30% straw or wood flour.

You will get amazing 3D printed items after printing, where the filament will smell like, look like and can be handled like wood.

Depending on the printing temperature can cause it to look similar wood objects:

  • If the temperature is varied up and down during printing, so it will look like wood with growth rings
  • At low temperature it gets a light color
  • At higher temperature it gets a dark color After printing the item may be processed - cut, sanded or painted.Wood / straw-like materials generally have the same printing properties as PLA.The temperature range where the filament extrudes is about 215-245°C.

Advantages of Wood / Straw:

  • Near zero warp
  • Rough or smooth surface possible during one print
  • Heated build plate is not required
  • Excellent flow properties

 

Pellets ABS

ABS Pellets naturel, an affordable way to buy plastic for your 3D printer, as a substitute for filament, you can with ABS pellets extruder your own filament using filament extruder or if you have the option to print directly with pellets in your 3D printer.

ABS(acrylonitrile butadiene styrene) is a strong and durable plastic.

 

ABS is because of its strength and toughness useful for the manufacture of toys which among other things is famous for the production of LEGO bricks.
