Types of 3D Printer Filaments and their uses – Part 1 - Makenica

Choosing the suitable 3D Printer filament for 3D printing services is critical to achieving the desired performance. Inappropriate material selection will result in unfavorable 3D printing ventures and wasted time, resources, and effort since certain 3D printers cannot or are not suitable to print such filament forms. 

If you are new to 3D printing in Bangalore, it is critical to be familiar with the available filament materials and their printing characteristics and properties.

Polylactic acid (PLA) has surpassed ABS as the most common 3D printer filament among 3D printing Bangalore enthusiasts. This thermoplastic is biodegradable. It’s made from natural materials like corn starch or sugar cane. 

As a result, PLA-based 3D printer filaments are much less harmful to the atmosphere than other plastic components. It is even referred to as “green plastic.”

Another great advantage of PLA filament in 3D Printing Bangalore is that it does not emit an unpleasant odour when printed. As a result, pollution in the home and classroom are relatively safer. And since the plastic does not compress as much when it cools, you do not need a heated bed on your 3D printer.

PLA’s structure is more rigid than ABS’s, resulting in slightly fragile printed objects. The substance melts at temperatures ranging from 180°C to 230°C.

PLA 3D Printer Filaments Characteristics:

• The primary advantages are high strength, ease of use, reliability, and some impact resistance.
• Ideal for household goods and small toys, with faster print rates and finer layers.
• It has fair to excellent longevity, but it can distort when overheated.
• Flexibility is minimal, and it is slightly brittle.
• It is not soluble.
• Less durable than ABS
• The standard print temperature range is 180°C – 230°C.
• Minor shrinkage during cooling, but less susceptible than ABS.
• There is no need for a heated bed.
• Once the temperature, bed height, and speed are set, printing difficulty is easy.

ABS (Acrylonitrile Butadiene Styrene) is the second most commonly used 3D printer filament for 3D Printing in Bangalore. This thermoplastic is inexpensive, sturdy, mildly flexible, lightweight, and easily extruded, making it ideal for 3D printing in Bangalore.

It’s the same plastic that’s used in LEGO bricks and cycling helmets. However, there are many drawbacks of using ABS filament, so it has fallen out of favour of 3D printing services. First, it takes a higher temperature to achieve a melting point, which is typically in the 210°C – 250°C range.

A heated build platform is also needed. This prevents the first layers of the print from freezing too fast, preventing the plastic from warping and contracting until the object’s construction is finished.

Another disadvantage of this 3D printer filament in 3D Printing in Bangalore is the strong fumes generated during printing. They can be hazardous to individuals (or pets) who have respiratory problems. The 3D printer should be installed in a well-ventilated environment. When in use, you mustn’t breathe in the fumes.

ABS 3D Printer Filaments Properties:

• The primary advantages are long-endurance, high strength, and impact resistance.
• Ideal for mechanical parts, vehicle components, electronic housing, and toys.
• Exceptional longevity
• PLA is more flexible, with slight folding before snapping.
• Acetone Solubility
• Not considered for Food safety 
• Curling and warping are common problems when printing with ABS.
• After printing, it is simple to process. The general print temperature range is 210°C – 250°C.
• To monitor cooling speed due to shrinkage during cooling, a sealed chamber is recommended.
• A heated bed between 50°C and 100°C is strongly recommended with this filament for 3D Printing services.
• The printing complexity is mild, and it necessitates fine-tuning of the bed and nozzle temperatures.

PETG – the next all-arounder – is a co-polyester 3D printer filament composed of PET and Glycerol. Eastman Chemical Corporation also markets it as Amphora AM1800. In contrast to another kind of thermoplastic that is being repurposed for 3D printing services, it has been specifically designed. The distinction is slight but essential.

The main advantages are high flexibility and endurance, as well as strong strength. It emits little to no odours during printing, has a higher melting point than PLA, and has increased layer adhesion for a smoother surface finish. Even since it is a plastic material, you can recycle it properly or use recycled material for 3D Printing in Bangalore.

PETG 3D Printer Filaments Properties:

• The primary advantages are high strength, high stability, longevity, and lightweight construction.
• Because of its high impact resistance and longevity, it is ideal for mechanical pieces.
• Highly pliable, more so than PLA or ABS, and even PET.
• It is not soluble.
• For food safety, consult the manufacturer’s recommendations.
• The standard print temperature range is 220°C – 235°C.
• Minor shrinkage occurs during cooling.
• There is no need for a heated bed.
• The printing complexity is mild, and it necessitates fine-tuning of the bed and nozzle temperatures.

Polyamide, also known as Nylon, is a widely used synthetic polymer in various industrial applications. Nylon 3D printer filament is a low-cost plastic that is solid, compact, flexible, and resistant to wear. It also has a lower brittleness than PLA or ABS. It is much heavier and more robust than the other two.

Nylon 3D printer filament has a wide range of uses. Machine pieces, containers, equipment, household goods, and toys are among them. Oh, and another thing: you should stain it with fabric dye. 

If you keep your spools dry, 3D printing nylon is pretty easy. Otherwise, you could encounter difficulties. Since Nylon filament easily absorbs humidity from its surroundings, it should be protected from humidity while in storage.

But it doesn’t end there. Taulman, a 3D printing services filament maker, has produced many varieties of nylon filament. It is up to the consumer to determine which variation is the best fit for the intended use of the 3D printed object.

Taulman nylon 618 is a high-quality industrial material. It is ideal for prototyping as well as finished products. Essentially, what distinguishes nylon 618 is its excellent layer bonding when printed at 245°C, and all other settings are set accordingly. Furthermore, nylon 618 does not emit any fumes. What seems to fume is Water evaporating during printing.

Since it is possible to 3D print online very high quality, chemical resistant, and airtight products, this form of Nylon can be machined after printing and used as the substrate for casting moulds. Please keep in mind that glass and aluminium surfaces are not suitable for nylon 618 print beds. Instead, use a rougher or more fibrous fibre, such as unfinished wood or Garolite. 

Taulman nylon 645 is a higher-quality variant of nylon 618. Despite being almost equal, nylon 645 has higher tensile strength and greater layer bonding. In contrast to nylon 618, which is invisible, it is transparent. 

Taulman Bridge nylon is a less expensive alternative to nylon 645 spec nylon. Bridge nylon, which was developed in response to a wide variety of consumer demands, also satisfies certain desirable characteristics such as excellent tensile strength, improved first layer adhesion, affordability, decreased water absorption, opacity, and reduced shrinkage.

TPE is widely used in manufacturing car components, home equipment, medical products, window and door temperature sealing, shoe soles, electrical insulation, handset covers, and wristbands.

These flexible 3D printer filaments can create extremely stretchable artefacts by using thermoplastic elastomers (TPE), especially Polyurethane (TPU). They can withstand the punishment that neither ABS nor PLA could.

 However, it can be challenging to deal with because the material has an annoying propensity to squeeze out of the extruder in all ways except the nozzle during the 3D Printing services.

TPC is another lightweight 3D printer filament that, unlike TPE/TPU, is ideal for outdoor use.

In the food industry, High Impact Polystyrene (HIPS) material is widely used for packaging. HIPS 3D printer filament is biodegradable and has a light white colour; it has no adverse effects when in contact with humans or pets.

The purpose of HIPS filament in 3D printing services is not to create the object itself; the material has curling and adhesion issues, making it challenging to work with (especially if you don’t have a heated bed).

Instead, it’s a common secondary material in dual extrusion 3D printers in the 3D Printing services. It gives structural support to a complex object, the centre of which is printed in ABS.

The 3D printer filament can be dissolved using a colourless liquid hydrocarbon after the print job is over. It vanishes as if by magic!

• When combined with ABS, the primary advantages are the dual extrusion support system.
• ABS support framework that is easily removable
• Exceptional longevity
• Low flexibility, with only slight folding before snapping. Soluble in a variety of solvents.
• Food safety is not considered.
• The standard print temperature range is 210°C – 250°C.
• To monitor cooling speed due to shrinkage during cooling, a sealed chamber is recommended.
• Heated bed at temperatures ranging from 50°C to 100°C.
• The printing complexity is mild, and it necessitates fine-tuning of the bed and nozzle temperatures.

When printing an object in PLA or ABS with overhangs that would otherwise be difficult to print, polyvinyl alcohol (PVA) 3D printer filament is usually used as support. PVA, like HIPS, is an excellent filament for 3D printers with dual extruders.

This material is non-toxic and biodegradable since it is built on polyvinyl alcohol, and it can be dissolved in water.

This 3D printer filament is compatible with all popular desktop FDM 3D printers, including a heated build base. It is important to remember that printing temperatures do not reach 230 C with this type of 3D Printing in Bangalore.
