Which 3d printer filament should I choose for my 3D printer?
FDM technology is one of the most widely used 3D printing processes on the market due to its ease of use, accessibility and performance. It is known especially for its compatible with a variety of thermoplastics. Today, most plastics in the industry can undergo this transformation, thus expanding the field of possibilities. But how do you choose your filament for your 3D printer? What characteristics need to be taken into account?
Standard 3D printer filaments
PLA Filament, or polylactic acid, is considered greener because it is biodegradable under the right conditions. It is very easy to use this 3d printer filament, which is why it is very popular in the 3d printing market. It is mainly used for prototyping, tooling, decorative parts or in the medical sector.
ABS filament is well known for its resistance to low temperature shocks and its lightness. It is not always easy to classify this material: it is sometimes in the technical part of the pyramid and is less easy to process than PLA for example. Its properties make it an ideal material for the production of functional prototypes, tooling parts that are often solicited or in the manufacture of molds.
PETG filament Polyethylene Terephthalate Glycol-modified (PETG) is a tough and durable materials and it is easy to use. The strength of it allow to be a suitable material for food packaging, the chemical non-reactive characteristic allow it to be the most valuable material in medical field, normally used for orthopedic and prosthetic device.
iSANMATE 3D high performance PETG filament is based on FFF/FDM technology, with a commonly used diameter of 1.75 mm, 210-235ºC printing temperature, 50-80 ºC bed temperature, having excellent inter layer adhesion which greatly improve the strength and shock resistance of the prototype.
Nylon filament,also known as polyamide (PA), is more prevalent in the additive manufacturing market in powder form for SLS technology. However, it can be found in filament form, available with 6 carbon atoms, hence PA6. PA6 is known for its resistance to impact and abrasion as well as its flexibility. It has a fairly long life, ideal for the production of parts such as hinges, machine components and tooling. It can be reinforced with carbon or glass fibers.
Technical 3D filaments
Polycarbonate 3D printer filament(PC filament) is primarily used for its strength and transparency. It is particularly popular in the optical industry because it is less dense than glass and can withstand temperatures ranging from -150°C to 140°C. Typically, protective screens or optical parts can be 3D printed with polycarbonate.
High performance 3D Printer filament
PEI filament PEI 1010 is an amorphous polymer that have excellent thermal properties, exceptional dimensional stability, good chemical resistance, and inherent flame retardancy. As the glass transition temperature () can reach up to 217°C, which allows PEI to print parts with excellent property.
iSANMATE 3D high performance PEI 1010 filament is based on FFF/FDM technology,370 ℃ -390℃ printing temperature,130℃-150℃hotbed temperature and 90°C-150°C chamber temperature which allow it to have excellent inter-layer adhesion, which greatly improve the strength, durability and shock resistance of the prototype.
PPSU filament is a type of high temperature aromatic sulfone polymer. For a long time, it has been considered as one of the most excellent composite polymers in plastic field. PPSU can be used under a high temperature of 180ºC, PPSU has an excellent hydrolysis resistance and able to resist common acid and bases over a broad temperature range.
iSANMATE 3D high performance PPSU filament is based on FFF/FDM technology, with a diameter of 1.75 mm, having excellent inter-layer adhesion, which greatly improve the strength, durability, and shock resistance of the prototype.
PEEK filament is probably the most common 3D printer filament. it requires an extrusion temperature of about 752°F (400°C), a plate that can reach 446°F (230°C) and an enclosure heated to 248°F (120°C). PEEK is known for its weight/strength ratio and can withstand high temperatures. It can be sterilized, which makes it the material of choice for printing custom implants. It is a filament for 3D printers that remains demanding, requires a certain mastery of the 3D printing process and remains quite expensive.
