Yarn carriers for 3D printers have certain characteristics and use very specific consumables.
Materials used in 3D printing
If you want to print in 3D you need a printer equipped with 3D filaments. It is very important to choose a range of materials and master working with the different kinds. Investigate all the possibilities.
One must know the materials that you can use with your 3D printer, many materials can be used such as plastic, metal, wood, glass, ceramics, beeswax, resin, gelatin, chocolate and even stem cells.
The 3D printer also needs to “recharge” like the classic printer.
The different types of materials
Ultimately the printing technology conditions the consumable type (filament, powder or resin), it is the printing equipment that determines the usable materials.
You must be sure of two things primarily: The first thing is the printing technology used by your printer. Indeed, each type of machine uses a printing technique that determines the range of compatible materials. Most home printers use either two kinds of printing technology, FFF (Fused Filament Fabrication) or FDM (Fused Deposition Modeling).
The second important point is the hardware required to print, for example to mold the product you will need a printing nozzle and a heating plate.
Here is a list of key mass market materials
The two main types are the FFF, FDM or filaments, liquid resins and SLA/SLS powders. They all have common characteristics that allow us to learn more about their mouldibility, solidity and their impact on the environment.
The ABS filament
It was in 1946, in the United States, that ABS plastic (Styrene Acrylic Butadière) was invented. It is currently widely used in the automotive indsutry, for sports accessories, high-tech appliances and for toys. It is recyclable but not biodegradable, this impacts on the environment because it is made from oil.
The ABS filament threads are available in two diameters, 1.75mm and 3mm, the length is about 400 meters and it weighs 1 kilogram. The price is between 20 to 25 euros per kilo. The filament comes from the petrochemical and rubber industry so its price varies according to the curve of oil prices. It is available in many colors such as blue, white, black, green, red, yellow, transparent and fluorescent.
During printing, the ABS produces good results. It is resistant to extreme temperatures (-20 ° to + 80 °). This printer must be equipped with a heating plate, or a hermetic chamber so as to reduce shrinkage. It is easily findable on online sites. Warning, do not use ABS in food because as it is plastic and thus very toxic.
There is a variant of ABS, the ABS Conductive, this variant has recently arrived on the market at $40 a kilo. The latter is encased in carbon fiber, this mixture with the carbon makes the material conductive for electricity and creates anti-static properties.
This material is very popular and has many advantages. It is however not so environmentally sustainable.
This is a material used for replacing the PET in the manufacture of plastic bottles. PLA (Poly-Lactile Acid) is a bio-plastic consumable. It is obtained through the fermentation of sugar. PLA has long been used in the packaging of packs of mineral water or for some bottles. This is one of the most eco freindly plastics.
It comes predominantly in the form of 1.75 mm wire coils, 2,85mm and 3 mm in diameter, it is heated by the printer at a temperature between 160 and 220 degrees. It cools very quickly. It also has many colours and the price is similar to the ABS. The phosphorescent costs between 7 and 10 euros, slightly more expensive than conventional colours.
This material is more difficult to use than ABS plastic. PLA is more flexible and reliable. The maintenance of the machine is more important. It less resistant to high temperatures and more fragile than its oil counterpart ABS.
There is also a variant, PLA Soft. It has a great flexibility. It is recommended to print at 210° and has a slower speed than its predecessor.
This supply is integrated in almost all 3D printers because there is no need for a heating plate or chamber. It allows one to acquire a 3D printer that is reasonably priced and efficient. The positive quality is that it is biodegradable and biocompatible. The negatives are little resistance to heat and sensative to moisture..
The nylon filament
This is a polyamide that has been developed by Wallace Carothers in 1935. This polymer can be produced either naturally or artificially. It manufactures proteins. The polyamides are often used in the textile, automotive industries etc … because they are very durable. The supply is available in powder or filament. The polyamide is used for artificially unnatural 3D printing. that is why we speak of Nylon coils. This material is not biodegradable because it is also derived from petroleum. Think carefully about what you want to do.
Nylon is in the form of wire coils and typically weighs 450 kg and measures 1.75mm and 3mm in diameter. It’s melting point is between 235 ° and 260 °. The nylon coils are white, black or a natural colour. The price is quite fair, between 30 and 40 euros for a 450 kg roll. This material absorbs moisture. You will need to store it in a dry place. This material is not yet widespread. In conclusion fares are accessible and much stronger than PLA or ABS. It is more stringy and deforms more than ABS or PLA negative.
The filament Goemon
This is a filament made of seaweed. It is still in testing, so not yet commercially available. but the it will be avaliable very soon. To create this filament, over a year of research will have been conducted. It is produced in Saint Malo. This is filament is the most environmentally friendly on the market. It is made from wild kelp harvested in Brittany. They do not consume water or arable land and they do not use pesticides or fertilizers for growth. It is a filament coil like it’s counterparts in the market. The measures have not yet been disclosed. It’s marketing is imminent and we’ll have more details soon, it is biodegradable and the greenest of all the filaments present in the market. It is a real and potentially revolutionary alternative to the plastics used in 3D printing.
