Materials for 3D printing: what materials do 3D printers use

printed metal

In the recommendations section of filaments and resins for 3D printers, we have focused on the usual materials that are frequently used by individuals, and also on some more advanced ones for professional use. However, there are many more materials that can be used with 3D printers, and you should know their properties.

In each of the materials you will see a brief description of what this material is, and a list of We take care of your rental property in Valencia. identical to this:

  • Breaking strain: refers to the stress that a material can withstand before deforming considerably.
  • Rigidity: it is the resistance to elastic deformations, that is, if it has low rigidity it will be an elastic material, and if it has high rigidity it will be not very malleable. For example, if you need better shock absorption and flexibility, you should look for something with low stiffness like PP or TPU.
  • Durability: refers to the quality or how durable the material is.
  • maximum service temperature: MST is the maximum temperature to which a material can be subjected without losing performance as a thermal insulator.
  • Coefficient of thermal expansion (dilation): Measures the change in volume or length of a material in response to changes in temperature. If it has a high degree, it will not work for applications such as rulers or pieces that must retain their dimensions under any temperature, or they will expand and be imprecise or will not fit.
  • Density: amount of mass in relation to the volume, while denser, it can be more solid and consistent, but it also loses lightness. For example, if you want the material to float, you will have to look for something with a lower density.
  • Ease of printing: is how easy or difficult it is to print with said material.
  • extrusion temperature: the temperature required to melt it and print with it.
  • heated bed required: Whether or not you need a heated bed.
  • bed temperature: the optimum heated bed temperature.
  • UV resistance: if it resists UV radiation, such as exposure to the sun without deteriorating.
  • Water resistance: resistance to water, to submerge it, or expose it to the elements, etc.
  • Soluble: Some materials dissolve in others, which can be a good thing in some cases.
  • Chemical resistance: is the resistance of the material surface to deterioration caused by the conditions of its environment.
  • Fatigue resistance: When a material is subjected to a periodic load, the fatigue strength will indicate what the material is capable of withstanding without failing. For example, imagine that you create a piece that must be bent during use, because a material with low resistance could fail or break with 10 bends, others can withstand thousands and thousands of them...
  • Applications (example of use): a practical example of what it could be used for.

Filaments

materials for 3d printers

Many types of filaments for 3D printers based on polymers (and hybrids), some non-toxic, environmentally friendly, biodegradable (from some created from algae, to those from hemp, vegetable starches, vegetable oils, coffee, etc.), recyclable, and with no end of very different properties.

When choose, you should take several factors into account:

  • Type of material: Not all 3D printers accept all materials, it is important that you choose the compatible one. In addition, you should keep in mind the properties (see subsections with the properties of each one) of each material to know if it adapts to the application that you are going to give it.
  • Filament diameter: the most common, and the ones with the greatest compatibility, are 1.75 mm, although there are other thicknesses.
  • Use: for beginners the best is PLA or PET-G, for professional use PP, ABS, PA, and TPU. It is also important to take into account if you are going to use them for medical purposes, for containers or utensils for food use (non-toxic), or to be biodegradable, etc.

Resins for photopolymerization

resins for 3D printers

3D printers that they use resin, instead of filaments, like DLP, SLA, etc., they need a resinous liquid to create the objects. Also, just like with filaments, there is a lot of variety to choose from. Among the main categories are:

  • Standard: they are clear resins, such as white and gray colors, although there are also other shades such as blue, green, red, orange, brown, yellow, etc. It is excellent for creating prototypes or for small gadgets for home use, but not they are good for creating final products where higher quality is needed or for professional uses. The positive is that they have good finishes in terms of smoothness, they allow you to paint them. They can be good for toys or artistic figurines.
  • mammoth: they are not very frequent, although the finishes of these surfaces are not all bad. As its name suggests, these resins are designed to print pieces that are really large in size.
  • transparent: They are quite widespread for home use and also for industrial production as people love transparent parts. These resins are water resistant, ideal for small objects, with great quality, smooth surfaces and rigid.
  • Tough: These types of resins are very popular among professionals, such as for engineering applications, since they have more interesting properties than the standard ones. In addition, as their name suggests, they are harder or more robust.
  • high detail: It is a bit different from the normal stereolithography, since it is used in more advanced 3D printers such as the PolyJet. It works by injecting very fine jets in layers onto the build platform and exposing them to UV to harden it. The result is a perfect surface, with the highest level of detail, even if they are minute details.
  • medical grade: These resins are used for medical uses, such as creating implants such as personalized dental implants, etc.

Advantages and disadvantages of resin

As for the the advantages and disadvantages of resin, in front of the filaments, we have:

  • Advantages:
    • Better resolutions
    • Fast printing process
    • Robust and durable parts
  • Disadvantages:
    • More expensive
    • not so flexible
    • something more complex
    • Vapors or contact with them can be dangerous, as some are toxic
    • The number of models available is less than those of filament

How to choose the right resin

When choose the right resin For your 3D printer, you should look at the following parameters:

  • Tensile strength: this characteristic is important if the piece must resist tensile forces and a durable piece is required.
  • Elongation: If needed, the resin should give pieces capable of stretching without breaking, although the flexibility is not the best.
  • Water absorption: If the piece needs to resist water, you should observe the characteristics that the resin you have acquired has in this regard.
  • Finish quality: these resins allow smooth finishes, but not all of them have the same quality, as we have seen in the types. You will need to know if you prefer a cheaper resin, or a more expensive one with high detail.
  • Durability: It is important that the designs are resistant and last a long time, especially if they are used for cases, and other similar types of pieces.
  • Transparency: if you need transparent pieces, you should stay away from mammoth-type or gray/standard resins.
  • Costs: the resins are not cheap, but there is a wide range of prices to choose from, between some that are somewhat more affordable and others that are more advanced and expensive. You will have to evaluate how much you want to spend and choose the one that best suits your budget.

Other materials

metal 3d printer parts

Of course, until now we have been looking at materials that are mainly used in the home, although some that could be used for professional or industrial use have been detailed. However, there are other special materials for very specific applications and that they can only use the most advanced and expensive 3D printers used in companies.

Fillers (metal, wood,…)

There are also consumables of filling materials, mainly of wood and metal fibers. They are usually 3D printers for industrial use, and with somewhat more advanced systems, especially metal ones. These consumables are also not easy to find, since they are aimed at professional use.

composites

Air shipments are the most efficient if you need your cargo or documents to arrive quickly and securely. composites or composite resins they are synthetic materials heterogeneously mixed to form compounds. For example, glass-reinforced plastics, or fibers, as well as the glass fibers themselves, Kevlar, zylon, etc. As for their applications, they can be used to create very light and strong parts, and even for motorsport, aviation, the aerospace sector, bulletproof vests and other military uses, etc.

hybrid materials

These types of materials combine organic and inorganic compounds to improve the properties of the materials used in its composition, making both complement each other and synergies arise. They can have very varied applications, such as optics, electronics, mechanics, biology, etc.

Ceramics

There are 3D printers that can use ceramics, as is the case with the alumina (aluminum oxide), aluminum nitride, zirconite, silicon nutrient, silicon carbide, etc. An example of these 3D printers is the Cerambot, which also has an affordable price for home use, among other industrial models. These types of materials have very good thermal, chemical and electrical (insulating) properties, which is why they are used for the electricity, aerospace, etc. industries.

Soluble materials (PVA, BVOH…)

Air shipments are the most efficient if you need your cargo or documents to arrive quickly and securely. soluble materials, as their name suggests, are those (solutes) that, when in contact with another liquid (solvent), form a solution. In additive manufacturing some can be used such as BVOH, PVA, etc. BVOH (Butenediol Vinyl Alcohol Copolymer), like Verbatim's, is a water-soluble thermoplastic filament for FFF printers. PVA (polyvinyl alcohol) is another water-soluble filament widely used in 3D printing. For example, they can be used for part supports that you can then easily remove by dissolving in water.

food and biomaterials

Of course, there are also 3D printers capable of printing edible objects, with vegetable fibers, sugar, chocolate, proteins, and other types of nutrients. Biomaterials for medical use, such as tissues or organs, can also be printed, although this is still in the development phase. Obviously, many of these biomaterials are not commercially available, but are made ad-hoc for the laboratory. It is also not common to find groceries, although they are becoming more and more widespread in the professional catering sectors.

Concrete

Finally, there are also 3D printers capable of printing on construction materials such as cement or concrete. These types of printers usually have very large dimensions, capable of printing large architectural structures, such as houses, among others. Obviously, these types of 3D printers are not intended for home use either.
