3D printing is based on the concept of constructing an object in sequential layers that display the contours of the model. We describe what materials are used in 3D printing.

If you are interested in the characteristics of materials, then you need to visit this page.

The most common 3D printing method is extrusion (FDM). Standard parameters for FDM 3D printing: layer height – 0.2 mm, nozzle diameter – 0.4 mm, wall thickness, top and bottom floors – 1.2 mm. Below are the main materials used in this printing method:

PET-G 

This material is by default in the automatic costing system. In 90% of cases, customers choose this material. We also recommend it most often. This material solves most problems and has an excellent price-quality ratio. The material combines the positive features of such materials as: ABS (high strength), PLA (excellent precision and non-shrinkage). The material has a high chemical resistance to acids, alkalis and organic solvents. Possesses high wear resistance. Among other things, the material is relatively easy to machine.

Polylactide (PLA)

PLA is an environmentally friendly, biodegradable material made from corn and sugar cane. Plastic absorbs moisture well and is not suitable for functional use (an exception is an unloaded plain bearing, since PLA has a high slip coefficient). It is used for making designer models, souvenirs and toys. It is widely used in 3D printing of prototypes because it has the highest accuracy among materials in FDM technology. Great for making mockups as it is non-toxic and accurate.

WAX 

We recently started using WAX in FDM printing. Perfect solution for burnout products. The best solution for foundries when it comes to large items. No shrinkage which indicates good accuracy of products.

Acrylonitrile butadiene styrene (ABS)

ABS is widely used in industry: the production of car parts, cases of various devices, containers, souvenirs, various household accessories, etc. ABS plastic is resistant to moisture, acids and oil, has a fairly high thermal resistance – from 90 ° C to 110 ° C. Unfortunately, some types of material degrade when exposed to direct sunlight, which somewhat restricts their use, but plastic is easy to paint and you can apply a protective coating to the finished product. It has a large shrinkage, therefore it is printed only in a closed chamber.

Styrene-butadiene styrene (SBS)

SBS (Styrene Butadiene Copolymer) is a high quality 3D modeling material, great for 3D pen creativity and design. SBS has an amazing combination of properties: a high level of hardness and high elasticity which remains even at low temperatures. The absence of shrinkage allows printing large models while the models retain their elasticity – they are difficult to break or split. Unique dyeing formulations allow to obtain models with bright, crystal clear colors. Easy processing of finished models (solvent or D-limonene) unsurpassed brilliance and transparency make SBS an indispensable material for striking design solutions.

Acrylonitrile (ASA)

The material is highly durable and resistant to external factors. It is also UV resistant and virtually unaffected by lubricants, dilute acids and diesel fuel. Compared to ABS plastic, it is resistant to ultraviolet light, has increased adhesion and a noticeably less heat shrinkage effect. The material is perfect for printing cases of outdoor devices, street lighting equipment, elements of cars, marine and aerial equipment (both external and internal elements) and items that are exposed to the environment during operation.

CERAMO

A unique material that imitates ceramic products. It has no analogues in the market of consumables for 3D printing. Hard, durable with excellent adhesion between layers. Ready-made prints are practically indistinguishable from faience and ceramics in their tactile properties. Hard, pleasant to the touch, cool, heavy and sonorous on impact.
The material lends itself perfectly to abrasive materials, emery papers and can even be polished mechanically with fine abrasive finishing emery papers. Wet sanding is recommended.

Heat resistance of the material, exceeding the boiling point of water (up to 102 ° C), allows it to be used for printing unique tableware (for example, souvenir cups). All polymers and fillers used in the production process of the CERAMO material are food grade and are suitable for contact with hot food.

Nylon

Nylon is a man-made thermoplastic polymer also called polyamide. The characteristics are similar to ABS plastic. Nylon has high wear resistance and low friction. Therefore, it is often used to cover rubbing parts, which improves their performance and often allows them to function without lubrication. This type of plastic in the form of filament is used in 3D printing using FDM technology, and in the form of a powder can be used in SLS and other similar methods.

Thermoplastic polyurethane (TPU)

Sealant (TPU) thermoplastic polyurethane. The most resilient and durable material in the REC range of flexible plastics. Differs in high chemical resistance to oils, gasolines, alkalis and some acids. Possesses high strength in bending and tensile deformation. In addition, the polymer has good resistance to seawater, grease, and is not susceptible to microbes or bacteria. The material has a high level of resistance to natural aging and is recyclable.

Composite (TPU GF, TPU CF)

Thermoplastic polymer, on high-grade carbon or glass fibers. In terms of its characteristics, it surpasses ABS, PLA and SBS in terms of: non-carcinogenic, ultra-strong, matte surface, insoluble in solvents, does not absorb moisture, soft – better amenable to mechanical post-processing, better tolerates environmental conditions. It can be used as the main material of the product.

In addition to FDM technology, we have the ability to print from:

Resin (SLA, MJP)

A substance that changes its properties under the influence of light, more often ultraviolet light. Mainly soft and light sensitive material before exposure to light. Resin is used in dental prosthetics for filling forms, in the manufacture of printing plates for stamps (seals), microcircuits and printed circuit boards, and in other fields. The highest manufacturing precision. The difference is that SLA technology has treelike supporting structures while MJP technology is paraffinic. The SLA has a layer height of 50 micrometers while the MJP has 32 micrometers.

Polyamide (SLS)

Structural polymer material with good strength and antifriction properties. This polyamide is chemically resistant to oils, gasoline, alcohol, weak acids, diluted and concentrated alkalis, and is non-toxic. Layer height 0.1 mm. The minimum wall thickness is 1 mm.

Metal (SLM)

Stainless steel 1.4404, (316L), 1.2709, 1.2344, Aluminum AlSi10Mg and others on request. Layer height 0.1 mm.
