Standard plastics (HAGE3D – VALIDATED)
ABS (acrylic-butadiene-styrene copolymer) is an often used, mechanically high-quality material with high heat resistance. ABS is a thermoplastic and amorphous. It is tough and resistant. The butadiene content makes ABS impact resistant. It can be smoothed with acetone.
ASA (acrylonitrile-styrene-acrylic ester copolymer) is comparable to ABS, with the difference that acrylonitrile has a much higher resistance to aging and weathering. It is thus the “ABS for outdoor applications”.
PP (polypropylene) is a semi-crystalline standard thermoplastic and has a low density, medium toughness, low strength, average heat resistance, but low scratch resistance. PP is resistant to chemicals. PP is the “better” polyethylene, reinforced with fillers, it can even compete with engineering plastics such as PBT at not too high operating temperatures.
PETG is a glycol copolymerized variant of polyethylene terephthalate (PET), the latter commonly used to make water bottles. PETG is an amorphous
thermoplastic with good mechanical performance, it is strong, tough and impact resistant. The hardness is lower than at PLA e.g. and it is prone to abrasion under high stress. The material also benefits from the excellent thermal properties and it is virtually distortion free. PETG also has a high chemical resistance. PETG is a “wolf in sheep’s clothing” that combines the advantages of ABS (temperature resistance and mechanical performance) and PLA (high pressure resolution) and extends it with chemical and UV resistance.
Because it can be printed at low temperatures, does not require a heated print bed, has a high print resolution, and has very low warpage, PLA is the most popular material for filament-based material extrusion. PLA is thermoplastic, semi-crystalline, hard / brittle with low impact strength and heat resistance. It is made from grains such as corn and sugarcane and is renewable and above all biodegradable.
ABS (ACRYLIC BUTADIEN STYRENE COPOLYMER) FLAME RETARDANT
ABSpro – Flame Retardant is an advanced, halogen-free ABS that meets the UL 94 V-0 Flammability Standards requirement and extinguishes within 10 seconds of ignition.
The filament has a high content of polycarbonate (PC) and contains halogen-free, flame-retardant additives to fulfill the flammability.
Technical plastics (HAGE3D – VALIDATED)
TPE (THERMOPLASTIC ELASTOMER)
TPE (thermoplastic elastomer) is the generic term for all rubber-like plastics which, unlike real elastomers (“rubber”), can be processed by extrusion. This is achieved by a morphological “blend” of thermoplastics and elastomers. As the name suggests, this amorphous material is elastic at room temperature, so that the plastic has a high flexibility. There are several types of TPE, with material extrusion most commonly used being thermoplastic polyurethane (TPU) and thermoplastic copolyester (TPC). The degree of elasticity of the plastic depends on the type of TPE and the chemical formulation used by the manufacturer. For example, some filaments may be partially flexible like a tough car tire, while others are highly flexible like a rubber band. TPE’s are abrasion and chemical resistant and have a low to medium tendency to warp.
The semi-crystalline thermoplastic PA (polyamide) is very tough as PA6, very hard as PA6.6 and very dimensionally stable as PA12 in media contact. In general, PA has outstanding mechanical properties (combination of strength, hardness and toughness) even at very high operating temperatures. It is the most widely used technical construction material, which with fillers, for. As glass fiber, can be improved. The biggest disadvantage in additive manufacturing lies in the high delay. This can be reduced by copolymers.
The amorphous thermoplastic PC (polycarbonate) has very interesting properties for various industrial applications. PC is characterized by high strength, impact resistance, rigidity and hardness. In addition, polycarbonate is a good electrical insulator. Common applications are therefore housing electronic devices and due to the mechanical properties used for small series parts and spare parts.
PVA (Soluble support)
PVA, often abbreviated to PVAL or PVOH, is a polyvinyl alcohol and water-soluble, making it very well suited for solubility support. HAGE3D uses Helios Support (Formfutura), which was developed for high temperatures as a support material in combination with standard and technical plastics. Helios support can be printed at nozzle temperatures up to 250 ° C without the risk of cross-linking and clogging the nozzles.
