WHAT MATERIAL SHOULD I USED?

ABS

Acrylonitrile butadiene styrene (ABS) is a low-cost plastic used in injection modelling. This material has a high impact resistance, strength, and stiffness. Being exposed to weather conditions such as UV light, oxygen, moisture, heat causes aging to occur this is due because Polybutadiene stimulates the oxidation of Polystyrene. This causes discolouration and the plastic loses its mechanical strength.

Advantages

• High Impact Resistance.
• Slightly Flexible.
• Dishwasher friendly.

Disadvantages

• Made from oil, so more damaging to the environment.
• Not suitable for using with food.

ASA

Acrylonitrile-Styrene-Acrylate (ASA) has properties similar to those of ABS plastics. However, the ASA properties are far less affected by outdoor weathering. ASA parts have good chemical and heat resistance, and high impact strength, even at low temperatures. Typical ASA applications are building/construction, automotive and recreation parts.

Advantages

• Zero Warping
• Weather Resistant
• UV Resistant
• Great Layer Adhesion

Disadvantages

• Toxic Fumes when burnt

PET-G

Polyethylene terephthalate glycol modified (PETG) is the common thermoplastics of the polyester family and is used in fibres for clothing, bottles for liquids and foods. PETG is a modified PET, PETG is a clear amorphous thermoplastic

Advantages

• Strong and Smooth Finish
• Excellent Layer Adhesion
• High Transparency
• FDA Friendly
• It is more durable.
• Overheating regular PET makes it hazy and brittle, but not with PETG filament. The added glycol prevents the material from crystallizing and becoming breakable.
• It is highly impact-resistant.
• Unlike PET, it is RF sealable.
• It can be sterilized.

PLA

Polylactic acid (PLA) is the most environmentally friendly solution in the domain of 3D printing when using plastic filaments. It is biodegradable plastic coming from renewable organic resources such as corn starch or sugarcane. PLA Filament is recyclable but can also be biological decomposed in composting plants. Models will have a glossier look and feel.

Advantages

• Environmentally friendly
• Odourless
• Food contact acceptable
• Biodegradable and compostable

Disadvantages

• Can be deformed in heat
• Flammable at high heats (250°C)

HEMP

Hemp fibres are one of the oldest and strongest natural fibre. Combinding PLA with Hemp fibres these two materials together create a strong but biodegradable and compostable new material.

Advantages

• Environmentally friendly
• Odourless
• Food contact acceptable
• Biodegradable and compostable
