# PETG Polyethylene Terephthalate Glycol ## Material Info ### About PETG is a durable and easy-to-print 3D printing filament that combines excellent strength, and flexibility. Ideal for functional prototypes and everyday projects requiring durability and a clean finish, whether used indoors or outdoors, it offers superior layer adhesion and a smooth surface finish. A wide variety of colors is available and can be printed at request through [our Sales team.](/content/business/additive-manufacturing#contactsales/index.html) Parts are oriented by our team to balance strength, surface finish, and minimal supports. Final orientation is chosen for the best overall result. ### Color & Finishes White Black Custom [Contact Sales](/content/business/additive-manufacturing#contactsales/index.html) Order minimum $300 per color. **Print Mode - Light** Prints with 0.8mm Shell thickness and 15% Infill **Print Mode - Medium** Prints with 1.2mm Shell thickness and 35% Infill **Print Mode - Strong** Prints with 1.6mm Shell thickness and 75% Infill **Print Mode - Solid** Prints fully solid models ### Technology - Fused Deposition Modeling (FDM) [FDM PETG Technical Datasheet](/content/wp-content/uploads/2025/01/FDM-PETG-Technical-Datasheet.pdf) [FDM PETG SDS](/content/wp-content/uploads/2025/01/FDM-PETG-SDS.pdf) ### Material Properties - **Tensile modulus (ISO 527)** 2116.8 ± 68.1 MPa (XY), 1898.7 ± 98.5 MPa (Z) - **Tensile strength (ISO 527)** 50.8 ± 0.9 MPa (XY), 42.8 ± 2.8 MPa (Z) - **Elongation at break (ISO 527)** 8.4 ± 1.7% (XY), 3.3 ± 0.2 % (Z) - **Flexural modulus (ISO 178)** 1898.5 ± 35.5 MPa ### Description **Superior Impact Resistance** PETG boasts exceptional impact resistance compared to other thermoplastics, making it the go-to choice for products requiring durability and toughness **Recyclable & Environmentally Friendly** PETG is recyclable, supporting sustainable production practices and waste reduction efforts, making it an eco-conscious choice for manufacturers ## Design Guidelines ### Bounding Box **Maximum Bounding Box** 500x500x500 mm _Please note that parts exceeding 300 mm in any dimension will incur additional costs._ **Minimum Bounding Box** 10 x 10 x 1 mm The bounding box is a 3D imaginary outline of a box that encloses the smallest area occupied by your model. Your model must be within the minimum and maximum bounding box sizes. If the size of the model is close to the maximum bounding box, then the printing orientation will be restricted. ### Walls **Supported Walls** 0.8 mm **Unsupported Walls** 1 mm A supported wall is connected at least on two sides of the wall, while an unsupported wall is connected only on one side of the wall. Walls that do not meet the minimum requirements may not survive printing and cleaning processes. Additionally, models may still be rejected based on the wall geometry of the model. Please consider the size of your model and reinforce the walls or add support structures as needed as minimum guidelines will not always be adequate for large models. ### Wires **Supported Wires** 1.5 mm **Unsupported Wires** 1.5 mm A wire is a circular, rectangular or even triangular feature that is thinner in its unconnected directions than its length. A supported wire is connected at least on two sides of the model, while an unsupported wire is connected on one side of the model. Wires that do not meet the minimum requirements may not survive printing and cleaning processes. Additionally, models may still be rejected based on the wire geometry of the model. Please consider the size of your model and reinforce the wires or add support structures as needed as minimum guidelines will not always be adequate for large models. ### Details **Embossed Details** 0.2 mm **Engraved Details** 0.2 mm For text, the ratio between width and depth, should be 1:1 and sans-serif fonts are preferred for line weight consistency. ### Clearance **Minimum** 0.50 mm _loose fit_ 0.40 mm _normal fit_ 0.25 mm _tight fit_ Clearance is the space between two individual parts in a model. If the space among the individual parts do not meet the minimum clearance, then parts can fuse together or can be difficult to clean. This is important for movable pieces like hinges, gears, etc. ### Sprues **Not supported** Sprues are wires that keep two or more parts together. Parts should be connected with a minimum of two sprues each. Please consider the size of your sprues and increase them as needed as minimum guidelines will not always be adequate for large models. If the sprues are within the guidelines and are broken, but there is no damage to your model, we will still ship them as is. ### Interlocking & Enclosed Parts **Interlocking** Supported **Enclosed** Not supported ### Multiple Parts Supported ### Accuracy ±0.1 mm to ±0.3 mm ## Related Materials **Acrylonitrile Styrene Acrylate** **Application:** A high-performance, weather-resistant thermoplastic ideal for outdoor applications.
