Feature-by-Feature Comparison

Let's dive into a detailed comparison of PLA and PETG across several key criteria, helping you pinpoint the best fit for your 3D-Druck project in Deutschland.

Criterion	PLA (Polylactic Acid)	PETG (Polyethylene Terephthalate Glycol)
Ease of Printing	Generally considered the easiest filament to print. Low melting point, minimal warping, and no heated bed required for smaller prints (though recommended). Odourless printing. Excellent for beginners and intricate designs.	Relatively easy to print, but slightly more challenging than PLA. Requires higher printing temperatures and a heated bed to prevent warping and ensure good bed adhesion. Can be prone to stringing if retraction settings aren't dialled in.
Strength & Durability	Good tensile strength but brittle. Parts can snap under stress. Not ideal for functional components that experience impact or flexing. Best for models, prototypes, and aesthetic items.	Excellent tensile strength, significantly more durable and impact-resistant than PLA. Offers good flexibility, allowing parts to bend before breaking. Ideal for functional parts, tools, and mechanical components.
Temperature Resistance	Low heat deflection temperature, typically deforming at around 60°C. Not suitable for parts exposed to high temperatures, direct sunlight, or hot environments (e.g., car interiors).	High heat resistance, typically with a glass transition temperature around 80-90°C. Can withstand hotter environments than PLA, making it suitable for outdoor use or components near heat sources.
Flexibility	Rigid and stiff. Offers very little flexibility before fracturing. Not suitable for parts that require any degree of bend or resilience.	Good inherent flexibility and ductility. Parts can absorb impact and flex without immediate breakage. This makes it ideal for 3d-druck teile online bestellen for applications needing a bit of give, like clips or protective covers.
Post-Processing	Easy to sand, paint, and glue. Can be tricky to vapor smooth. Best for finishing with traditional methods. Good for models requiring a smooth, painted finish.	Can be challenging to sand due to its tough, slightly flexible nature. Resists most solvents, making vapor smoothing difficult. Typically used for functional parts where surface finish is less critical, or parts that benefit from its natural sheen.
Environmental Impact	Derived from renewable resources (e.g., corn starch) and is biodegradable under industrial composting conditions. A more environmentally friendly choice for disposable or short-term prototypes.	Not biodegradable, but recyclable (though often requires specific facilities, similar to PET plastic bottles). Made from petroleum-based resources. Less eco-friendly than PLA in terms of disposal, but its durability can lead to longer-lasting prints.
Adhesion (Layer & Bed)	Excellent layer adhesion, creating strong bonds between layers. Good bed adhesion with a wide range of surfaces, often without needing adhesives, reducing the chance of failed prints.	Very good layer adhesion, often resulting in strong, robust parts. Strong bed adhesion can sometimes be too strong, potentially damaging the print surface if not handled carefully. Use of an interface like painter's tape or glue stick is often recommended.
Chemical Resistance	Relatively poor chemical resistance. Soluble in some strong solvents like chloroform. Not ideal for parts that will be in contact with harsh chemicals.	Good chemical resistance to water, acids, and alkalis. This makes it a better choice for containers or parts that might be exposed to various liquids.
