3D printing with plastic pellets offers important benefits and advantages that are not available with current filament offerings:
- They are readily available in hundreds of new materials. This opens the door to a whole spectrum of new and interesting materials, each with their own unique properties. Some are rigid and incredibly durable, others are soft to the touch and extremely flexible. The result is the ability to print with greater flexibility.
- Plastic pellets are easy to use with the Sculptify 3D printer. If you can load a coffee maker, you can print with pellets in the Sculptify 3D printer. Pellets are loaded into the top, and ready to print in no time.
- They are the most cost effective form of plastic. Since pellets do not need to be optimized for a spool, multiple manufacturing and engineering steps can be removed. This saves a lot money, and the cost savings can be passed directly to the customer.
- ABS, Acrylonitrile butadiene styrene. Hard plastic commonly used in plastic car components and household items.
- HDPE, High-density polyethylene. Semi-hard and durable plastic, used in milk jugs and plastic bags.
- PLA, Polylactide. Hard plastic, biodegradable, made from renewable resources. The standard in 3D printing.
- EVA, Ethylene vinyl acetate. Soft silicone-like material often used in shoes and sportswear.
- Nylon. Hard and durable material that is often used in low-friction applications like bearings.
- TPU, Thermoplastic polyurethane.
- Rubber-like material that is often used in shoes and mobile device cases.
- HIPS, High impact polystyrene. Semi-hard and durable plastic used in disposable utensils and containers.
- PC, Polycarbonate. Very hard plastic that is typically transparent. Often used in safety glasses and DVDs.
- Wood composites. Earthy look and finish, often used in synthetic decking
