rPLA Flake

Polylactic Acid, more commonly known as PLA, is one of the most frequently used materials in 3D printing. Its popularity comes from its ease of use, organic nature, and relatively strong mechanical properties. PLA is also inexpensive making it a great entry-level material. PLA also boasts strong mechanical properties and user-friendly thermal properties that make it easy to print with. Its prevalence and ease of use makes it a perfect material to regrind and recycle. For those who prototype often, rPLA is a sustainable solution.

rPLA is a great material for applications that require rapid prototyping and strong parts. Its ease of use and low cost make it suitable when a part may be frequently reprinted as is the case in prototyping and architecture. rPLA is easily recycled, proving to be a sustainable solution for rapid prototyping. Its strength and ease of use make it suitable for those who need to turn over a lot of strong, functional prototypes.

rPLA is created by grinding failed or older PLA prints. Much like normal PLA, rPLA is made from organic sources and is thus compostable. Since PLA is difficult to recycle at commercial recycling centers, regrinding PLA into rPLA and reusing it in pellet printers is a more sustainable alternative.

rPET Pellets

Polyethylene Terephthalate (PET) is a durable material with either a glossy appearance or opaque appearance depending on its crystallinity. PET is one of the most common plastics in the world, used in cases like sailcloth, water bottles, and clothes. In the world of 3D printing, PET is often used in the form of PETG which contains glycol. PET and PETG fill a role between PLA and ABS being a tough material and relatively easy to work with. With the rise of pellet printing, PET is growing in relevance as a 3D printing material. PET is also one of the most commonly recycled plastics, making its potential use in 3D printing even more attractive. For those looking for durable parts and a closed loop 3D printing solution, PET is a great material to use.

PET excels when you take advantage of its material properties and its prevalence. Its material properties allow it to perform well in a variety of applications. Its prevalence also makes it a great candidate for recycling and closed loop use cases.

PET is one of the most commonly used recyclable plastics, and often seen in the form of water bottles. The polymer chains that make up PET easily break apart at low temperatures, making PET an easy material to recycle. Being such a common material, there is great potential of recycling and reusing PET. One area of potential use is recycling PET as feedstock for pellet printers like Gigabot X. PET is easily recycled in most recycling centers, and an excellent choice for closed loop solutions due to its prevalence.

PC

Polycarbonate (PC) is a high performance material intended for use in engineering and industrial settings. As suggested by its name, PC contains carbonate groups that contribute significantly to its strength and toughness. PC also has excellent temperature resistance, making it useful in high temperature applications as well. Its strength, toughness, and temperature resistance makes it a useful material for final production or industrial parts. PC is also useful with electronics since it is an insulator.

PC’s high performing properties make it a good choice for industrial applications. Parts made from PC can withstand the demanding environment found in industry. PC is also a good choice for storage, especially electronic enclosures. Since PC does not conduct electricity, sensitive electronics will remain safe in PC enclosures. Many of the parts on re:3D Gigabot printers is made with PC. Finally, PC is perfect for any parts that needs to resist high temperatures.

Polycarbonate is recycled most often into a reground material. This material is often considered for use in a pellet extrusion machine such as GBX. Polycarbonate is not usually supported by recycling centers since it is grouped into resin code 7 with “other plastics”. Polycarbonate also risks producing bisphenol A, commonly known as BPA.

3D Scanning

We are now capable of capturing high quality 3D scans of objects up to 13 feet in length. The scans can be made into a 3D printable model or used for reverse engineering. Produced model is only able to capture the geometry of the part, not color. Scans can be done both in house and on site depending on the size of the part. The scanner used: Creaform HandySCAN BLACK^TM Elite.

Flexibles

Thermoplastic Polyurethanes (TPU) are a category of materials that feature rubber-like mechanical properties. Parts made from TPU tend to stretch and flex easily while maintaining their original shape. This unique property of TPU enables it to fulfill a variety of applications that require flexibility. Though flexible, TPU is a tough material. It features a hardness that is comparable to PETG depending on the specific TPU used. This makes it as useful in harsher industrial applications as it is in gentler environments. When flexibility is key, TPU is the best material for the job.

TPU’s flexibility is the driver for most of its applications. This flexibility comes into great use in footwear where a cushion is needed for a shoe’s sole. Wheels and tires are another example where TPU’s flexibility shines. TPU is a good choice for phone cases and handles by providing a softer grip and a dampening effect. In industrial uses, TPU excels for grommets and dampers where traditional rubber is too weak. TPU’s hardness and flexibility enable dampers and grommets to endure for a long time.

TPU recycling does exist, but the ability to recycle 3D printed TPU parts remains uninvestigated. Usually TPU recycling involves breaking down a specific TPU product and reusing its material in the same application it came from. For example, polyurethane foam from mattresses tends to be recycled into new mattresses.
