What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

3D Printlife wants to bring you BioPETG. An Eco-Friendly, premium quality PETG filament that will also degrade once it enters a commercial compost or an active landfill facility. 

3D Printlife is committed to reducing the environmental impact of 3D Printing. From our groundbreaking Enviro ABS, to our Eco-Friendly spooling and environmental contributions, we strive to deliver our customers premium quality filaments, while protecting the world we share.

With the dramatic cuts to the EPA's funding it is incumbent upon all of us to do whatever we can to protect the environment, and to set an example for our children.  With that in mind we have created new pledge levels that allow backers to donate spools of our groundbreaking BioPETG to schools around the world.  It is more important than ever to teach students everywhere that they can have it all when it comes to 3d printing with materials that are both premium grade AND eco-friendly.

Once we are funded BioPETG will be ready to ship just in time for the 2018 school year!

PETG (also called copolyester) is a modified version of PET. The added glycol prevents the material from crystallizing and becoming breakable making it an excellent material for 3d printing.

PETG is the most commonly used plastic in the world and it is one of the easiest to recycle, but it isn't biodegradable. We have long wanted to produce a premium line of PETG filament, but only if we could upgrade it by making it more eco-friendly.

Now with the addition of the same bio-additive technology used in our Enviro ABS, BioPETG is the first PETG filament that will degrade once it enters a commercial compost or landfill to energy facility. 

How does it work?

BioBETG works by combining standard PETG with a proprietary, biologically based additive. This additive is specially formulated to bond with PETG and provide a food source for the bacteria found in both commercial composts and landfill to energy facilities.

ASTM D5338-15 Environmental Testing

We tested BioPETG under ASTM D5338-15, which provides a means for determining the degree and rate of aerobic biodegradation of plastic materials when exposed to a controlled environment under laboratory conditions.

Composting Apparatus
Composting Apparatus

Samples of PETG and BioPETG were placed in 2.0-liter glass composting vessels. Each vessel was stoppered and placed in controlled water baths. Percent (%) Carbon Dioxide and % Oxygen were measured via direct gas analysis with a Quantek Instruments Model 902D Dual Trak Oxygen/Carbon Dioxide Analyzer. Direct analysis was executed via needle probe inserted into a gas collection bag. Mass loss was measured gravimetrically via a Denver Summit electronic analytical and precision balance.


The percentage of biodegradability is obtained by determining the percentage of carbon in the test material that is converted to carbon dioxide (CO2).

CO2 Production: ASTM D5338-15 PETG vs. BioPETG
CO2 Production: ASTM D5338-15 PETG vs. BioPETG

As indicated in the Table above, by day 45 BioPETG continues to produce CO2, while the PETG without the proprietary bio-additive shows expected diminished CO2 production.  

Just as a shark might try to take a bite out of a boat to test it as a food source, the bacteria in a commercial compost or active landfill leachate will attempt to consume standard thermoplastics like ABS and PETG.  After a short period however the bacteria looses interest and moves on. Conversely with BioPETG, bacterial consumption remains steady throughout the 45 day test.

Will my prints degrade on my countertop?

The bacteria content needed to consume BioPETG is exceedingly high and primarily found only in the above mentioned environments. These are some of the most foul conditions imaginable, so unless you're a Ninja Turtle living in the sewers, your BioPETG prints will maintain their structural integrity and appearance just as any premium standard PETG would.

So why print with PETG?

PETG combines many of the benefits of ABS with the ease of printing associated with PLA in one material.

Some benefits & characteristics of PETG:

  • HIgh impact resistance
  • High strength and durability
  • Excellent layer adhesion
  • Great pliability
  • Very low shrinkage (therefore little to no warping)
  • Ideal for large prints
  • Heated bed not required (though it can be helpful)
  • Smooth finish
  • High temperature resistance
  • Excellent chemical and water resistance
  • Odorless printing
  • Excellent geometric accuracy
  • Strong but flexible (ideal for drones, mechanical parts, & robotics)
  • Can be sterilized
  • FDA compliant

Obviously there are a lot of benefits to printing with PETG!  With your help BioPETG will be the world's first eco-friendly PETG filament, made in the USA to the strictest standards available on our eco-friendly spooling.

How to print with BioPETG

As with all materials there is a settings "sweet spot" that will vary from one printer to another. BioPETG is no different, but once you're dialed in printing with BioPETG is a dream.  Here are some general setting guidelines:

  • Set your nozzle temperature between 235°C and 250°C.
  • Print with cooling fan at 100%
  • A heated bed is not required but start between 70°C - 80°C if available.
  • Set print speed around 55mm/sec or less.
  • Try starting with an additional .2mm gap in the Z axis to avoid skimming.

More about 3D Printlife:

Eco-Friendly Packaging

Every spool of 3D Printlife filament comes in a durable, resealable bag with a desiccant, a thank you card indicating our donation to environmental charity to plant a tree, as well as a seed paper card to plant and grow your own wildflowers. 

Eco-Friendly Spooling & Packaging
Eco-Friendly Spooling & Packaging

3D Printlife's filament spool is made of heavy 100% recycled cardboard that is biodegradable and bound together with a recyclable tin cap. The spool includes both a cutout for viewing filament and dual puncture slots to secure filament when not in use. The flange can even rotate in either direction to aid in securing the filament wherever it has been cut. The spool was specifically designed for universal fit with most 3d printers in use worldwide.

Premium USA Manufacturing

3D Printlife filaments are made in the USA with the highest quality materials and extrusion processes available. They are manufactured using a specially designed extruder screw that is designed to promote mixing while minimizing shear and degradation of the polymers. The extrusion process is carefully controlled to promote six sigma dimensional stability of the filaments, leading to consistent printing and the elimination of clogged print heads.

Every inch of 3D Printlife filament is measured to ensure that it is within the strictest standards for quality, diameter, and ovality. The extrusion process is continuously monitored with twin axis lasers that monitor the consistency of the diameter and roundness of the filaments and deliver a dimensional accuracy better than +/- 0.03mm

3D Printlife uses only high quality 100% virgin resins and colorants in filament manufacturing. Materials are dried to remove moisture under our internal specifications. Excessive moisture in the filaments during extrusion can damage the polymer resulting in weaker polymer chains that lead to brittle filaments that can snap as they unwind from the spool or result in excessive nozzle drool.

Every spool of 3D Printlife filament is carefully wound to exacting standards to minimizing cross overs and loopbacks that can lead to snags and snaps. The filament clings tightly to the spool until it is paid off the spool, making it easy to feed into the printer reducing failed prints. We reject any spool that does not meet our exacting quality standards.

Industry Partnerships


XYZPrinting and 3D Printlife
XYZPrinting and 3D Printlife

XYZPrinting released the da Vinci 1.0 Pro in late 2015, the first XYZ printer to accept third-party filaments.  After 400 hours of testing at Florida Institute of Technology's DSL Lab, XYZPrinting named 3D Printlife's Enviro ABS as the first 3rd party filament approved for use in their printers.

“This partnership reflects a future outlook in delivering environmentally responsible, open source 3D printing solutions without sacrificing quality materials,” said Simon Shen, CEO of XYZprinting and parent company New Kinpo Group.

Free Shipping

We are providing FREE SHIPPING to all domestic backers!

Due to the high cost of international shipping we are including a shipping charge for backers outside the US.  If you are an international backer with friends or family in the US we can ship your reward to them so you can explore your own shipping options.

Shipments will not require a signature so you may want to choose an office or work address if possible.

How your contribution will be spent

Bio-Additive: In order to produce the BioPETG bio-additive cost effectively we need to produce at least 200lbs at a time.  The process is not difficult but it is still expensive.

Silk Screens & Print Plate: The spool graphics are already designed but we need to order the silk screens used to print onto the cardboard spools.  We'll also need a new print plate for the product boxes.

BioPETG Spool Design
BioPETG Spool Design

Raw Materials & Extrusion: Finally we need to purchase the virgin PETG resin and colorants, and then pay for the extrusion run of a full color BioPETG line.  Our goal is to produce 12 to 18 colors of BioPETG in both 1.75mm and 2.85mm

Coming Soon

In addition to our Enviro ABS, PLAyPHAb PLA/PHA, and BioPETG Kickstarter offering, here are some of the materials we have planned for launch through 2018:

  • Biodegradable semi-flexible filament
  • Biodegradable full flex filament
  • Biodegradable high strength engineering grade polyester

Our Current Offerings

Enviro ABS

After years of testing and development with a chemist specializing in bio-plastics, we released Enviro ABS in the fall of 2015.  Unlike every other ABS on the market, 3D Printlife's Enviro ABS is specially formulated to be consumed by bacteria once it enters a landfill to energy facility or a commercial compost. Enviro maintains the strength, heat resistance, printing characteristics, and post process capability of ABS in every way.
