Ingeo 3D860, NatureWorks’ new sustainable formulation for PLA filament, promises high impact durablity and heat resistance typically synonymous with ABS, combined with the ease of 3D printing for which PLA is known. The filament formulation was announced at present at the ‘Innovation Takes Root’ forum.

Whilst most 3D printing innovators are constantly seeking new materials with which they can 3D print, others just appear to make built 3D printing materials as great as they can probably be. NatureWorks is no conservative when it comes to materials experimentation, but its latest 3D printing filament formulation, Ingeo 3D860, appears to breathe new life into an built filament classic: PLA.
Last year, Earth-friendly materials specialist NatureWorks launched its 3D850 grade PLA, with the 3D860 assembling on the good results of which earlier formulation. According to the Blair, Nebraska-based company, the latest Ingeo formulation can, like its predecessors, contribute consumers a practical, safe, and cost effective alternative to mainstream styrenics such as ABS.
Outside of the scientific community, ABS is maybe most known as the material out of which which LEGO bricks are turn it intod. Within the 3D printing industry, yet, ABS remains a divisive material. Many 3D printing businesses favor the material over PLA for its magnificent durablity and heat resistance—properties which make it additional suitable than PLA for significant applications.
Despite its desirable material properties, ABS can cause greater environmental problems than PLA, which is biodegradable. NatureWorks seeks to promote green plastics use, by manufacturing its PLA formulations of entirely effortless sources, encouraging responsible use, and—mostly importantly—by creating a product which rivals its alternatives in material high end.
The environmental advantages afforded by NatureWorks 3D printing filament do not, of course, preclude their 3D printing high end. On the other hand, the new Ingeo 3D860 has been engineered to rival ABS in terms of impact and heat performance, and can be depended upon for the 3D printing (and injection molding) of durable parts. To unlock the ABS-level durablity and heat resistance for 3D printing applications, NatureWorks recommends a brief 10-15 minute period of annealing at temperatures between 212 and 239ºF (100 and 115ºC).
Each Ingeo formulation makes use of dextrose sugar discovered in plants. The carbon and other elements in dextrose sugar are utilized to make a biopolymer through fermentation and separation. With a greater focus now placed on green and renewable methods of production, NatureWorks sees this system as the key selling point for its products. “Many brands desire a bio-based, low carbon footprint alternative to styrenics,” said Dan Sawyer, Global Leader, New Business Segment, NatureWorks. “With the addition of Ingeo 3D860, we are providing an version which now empowers users to turn it into functional industrial parts or finished greats.”

NatureWorks has been striving to create environmentally friendly plastics since its inception in 1989, but its focus on 3D printing materials is a relatively new endeavor. In its undertaking to breach the 3D printing market, the company built a three-pronged approach, consisting of the introduction of 3D printing device-specific Ingeo grades; a full suite of technical assist services for 3D printing customers; and the creation of an in-house print lab, created to enable the swift and efficient testing of new 3D printing materials, at its Blair headquarters.
The new PLA 3D printing filament formulation was announced at present at the Innovation Takes Root forum, built by NatureWorks to connect and inform Ingeo users, in Orlando, Florida. The forum continues until April 1. The Ingeo 3D860 formulation has been demonstrated by filament supplier 3Dom, which has utilized the grade for a new filament. According to NatureWorks, 3Dom and other suppliers have responded unquestionably to the new formulation.
“We’ve had positive feedback of a few industrial users which now view this as a viable alternative to ABS for a few of their production jigs and fixtures,” Sawyer explained. “3D860 in addition allows for for rapid prototyping with the competence to approximate the physical properties achievable in injection molded parts turn it intod with ABS or with one of our Ingeo durables formulations.”
