ProPLA takes the good qualities of PLA and improves the temperature resistance and impact resistance (through post-print annealing). Our filament is made in the USA from only virgin raw materials. Triple-axis diameter measurements are taken on the production line and shared with you, so you know exactly what you're getting.
Veracity (ve·rac·i·ty) (noun)
1.) habitual observance of truth in speech or statement; truthfulness:
2.) accuracy: to question the veracity of his account.
3.) correctness or accuracy, as of the senses or of a scientific instrument.
In short, we have named this filament Veracity as we have taken a very open approach: from disclosing the specific resin used to sharing the exact production line data on a per spool basis, we're valuing truth, openness, and accuracy.
Made in the USA, in Barberton Ohio by Keene Village Plastics (KVP). As a plastic extrusion company with over a decade of experience extruding 3D printer filaments, KVP has a serious committment to quality. Knowing you can trust who makes your filament is important, which is why we’re not rebranding or white labeling this filament. KVP is the original supplier to many companies including Makerbot, 3D Systems, and Lulzbot. All of KVP's production lines (15 in a 30,000sqft new facility, processing 500,000kg annually) are tied to a central production and quality control system.
Every individual product that comes off the line gets a unique bar code that allows us to track everything about that particular reel or Koil. The data is stored for 5 years, so if anything comes up during this time we can research that specific item. The quality database stores information that includes: production date, technician, line number, settings, material and blends and colors, and up to 250,000 measurements of the filament. All of the lines are monitored in real time and any product that falls out of spec causes a series of alarms on the monitor screens and line. That product never makes it out of the facility. We use a 3 axis laser scanning system on all lines unlike most other producers that use dual axis systems.
We're sharing that filament diameter data with you. As mentioned above, every spool's filament data is measured and recorded on the production line. This data is made available to you by looking up the spool's unique serial number. Here's an example of the sort of graph you can expect:

Attention to detail. Because the little things matter.

Ingeo 3D870 is formulated to crystallize when annealed post-printing. Crystallization is a simple and effective route to improve the thermal performance and further enhance the impact properties of Ingeo 3D870. The recommended anneal temperature is in the range of 110°C-120°C. Annealing can be carried out in an oven or some other medium of heat-transfer, such as a hot- water bath. Make sure to follow safety procedures that are appropriate for working around elevated temperatures. Below is a general guideline to anneal parts printed with Ingeo 3D870:
Pre-heat oven to an anneal temperature range of (110°C-120°C).
Measure temperature at various locations in the oven to ensure absence of hot/cold spots. Uneven heating can lead
to unexpected warpage and sub-optimal performance of the part
Place printed part in oven and start timer. Typical time to anneal parts with wall-thickness of 0.125 in (~3.18 mm) is
around 20 minutes, but this time is dependent on wall thickness.
For large dimension parts, it is common to use support fixtures (e.g.-aluminum jigs) during the annealing process
Once removed from the oven, let the part cool in ambient conditions. Minimize handling, as inside of the part will
likely remain at elevated temperatures longer than the outside.
If using a water-bath to anneal, the part may have to be at temperature for a slightly longer time to crystallize (since the water-bath cannot be at 110°C-120°C).
7. Measure dimensions of the part prior to annealing and again after, to determine shrink.
