PLA blend is a PLA-based bio-blend of polylactic acid with a bio-copolyester. Makers sell it for prototypes, decorative models and some end-use parts, with a matte surface finish, and a maker recommends its own product for lower-temperature applications. On the H2C it prints at 190–230 °C, and most products need no heated chamber.
Thinly documented Nine products, with values from 5 makers' documents. No document describes its tensile, impact and heat deflection bars as printed, so tensile modulus (XY), tensile strength (XY), notched Charpy impact and HDT at 0.45 MPa are shown as published and not ranked against other materials. Read each figure as a few sheets' word.

Among the materials
Against PLA, PLA blend is 61 % more expensive. Against PETG, PLA blend is 2.1 times as expensive. Among the materials, PLA blend has a high density and a low price: both are in the top or bottom quarter of the materials that publish them.
PLA blend costs more than PLA, PETG and ABS and others
How does it compare with what an engineer would buy instead?
- PLA blend: its products' median and middle half
- an alternative
- lowest to highest
- each material's median (top row)
- set apart: test bar not described as printed, or no stated load
Each row is a material, each column a property: the bar is the middle half of a material's products, the tick their median, the hairline their lowest to highest; the ticks above the rows are every material's median.

PLA blend publishes no tensile strength (Z). Its tensile modulus (XY), tensile strength (XY), notched Charpy impact and HDT at 0.45 MPa state no orientation, so they are drawn as published.
Mechanical properties
As published, its products give a tensile strength of 45–55 MPa, a modulus of 3.1–5.1 GPa and an elongation at break of 2.2–14 %.

Printing on the H2C
PLA blend softens near 60 °C, below the H2C's 65 °C chamber

One temperature axis for the settings a print needs and the temperatures a part meets. A setting's shade is how many of the products whose sheets give a window accept each degree; the H2C's limit closes its row.

What makers say about printing it
Printing advice
Yes, the BigRep PRO HT is compatible with all open material system 3D printers with a heated print bed and adequate temperature extrusion capabilities (190-230°C).
BigRep PRO HT, maker's product page or guide, p. 1
Moisture sensitivity
Drying Recommendations 50°C for4 - 6 hours
BigRep HI-TEMP, data sheet, p. 1
More from makers: nozzle wear, warping and shrinkage, odour and emissions, adhesion between layers and supports and removal
Nozzle wear
Ruby or hardened nozzle recommended
Spectrum GreenyHT, data sheet, p. 1
Warping and shrinkage
Due to its low tendency to warp 3DJAKE niceBIO can also be printed without a heated bed.
3DJake niceBIO, data sheet, p. 1
Odour and emissions
Yes, it is, as long as the room has good ventilation or an air filtration system for the safety and comfort of the people using the 3D printer.
BigRep PRO HT, maker's product page or guide, p. 1
Adhesion between layers
Models printed with niceBIO feature outstanding layer adhesion and a refined matte finish.
3DJake niceBIO, maker's product page or guide, p. 1
Supports and removal
PLA is somewhat stronger and resistant to impact, while PRO HT is less brittle and many customers find support removal particularly easy.
