TPU 95A class is thermoplastic polyurethane, a flexible elastomer. Makers sell it for phone cases, insoles and functional parts. Its tensile modulus (XY) is 0.027 GPa, and printed across the layers it keeps 81 % of its flat tensile strength. On the H2C it needs no heated chamber, and nearly every product calls for drying.
Partly documented Notched Charpy impact rests on 1 product and price on 2 products. Each figure is the median of the products that publish it comparably, and beside it the middle half of them; a value on a test bar no document describes as printed, or with no stated test load, is set apart, except a heat deflection of a plastic that cannot crystallise, which its glass transition sets, unless its document points to a moulded or resin bar.

Among the materials
Against TPU-CF, TPU 95A class is 56 % less expensive. Against TPU 85A class and softer, TPU 95A class is 2.7 times as strong across the layers, 2.1 times as stiff and 43 % more expensive. Among the materials, TPU 95A class has a high elongation at break (XY) and notched Charpy impact, and a low tensile modulus (XY) and tensile strength (XY): each is in the top or bottom quarter of the materials that publish it. The rest of its key properties sit in the middle half.
Against its alternatives, TPU 95A class has the highest tensile strength and tensile strength (Z)
How does it compare with what an engineer would buy instead?

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.

Where a product's own sheet is silent, its setting comes from a sheet it shares or from the Bambu Lab Filament Guide; each product's card says which. The guide has no column named TPU 95A class; its TPU 95A HF column is shown. Bambu Lab rates TPU 95A HF 95A, in the 93 to 97A class. Not the other hardness classes, TPU-CF, -GF, -LW, -EC, -ESD, TPE, TPS or TPC.
After printing
One product publishes values measured after annealing, at 70 °C for 12 h.
It's not recommended to anneal prints of TPU, or prints with not very simple shape and structure can deform obviously.

What makers say about printing it
Printing advice
Proper drying of the material and increased retraction distance are required to minimize stringing.

Makers rarely give the concentration, temperature or duration: treat them as indications, not design data. Each product's statements are on its card.
Resin reference data (for plain TPU, where no maker of these products speaks): it needs stabilising against UV radiation. Fillers, pigments and printing change this, so it does not stand for these products.
Density and price
TPU 95A class's density is typically 1,210 kg/m³, the middle half 1,160–1,220 kg/m³, across 25 products. TPU 95A class typically costs 83 CAD/kg, across the 2 products with a regular price in the sample; the lowest is Bambu Lab TPU 95A HF at 54 CAD/kg.
