Shore hardnessWhat the number on the spool actually feels like
Soft as a car tyre→stiff as PLAShore A softer scale
Shore D harder scale
85A
About as firm as a shoe soleThis roll is 95A
Softest we stock.
Stretches a long way and springs straight back. Squash it in your hand and it gives easily.
Good forSoft grips, vibration pads, squishy toys, cosplay parts
PrintingThe fussiest of the lot. Go slow and use a direct drive extruder.
90A
About as firm as a rubber doorstopThis roll is 95A
Very flexible.
Bends without much effort and holds its shape when you let go.
Good forDrone bumpers, watch straps, seals, soft grips
PrintingStill soft. Slow it down and keep the filament path short.
95A
About as firm as a phone caseThis roll
The standard TPU.
The one most people mean when they say TPU. Properly flexible, still easy enough to print.
Good forPhone cases, gaskets, living hinges, RC tyres, protective covers
PrintingPrints on most machines, Bowden included, as long as you slow down.
98A
About as firm as an office chair wheelThis roll is 95A
Firm flex.
You can bend it, but you have to mean it. Barely stretches at all.
Good forTool grips, bushings, heavy duty wheels, impact parts
PrintingThe easiest of the A grades. Close to a normal filament.
64D
About as firm as a golf ballThis roll is 95A
Semi rigid.
Thin walls still flex. Anything chunky feels solid in the hand.
Good forSnap fits, tough enclosures, wear pads
PrintingPrints much like PETG. Dry it first.
68D
About as firm as a hard hatThis roll is 95A
Stiff.
Feels like a plastic part with a bit of give left in it.
Good forGears, bumpers, cases that get dropped
PrintingPrints much like PETG. Dry it first.
70D
About as firm as a chopping boardThis roll is 95A
Rigid.
Stiff enough that you would not call it rubbery any more.
Good forStructural parts that still need to take a knock
PrintingPrints much like PETG. Dry it first.
75D
About as firm as a Lego brickThis roll is 95A
Nearly rigid.
About as stiff as normal printed plastic, just far tougher. It dents instead of shattering.
Good forImpact resistant brackets, tough functional parts
PrintingPrints much like PETG. Dry it first.
Print Settings
Hotend210-230°C
This temp range may not match what is printed on the spool. With the wide variety of 3D printers and platforms out there, branded machines often print at slightly different temps — some run hotter, some cooler. I have built slicer profiles for the popular printers (see the Slicer Profiles button below); if yours is not covered, use your printer’s generic temp for this material family as a starting point and tune from there. Trust the value here for the most accurate range — the site is updated as I learn from each batch.
Heated Bed50-60°C
EnclosureNot Required
“Enclosure” = a closed chamber that holds heat — not just walls around your printer. The chamber needs to actually get warm (passively from the bed, or actively heated) so the print stays at a consistent temperature and doesn’t warp or split between layers.
Examples of enclosed printers: Bambu X1C / P1S, Prusa CORE One, Voron 2.4 / Trident, Qidi X-Plus, anything with sealed doors and a hot chamber.
Examples of open printers: Bambu A1 / A1 mini, Prusa MK4 / MINI, Ender 3, most bedslingers. These are fine for PLA / PETG / TPU / PVA but struggle with materials marked “Required” on this row — ABS, ASA, PC, Nylon and similar will warp or delaminate without a hot chamber.

Hardened NozzleNot Required
A hardened steel (or ruby / tungsten / diamond-tipped) nozzle is recommended for any abrasive filament — carbon-fibre, glass-fibre, sparkle/glitter, glow-in-the-dark, marble, wood, metal-filled, etc. Brass nozzles wear out quickly with these materials and the bore enlarges, ruining flow accuracy. For plain PLA, PETG, ABS, ASA, TPU, PVA, PC and other non-abrasive blends, a stock brass nozzle is fine.
Drying45-55°C / 4-6 hours
Although the value above is the textbook drying recommendation for this material, Sidd’s rule is: dry every roll for at least 12 hours, at a minimum of 50 °C and around 70 °C on average*. If you’re drying multiple materials in the same dryer, average them out and lean towards 70 °C — it’s safe for everything we sell and gives the most consistent print results.
* Depends on your dryer. If you’ve got a strong dryer (Sunlu S2/S4, PrintDry Pro, Eibos, etc.) 55 °C max is plenty. If your dryer is a weak boi (basic food dehydrator, cheap clip-on, fan-only) push it to 70 °C to actually move moisture out.

Material
HDT (typical)~60°C
Length~310 m
Density1.09 g/cm³
Diameter1.75 mm
Colour StabilityStable
I always aim for the same colour across batches, but with the huge range of materials I produce, a slight variation between batches is bound to happen eventually. It’s rare, but it can occur. If a batch is noticeably different it gets sold off as clearance stock rather than mixed in with the standard range.
