Sovol SV08 filament needs to keep up with a printer built for speed: a 350x350x345mm bed, a dual-gear direct drive extruder, and print speeds up to 700mm/s. Most filament sold for "SV08" online is actually written for the larger SV08 Max, a different machine. Siraya Tech stocks PLA, PETG, PETG-CF, and TPU formulated for the standard SV08's real specs.
What Works on the Standard SV08
The standard Sovol SV08, not the Max, has a 350x350x345mm build volume, a hotend rated to 300C, a bed rated to 100C, and a 0.4mm nozzle with 0.2/0.6/0.8mm sizes available. Sovol officially supports PLA, PETG, TPU, PETG-CF, and ABS. The frame is open by default, with an optional enclosure sold separately for ABS and other heat sensitive prints.
PLA and PETG print well at the SV08's default speeds with no changes needed
PETG-CF needs a hardened steel nozzle before printing
TPU benefits from the dual-gear direct drive extruder already built into the SV08
ABS prints best with the optional enclosure installed

Why High Speed Filament Matters Here
The SV08's 700mm/s top speed and Klipper firmware are only useful if the filament can flow fast enough to keep up. Standard PLA and PETG can struggle to melt and extrude quickly enough at very high speeds, leading to under extrusion. High flow formulations are built specifically to keep pace with printers like the SV08 without sacrificing layer adhesion, which matters more here than on a printer with a lower speed ceiling.
How to Print PETG-CF Successfully on the SV08
Install a hardened steel nozzle first. Carbon fiber filament wears through brass and stock stainless nozzles quickly.
Dry the filament before printing. PETG-CF absorbs moisture, and wet filament strings and weakens layer bonding.
Take advantage of the dual-gear direct drive extruder, which feeds stiffer fiber filled filament more consistently than a Bowden setup would.
Keep speeds moderate on fiber filled filament even though the SV08 can run much faster, since CF filaments benefit from controlled extrusion over raw speed.
Use an enclosure for ABS prints. The SV08 ships open frame, and ABS needs stable ambient heat to avoid warping.
PLA, PETG, PETG-CF, TPU, and ABS are all officially supported on the standard SV08. High speed or high flow formulations of PLA and PETG are worth choosing specifically because the SV08 can print at speeds up to 700mm/s, and standard filament can underperform at that pace.
Is the SV08 the same as the SV08 Max?
No. The standard SV08 has a 350x350x345mm build volume, while the SV08 Max is a larger machine at 500x500x500mm. Much of the content found online for "SV08 filament" is actually written for the Max, so it pays to confirm specs match the standard model before relying on someone else's settings.
Does the SV08 need a hardened steel nozzle?
Only for carbon or glass fiber filament. The stock 0.4mm nozzle handles PLA, PETG, TPU, and ABS without issue, but fiber reinforced filament will wear through it and needs a hardened steel nozzle instead.
Can I print ABS on the SV08 without an enclosure?
You can, but results improve significantly with one. The SV08 ships as an open frame printer, and ABS is prone to warping without stable ambient heat. Sovol sells an optional enclosure for this reason.
Why does print speed matter for filament choice on the SV08?
The SV08 is built to print up to 700mm/s, but standard filament formulations cannot always melt and extrude fast enough to keep up, leading to under extrusion. High speed or high flow PLA and PETG are formulated specifically to maintain layer adhesion at the speeds this printer is capable of.
