High-speed 3D printer specs compared: speed, acceleration, flow

A high-speed 3D printer is one whose maker claims a top speed of at least 500 mm/s and acceleration of at least 20,000 mm/s², the thresholds set out in the speed claims guide. Of the 58 shipping printers in the database, 37 meet both.

The table sorts every shipping printer by claimed acceleration, highest first, because acceleration decides how much of a short move ever reaches top speed. The speed claims guide works through the math. The fastest 3D printers list orders the same printers by top speed, and the volumetric flow guide turns the flow column into a speed cap for a given line.

Every speed, acceleration and flow figure is the maker’s claim, and a dash means the maker publishes none. Prices are US launch prices for the base configuration.

The first 40 rows claim 20,000 mm/s² or more. All of them meet the definition except the Flashforge AD5X, Flashforge Creator 5 and Flashforge Creator 5 Pro, which list a print speed of 300 mm/s. The six shipping printers that publish no acceleration sort last and cannot be checked against the definition.

Which 3D printer has the highest acceleration?

Four shipping printers share the highest claimed acceleration, 40,000 mm/s²: the FLSUN S1 Pro, FLSUN V2 Max, Sovol SV08 and Sovol SV08 Max. No printer in the database claims more. The two FLSUN delta printers pair it with 1,200 mm/s, the highest top-speed claim of any shipping printer. The two Sovol CoreXY machines claim 700 mm/s.

Their other claims:

• FLSUN S1 Pro: 1,200 mm/s, 110 mm³/s, enclosed delta, $1,099.
• FLSUN V2 Max: 1,200 mm/s, 110 mm³/s, open-frame delta, no recorded launch price.
• Sovol SV08: 700 mm/s, 30 mm³/s, open-frame CoreXY, $549.
• Sovol SV08 Max: 700 mm/s, 50 mm³/s, open-frame CoreXY, $1,299.

The Sovol Zero made the same two claims, 40,000 mm/s² and 1,200 mm/s, but is discontinued.

At equal acceleration, top speed matters only on long moves. A move that starts and stops at rest must be about 12 mm long before the SV08 touches 700 mm/s (v² ÷ a). On anything shorter, the SV08 and the S1 Pro run identically. The S1 Pro needs 36 mm to reach 1,200 mm/s.

Six shipping printers claim the next figure, 30,000 mm/s²: the Creality K2 Plus, FLSUN T1 Max, FLSUN V400 Max, QIDI Max4 and the two Flashforge Creator 5 models. The other 29 high-speed printers claim 20,000 mm/s², which is also the median among the 52 shipping printers that publish an acceleration figure.

No standard defines an ultra or super high-speed printer. The top claims on shipping printers are 1,200 mm/s and 40,000 mm/s², and only the two FLSUN deltas make both.

No printer released in 2026 claims more than 30,000 mm/s². The two that claim it, the Flashforge Creator 5 models, list 300 mm/s and miss the speed threshold. The eight 2026 releases that meet the definition all claim 20,000 mm/s²: the Bambu Lab X2D, QIDI Plus5, Anycubic Kobra S1 Max, Anycubic Kobra 4, Anycubic Kobra X, Elegoo Centauri Carbon 2, Elegoo Centauri 2 and Creality K2 SE. The guide to whether new printers are faster compares claims by release year.

High acceleration shakes the frame, and the shaking prints ripples into the walls. The input shaping guide explains how printer firmware cancels them.

Which high-speed 3D printers have an enclosure?

Twenty-one of the 37 high-speed printers are enclosed: 11 have a heated chamber and 10 a passive enclosure. The fastest passive one, the FLSUN S1 Pro, claims 1,200 mm/s and 40,000 mm/s². Among heated chambers, five Bambu Lab models claim the top speed of 1,000 mm/s. The QIDI Max4 and Creality K2 Plus lead on acceleration at 30,000 mm/s².

Actively heated chamber (11):

• Bambu Lab X2D, H2S, H2D, H2C and H2D Pro: 1,000 mm/s, 20,000 mm/s², 65 °C chamber.
• QIDI Max4: 800 mm/s, 30,000 mm/s², 65 °C.
• Creality K2 Plus: 600 mm/s, 30,000 mm/s², 60 °C.
• Creality K2 Pro: 600 mm/s, 20,000 mm/s², 60 °C.
• QIDI Q2, QIDI Plus5 and Anycubic Kobra S1 Max: 600 mm/s, 20,000 mm/s², 65 °C.

Passive enclosure (10):

• FLSUN S1 Pro: 1,200 mm/s, 40,000 mm/s², rated for a 50 °C chamber.
• QIDI Q2C, Anycubic Kobra S1, Bambu Lab P2S, Creality K2, Creality K1 Max and Flashforge Adventurer 5M Pro: 600 mm/s, 20,000 mm/s².
• Elegoo Centauri Carbon, Elegoo Centauri Carbon 2 and Bambu Lab P1S: 500 mm/s, 20,000 mm/s².

None of the four printers at 40,000 mm/s² has a heated chamber, and three of them are open-frame. The chamber temperature list sorts every enclosed printer by its chamber rating.

How much does a high-speed 3D printer cost?

High-speed printers cost $259 to $3,799 at US launch. The cheapest is the Elegoo Neptune 4, an open-frame bedslinger (the bed moves front to back) claiming 500 mm/s and 20,000 mm/s². Across the 35 with a recorded price, the median is $549 and 13 cost $500 or less.

Where the price steps are, by launch price:

• $259: the definition’s minimum, 500 mm/s and 20,000 mm/s², on the Elegoo Neptune 4.
• $299: 600 mm/s on the Sovol SV06 ACE bedslinger.
• $299.99: an enclosure on the Elegoo Centauri Carbon, which Elegoo’s US store no longer lists. The next enclosed ones are the QIDI Q2C and Elegoo Centauri Carbon 2 at $399.
• $499: an actively heated chamber (65 °C) on the QIDI Q2.
• $549: 40,000 mm/s² on the Sovol SV08 and 1,000 mm/s on the FLSUN T1 Max delta.
• $649: 1,000 mm/s with a heated chamber on the Bambu Lab X2D.
• $1,099: 1,200 mm/s on the FLSUN S1 Pro. The other 1,200 mm/s printer, the FLSUN V2 Max, has no recorded launch price.

Eight high-speed printers launched above $1,000, up to the $3,799 Bambu Lab H2D Pro. Only one of them, the S1 Pro, makes a claim no printer under $1,000 matches: 1,200 mm/s. The guide to speed by launch price shows what higher prices buy instead. For budget cut-offs, see the fastest 3D printers under $500 and under $1,000.
