InfiMaker K1 on Kickstarter: True 5-Axis Desktop CNC With AI-Assisted CAM
Updated: Sep 14
A compound curve is where most desktop mills give up. Three axes reach one face at a time, so an undercut or a curved wall on the far side means unclamping, re-zeroing, and hoping the part still lines up. The InfiMaker K1 on Kickstarter is built to end that trip, moving all five axes at once instead of locking two of them into a fixed angle between cuts.
The campaign has raised $4,290,734 from 755 backers against a $49,972 goal with 12 days remaining. InfiMaker's engineers cut their teeth at DJI, and ToolGuyd reports the company has already completed first-batch production validation, with a Shenzhen factory rated for 3,000 units a month.
Quick Verdict
Our verdict: 8.9/10
Who Is It For?
The InfiMaker K1 CNC machine suits independent engineers and product designers prototyping multi-face aluminum or titanium parts that a 3-axis mill can't finish without repositioning. It also fits jewelry and watchmaking workshops cutting fine detail in brass or wax, and hardware teams that need a bracket machined the same day rather than quoted out to a shop.
Main Strengths
True simultaneous 5-axis motion (RTCP-driven) holds 0.01mm positioning, finishing an undercut or a compound angle in one clamping instead of 3+2 indexing. InfiMaker has confirmed a one-piece gray cast iron bed for the final production version, which it says cuts vibration and holds that precision over long runs.
The 1500W, 20,000 RPM spindle pairs with the optional InfiFlow coolant system, rated by InfiMaker for 30 to 50% longer tool life on titanium and steel.
InfiStudio turns a text prompt, a photo, or a CAD file into a finished toolpath with no separate CAM purchase, and the K1 also accepts G-code imported straight from Fusion 360, UG/NX, or PowerMill.
A 6-station tool changer, five tool slots plus an integrated ruby probe, switches between roughing, finishing, drilling, and tapping mid-job, with breakpoint-resume after a power cut.
InfiMaker lists eleven materials from titanium and steel to jewelry wax and jade, covering structural metal and fine jewelry work in the same spec sheet.
Main Limitations
The 20,000 RPM spindle is a third of the 60,000 RPM some rival desktop 5-axis machines publish, a constraint for small-diameter finishing cutters.
No CE, FCC, or equivalent certification is referenced in the campaign material, despite a general claim of complying with local regulations.
At around 166kg (366lb) and 560 x 700 x 800mm, buyers should confirm their bench or stand is rated for that weight before ordering, despite the "desktop" branding.
Is the InfiMaker K1 on Kickstarter Worth Backing?
Back the InfiMaker K1 if your work moves between metals and needs a fifth axis that actually machines simultaneously rather than indexing into position. Pass if your parts are flat stock or plastic only, where a 3-axis machine costs less. Backed by a DJI-trained engineering team and a factory ToolGuyd reports is already validated for production, the InfiMaker K1 on Kickstarter is the stronger buy for anyone replacing outsourced metal work in-house.
InfiMaker K1 Price on Kickstarter
The tier to back is the Super Early Bird Basic Kit at $5,199, 40% off the $8,599 MSRP, including the K1 machine, the basic material and bit kits, the wireless ruby-tip probe, and a tool kit. Anyone planning to cut titanium or stainless steel regularly should step up to the $5,799 InfiFlow Bundle instead, 37% off $9,199, since it swaps in the advanced material kit with titanium and stainless steel stock, a titanium and stainless bit set, and the InfiFlow high-pressure coolant system that is otherwise an optional $499 add-on. The $5,999 All-in-one Bundle, 36% off $9,399, builds on the InfiFlow Bundle's contents with a wireless jog handwheel and V-groove vise jaws for anyone setting up a permanent station. Backers who locked in the pre-launch $50 VIP deposit get a further $200 off whichever Super Early Bird tier they choose once the campaign closes: InfiMaker matches the deposit email to the backer's Kickstarter account, applies the discount to the pledge, and refunds the original $50 within 14 days.
For a 5-axis desktop CNC, the entry price already includes InfiStudio's AI-assisted CAM at no extra cost, and the K1 machine itself is rated to cut titanium and steel at any tier, with the InfiFlow Bundle adding the stock and the coolant system that makes that cutting routine rather than occasional. InfiMaker's own numbers make the case concrete: a red-copper cutwork ring that costs $52 outsourced runs about $8 in raw stock machined in-house, the kind of per-part math that pays back the $5,199 entry price fast for anyone cutting more than a handful of parts a year. The InfiMaker K1 Super Early Bird starts at $5,199 on Kickstarter. Our CNC machines guide covers the wider field.
What Is the InfiMaker K1 and What Problem Does It Solve?
InfiMaker K1: A True 5-Axis Desktop CNC With AI-Assisted CAM Built In
The InfiMaker K1 on Kickstarter is a five-axis CNC mill built to keep design, toolpath generation, and cutting inside one machine rather than splitting the job across separate hardware, CAM software, and a manual setup routine. All five axes move together in real time through RTCP-driven motion, rather than locking two into a fixed angle and cutting from there, which is what lets a single clamping finish faces that don't sit parallel. InfiStudio, the built-in CAM, runs the same pipeline from importing or generating a model through simulating and cutting the toolpath.
Positioning holds to 0.01mm on the X, Y, and Z axes, with rotary repeatability to 40 arcseconds on the B and C axes. InfiMaker traces the K1 to a first prototype in January 2024, with the RTCP breakthrough that makes simultaneous motion possible following two months later and the Shenzhen line coming online this July, ahead of the August launch.
Why Multi-Face Metal Parts Still Go Out the Door for Machining
Every desktop mill eventually asks the same question: which face matters most? Whichever gets clamped first machines cleanly; the rest wait for another setup, and each new clamping is one more chance for the part to drift out of alignment with the one before it. A mold cavity, a fine detail casting, or any part where faces have to line up with each other rarely survives more than a couple of those handoffs, so it usually just gets quoted out to a shop and picked up a week later.
InfiMaker builds the K1 for both halves of that problem: a spindle and frame rated for metal from the outset, not lightened down from a plastic-focused design, and CAM included rather than sourced and licensed separately. The result, per InfiMaker, is a single setup replacing the repositioning, the outside quote, and the wait, whether the part is a titanium bracket, a brass fitting, or a jewelry casting.
InfiMaker K1 Key Features and Specs: 5-Axis Motion, AI-Assisted CAM, and Multi-Material Machining
True Simultaneous 5-Axis Motion: RTCP Control at 0.01mm Repeatability
Positional five-axis machining, often sold as "3+2", rotates two axes into a fixed angle, locks them, and cuts before repositioning for the next face. The K1 keeps all five moving together instead, RTCP support keeping the tool tip on its programmed path as the rotary axes swing.
Travel spans 220 x 160 x 180mm, the B-axis runs -30 to 110 degrees, and C rotates the full 360.
Repeatability holds to 0.01mm on X, Y, and Z, with B and C at 40 arcseconds, tight enough for the fine jewelry and precision parts InfiMaker says the tolerance is built for. Automatic workpiece centering finds zero before each job, and the worktable carries loads to 15kg.
1500W InfiFlow Spindle: Titanium and Steel Without the Wait
The spindle is rated at 1500W, spinning to 20,000 RPM with a rapid feed rate of 4,500mm/min and a cutting feed rate of 2,500mm/min. InfiFlow, InfiMaker's high-pressure water coolant, is optional on the base kit and standard on the InfiFlow Bundle, rated for 30 to 50% longer tool life plus cleaner finishes and automatic coolant recycling.
Make Something's YouTube review put this InfiMaker K1 CNC machine through a hammer-head cut in oak, brass, and stainless steel using the tool changer throughout, demonstrating the spindle across materials. At 20,000 RPM, the K1 gives up spindle speed against 60,000-RPM rivals; InfiMaker doesn't publish a torque curve that would confirm this as a deliberate trade-off rather than a plain limitation.
InfiStudio AI CAM and 6-Slot Auto Tool Change: From Photo to Finished Part, Unattended
InfiStudio turns a description, a photo, or a CAD file into a finished part in three steps: import or generate the model, build and simulate the toolpath, then scan the material tag so the machine sets its own cutting parameters. Android Authority tested this directly at InfiMaker's HQ, turning a plain block of wood into a finished figurine in a few clicks with no CNC background going in. For backers who already run Fusion 360, UG/NX, or PowerMill, the K1 also accepts G-code imported straight from those tools, no post-processor required.
The tool changer holds six stations, five tool slots plus an integrated ruby probe, switching between cutting and probing mid-job, with the probe auto-locating and calibrating as part of the same flow. Breakpoint-resume machining picks a job back up after a power outage instead of restarting from zero, and an onboard camera watches for tool collisions and workpiece shifting through unattended runs.
120x120x120mm Work Volume and an Eleven-Material Range: Titanium to Wax
Five-axis work tops out at 120 x 120 x 120mm, which InfiMaker calls the largest work volume of any desktop 5-axis CNC, about 72.8% more machining space than comparable machines. 3-axis mode opens the table to 220 x 150 x 150mm for flatter stock, with 3+2 between the two at 170 x 150 x 150mm. InfiMaker has confirmed a one-piece gray cast iron bed for final production, a change over 80% of surveyed backers asked for; the company says it resists deformation under load, damps vibration for a cleaner finish, and holds tolerance better on long runs. A new bellows cover keeps chips and dust off the machine's motion areas.
InfiMaker lists titanium, steel, aluminum, brass, copper, wood, acrylic, wax, jade, resin, and engineering plastics across more than 100 applications, wax and jade included for jewelry work alongside structural metals. The bed upgrade brings net weight to around 166kg, and the machine still tests under 70dB, quiet enough for a shared workshop.
Should You Back the InfiMaker K1 on Kickstarter?
The InfiMaker K1 is the 5-axis desktop CNC for a shop that has outgrown a three-axis mill but isn't ready to rent floor space for an industrial machine.
The K1's material list settles a question its closest simultaneous five-axis rivals still leave open: titanium and steel appear outright, where TOPFAB's list has no steel at all and IFMAKER's own test documentation only covers titanium so far. A jewelry maker moving from wax carving to a finished cast piece and an engineer iterating on a titanium bracket both go from InfiStudio's model straight to a finished part, without a separate CAM seat or a trip to a machine shop in between.
InfiMaker's four specialist leads, in fixturing, precision mechanics, CAM software, and motion control, built the InfiMaker K1 CNC machine over two years before it reached Kickstarter, and the campaign is already successfully funded with 12 days left. At $5,199 for the Super Early Bird Basic Kit against an $8,599 MSRP, or $5,799 for the InfiFlow Bundle with hard-metal cooling included, the InfiMaker K1 on Kickstarter is currently funding with shipments planned for December 2026.
FAQ about the InfiMaker K1 on Kickstarter
Is the InfiMaker K1 a true 5-axis CNC, or does it only do 3+2 positioning?
True simultaneous 5-axis: all axes move together in real time rather than locking into position between cuts. InfiMaker also supports 3-axis and 3+2 for simpler jobs that don't need it.
Can the InfiMaker K1 actually cut titanium and steel?
Yes. Titanium and steel are both on InfiMaker's material list, and the campaign's own demo video shows the tool changer running hammer-head cuts in stainless steel and brass. The InfiFlow coolant upgrade protects tool life once that cutting becomes routine.
How does the InfiMaker K1 compare with the IFMAKER M5 and TOPFAB TF500?
As fellow 5-axis desktop CNC machines, the IFMAKER M5 and TOPFAB TF500 run simultaneous five-axis motion, the M5 spinning to 60,000 RPM against the K1's 20,000. TOPFAB's list stops short of steel, and M5 markets steel and titanium cutting though its test cuts document only titanium. The K1 lists both outright, with steel demoed cutting stainless on camera.
Do I need CAD experience to use the InfiMaker K1?
No. InfiStudio can generate a machinable model from a text description or a photo, then simulate the toolpath automatically, though AI generation needs an internet connection. Experienced users can still import STEP or STL files from their own CAD software, and core machining runs offline.
What's the warranty on the InfiMaker K1?
K1 carries a 1-year limited warranty against defects in materials and workmanship under normal use, beginning on delivery. It doesn't cover damage from misuse, accidents, unauthorized modifications, or normal wear, and terms can vary by local consumer protection law.
Where does the InfiMaker K1 ship, and what does it cost?
InfiMaker ships worldwide except India, with cost by region: $140 for Taiwan, Hong Kong, and mainland China, $250 for Japan and South Korea, and $300 to $400 elsewhere, collected through a post-campaign survey.
