INTAMSYS Funmat Pro 310 NEO Review: A 100C Chamber IDEX Machine That Holds Up

Most desktop printers that claim dual extrusion are lying by implication. One toolhead parks, swaps, and comes back, which is fine for a two color vase and miserable for anything structural. The Funmat Pro 310 NEO is a different animal. It has two nozzles that move independently on the same gantry, and a chamber that actively holds 100C. That combination puts it in a genuinely useful spot for small manufacturers who need engineering polymers without the four figure lead time of a job shop.

Why IDEX Matters

Independent dual extrusion buys you four separate modes. Duplicate mode runs both nozzles at once, so you get two identical parts per build. Mirror mode does the same for a left and right pair. Dual material mode puts two filaments in one build, which is how you get a soluble support interface without tearing the part apart. Support mode dedicates the second nozzle purely to breakaway or soluble scaffold.

That last one is where this machine earns its keep. INTAMSYS ships a water soluble support called SP3030, and in third party testing it dissolved faster in hot water and printed far more cleanly than PVA, across PA6, PA6 CF, TPU 95 A and ABS. Zero gap interfaces on complex geometry is exactly what you want when the part is going to a customer rather than a display shelf.

The Numbers

The 3D Printing Industry engineering team ran 42 parts of PLA at 0.20mm layers to isolate machine precision from material behavior. Pass mark is a mean deviation under 0.1mm with a standard deviation under 0.05mm. The 310 NEO cleared it on all four geometries.

• Squares: mean deviation 0.0167mm, standard deviation 0.0169mm
• Internal hole on the square test: 11.9758mm against a 12mm target
• Z height: 0.0167mm mean, 0.0233mm standard deviation
• Length, the tightest dimension: 0.0092mm

A 150 piece process capability run produced a Cp of 4.49 and a Cpk of 2.01. Overall benchmark score was 85.15 out of 100, with the points lost coming from retraction and, to a lesser extent, steep overhangs.

Where It Falls Short

Three things. Default print speeds are slow, and you will be overriding them. Edge adhesion is inconsistent enough that rafts or a manual glue layer are still sensible insurance on the first layer. And IntamSuite, the CAD style slicer, is capable but has shown instability. The overhang detection view and section clipping tools are genuinely good, but a crash mid job in the slicer preview is a bad afternoon.

There is a build volume tradeoff too. You get 305 x 260 x 260mm in single extruder mode, dropping to 260 x 260 x 260mm in dual material, since both extruders share the envelope.

Dry Box and Details

The IntamBox is a thermostatically controlled dry box using molecular sieves with an integrated hygrometer. For PA12 CF or PPA CF work this is not a gimmick. It keeps filament dry going into the print, though it will not rescue filament that already absorbed moisture, which still needs a proper drying cycle first.

Other bits worth knowing: a 7 inch full colour touchscreen, automated mesh bed levelling with Z compensation, toolless quick release print heads, a door lock interlock, over temperature and overload protection, and a combined HEPA plus activated carbon filtration setup. Nozzles ship at 0.4mm with 0.25, 0.6 and 0.8 available. Max hotend temperature is 350C with direct drive dual gear extrusion on standard 1.75mm filament. The frame is stainless steel with dual Z ball screws and LDO NEMA 17 steppers.

Who Should Buy It

At 8,495 to 9,495 dollars, this is a real machine at a price that stops SMEs outsourcing every functional prototype. If you need PC, PPS, PA or carbon filled composites, need soluble supports, or need two materials in one build, the 310 NEO does things in its bracket that nothing else does as cleanly.

If you are printing decorative PLA, buy a Bambu. The heated chamber, the IDEX and the dry box are wasted money on a lamp shade. Buy this one when the parts have to work.
