If you want to 3D print engineering-grade objects, materials like PEEK, ULTEM or PEI come up sooner or later. They offer excellent mechanical strength, chemical resistance and also withstand high temperatures. Unfortunately, there aren’t many desktop machines that can reach the temperatures needed for printing these materials.
The Intamsys Funmat HT Enhanced checks off all these essential boxes – and does that for an exceptionally low price. The solidly built desktop machine was created by Intamsys – an abbreviation of INTelligent Additive Manufacturing SYStems – a 3D printer manufacturer based in Shanghai. And unlike most of its more established competitors, which have pricier machines starting from $20.000, the HT checks in at a relatively reasonable $6,000.
This machine offers a lot of handy design features as well as essential tools that ensure printing with engineering-grade materials like PEEK, PEI, PPSU, and ULTEM. Here’s what we out.
For the benchmarking element of our review, we use the following guidelines:
Unbox the printer: We unbox the printer and assemble it according to the manufacturer’s instructions. Deficiencies and errors are noted and build around according to the consensus online for the printer.
Filament: We use white eSun PLA+ filament. Temperature settings are 215 °C for the nozzle and 60 °C for the bed.
Printing: We print two test models — Benchy and the Kickstarter x Autodesk FDM 3D Printer Assessment — using the manufacturer-provided/recommended slicer and settings. If the printer ships without a dedicated slicer and profile, we generate a generic Cura profile using the essential information of the printer.
After the first print, we inspect the object for easily fixable problems (i.e., a loose belt or a poorly leveled print bed) and then print again. If the printer can’t provide a decent result after three attempts, we stop. Printers that fail to produce a test object receive zero points for the respective test object.
The Benchy 3D printer torture test is one of the world’s most popular prints. It helps to measure the dimensional accuracy capabilities of your printer and helps highlight other visible print nastiness.
We measure our best Benchy print using digital calipers, scoring 15 criteria against their target value. A total of 15 points are available.
To accommodate the difficulty and inaccuracies when measuring small features, we have implemented a sliding scale of tolerance in our scoring. The smaller the feature, the greater our allowance for deviation:
Finally, we do a visual inspection and note any flaws and problems we encounter.
The Kickstarter x Autodesk print exposes an FDM printer’s precision via six distinct tests in one object.
By pushing a printer’s hardware and software the system to the point of failure, the print reliably visible imperfections that can be used to assess the performance of the slicer, the extruder, and the motion system together.
Here’s what’s getting measured.
The tolerances and measurements are very detailed. You can find the exact measuring procedure on Github. The highest possible score is 30, indicating a very well-calibrated system.
It’s worth noting that these benchmarking tests are not a definitive measure of a printer’s worth. More an indication of a printer’s state out of the box with no-tinkering, it’s only after a full evaluation and in-depth review that we fully judge a 3D printer.
