Why Changing Colors Costs So Much<\/h2>\n
Most multi-color printers<\/a> connect multiple filaments to a single nozzle. To change colors, the printer retracts the active filament and loads the next one. It then extrudes a small amount of plastic to clear the previous color. This excess material is called purge. It usually ends up in the trash. The waste multiplies on parts that change color several times per layer. According to InfiMech, each change takes tens of seconds. This can increase print times for these models.<\/p> InfiMech\u2019s comparison of the purge waste produced by the MX series and by other multi-color printers when printing the same part<\/p><\/div>\n The MX series skips this step because each material uses a dedicated printhead and nozzle. Unused printheads park at the back of the machine. The printer grabs the one it needs, much like switching markers. Each nozzle prints only one material, so no leftover colors need clearing. The company states that a single purge per printhead at the start of the job is enough.<\/p>\n Wait times are usually the weak point in these systems. To prevent dripping, the parked printhead stays at a lower temperature. It must heat up again before printing resumes. InfiMech uses induction heating to warm the metal of the nozzle via a magnetic field. This method reaches the target temperature faster than a conventional heater. It reduces the wait time between changes.<\/p>\n The MX Pro\u2019s eight printheads, parked at the back of the machine. Each one has its own filament and its own nozzle<\/p><\/div>\n Both printers also feature error detection systems. Closed-loop motors correct the printhead position if a bump or jam shifts it. This prevents layer misalignment. Sensors trigger an alert and stop the print if plastic builds up on the nozzle or the filament tangles.<\/p>\n The MX features an open frame, six printheads and a build volume of 220 \u00d7 220 \u00d7 220 mm. It targets makers and design studios working primarily with PLA and PETG, the most common filaments. Because the frame is open, the manufacturer does not recommend it for technical plastics like ABS, ASA or PC. These materials tend to warp if they cool too quickly.<\/p>\n The MX Pro solves this problem with an enclosed housing and a heated chamber. This maintains the interior temperature between 60 and 65\u00b0C. The printer can handle ABS, ASA, PC, nylon and carbon fiber composites. These materials suit parts that must withstand stress or heat. It features eight printheads and a build volume of 300 \u00d7 300 \u00d7 300 mm. It targets engineers, prototyping workshops and R&D teams.<\/p>\n The MX Pro also stores filament in sealed enclosures to protect moisture-sensitive materials. An auxiliary feeder with a buffer system helps guide very soft filaments, which tend to bend and jam. According to InfiMech, this allows it to print TPU as soft as 75A on the Shore hardness scale.<\/p>\n Build volume comparison between the MX (220 \u00d7 220 \u00d7 220 mm) and the MX Pro (300 \u00d7 300 \u00d7 300 mm)<\/p><\/div>\n InfiMech outlines three main uses. The first is multi-color parts, such as architectural models or figurines. The reduction of purge waste is most noticeable here. The second is prototypes that combine rigid and flexible materials. A housing with soft grip areas or integrated gaskets can print in a single job. This eliminates the need to manufacture and assemble parts separately.<\/p>\n The third use involves supports. They are easier to remove if printed with a material that does not stick strongly to the part, such as PETG<\/a> on PLA<\/a>.<\/p>\n The Kickstarter campaign launched on November 10th and is currently live. With the Super Early Bird offer, the MX starts at $299 and the MX Pro at $549. Backers with a VIP reservation will also receive a $50 refund once the campaign ends. The company states it will ship the machines in batches a few months after the campaign ends.<\/p>\n Both printers will be on display at Formnext 2026 from 17 to 20 November in Frankfurt (Hall 12.0, Stand E22<\/strong>).<\/p>\n What do you think of InfiMech’s MX series?
