  • A truly excellent 3-D printer
My first 3-D printer was a StrataSys TITAN, at a cost of $238,000 (USD) in 2004. I am old-skool, so I call it an "FDM" (fusion-deposition modeler). This was affordable on my DARPA research budget, It was the size of a large commercial double-door refrigerator. It had a huge build volume, could print in polycarbonate, and cost more than my home mortgage just to keep it fed. I used it extensively in the development of several biomedical devices, many of which have since become globally available products, with several additional products still in the pipeline. I mention this because I want to establish that (1) I am a serious FDM user, and (2) I have quite a different perspective than people who have recently developed their interest/expertise in this area. I have since owned a few additional commercial-quality FDMs, I have purchased them for use in universities and private companies. I needed one at home for development of plastic components for my consulting and "hobby" consumer products, which usually end up getting transitioned into production tooling such as injection molds. I have enjoyed watching the quality and affordability of FDM systems converge on the products we have today. So, with my intended use and experience, I chose the "R QIDI iFast 3D Printer", which is more expensive than the "toy" 3-D printers priced at a few hundred dollars, but I needed the extra quality. Right out-of-the-box, I had it up and running. I need 945 individual components built (PLA), and they had to be of saleable and functional quality, not just trinkets. I ran the machine for 7 weeks continuously, day and night, with an alarm clock schedule for build changes at all times of day and night. The FDM ran almost without a glitch, but I did have a learning curve. I will describe some of my experiences to help both the potential buyer and the manufacturer, to improve their excellent product. - You need to use good filament. I use SUNLU PLA+ - You need to use their filament drier canisters to keep the filament dry while printing - The force required to draw the filament from the canister is too high. I had to do a few modifications to get around this because it was causing filament breakage. - You must also use the filament guide tubes since you really can't just run the filament from an open spool into the melt head because the draw force is too high and the filament rubs on the top cross beam of the X-Y gantry. Most of their instructional videos omit this and just show filament being fed from the spool directly into the melt head. But this leads to poor build quality and broken filaments. To fix this problem and get perfect results every time, here is what I did: I very lightly waxed the inside of the filament dryer canisters where the spool rubs against the inner cannister surfaces. This greatly reduces the rolling friction of the spool, which causes more problems when filament gets low due to the reduced torque applied by the filament to the spool because the line of action of the filament force on the spool is approaching the inner diameter of the spool (lower radius = less available torque to spin the spool = broken filaments). I am confident that the smart engineers at R QIDI TECHNOLOGY will fix this problem. I also bypassed the broken filament sensor, which is a small hole/port that the filament is supposed to pass through right after it leaves the spool. I had to do this because their broken filament sensor was adding a lot of drag force to the filament (about 1/2 N!!!). This was preventing the filament from being drawn properly into the melt head. This is a very serious problem. It was happening on both sides (both spools), so I am inclined to think it is a design error, not just a manufacturing error for my system. The broken filament detector should be an optical, NON-CONTACT, zero-drag apparatus, but it is not. R QIDI TECH definitely needs to fix this quite serious design problem, and I am confident that they will do so. Also, I will offer to give detailed design guidance to the company if they want my help to fix this design deficiency, because once fixed, their product will be very nearly flawless. Finally, I would say they need to have transparent filament dryer boxes to allow the user to see the spool from all angles while in the drum/box. Aside from these problems, all related to the filament feed system, their product is excellent. It is intuitive to use, with good quality components. The build results are excellent if you are willing to work around the few remaining design corrections they need to make. ... show more

  • Great Option for Dual Extrusion/Multi-Material Printing
I use this printer to build custom implements that need to be clean and accurate, print reasonably quickly, and often exceed the size of typical beds. I have found the iFast to be a great option for my application. I most often am printing with PLA and using PVA support. I have tried a couple multi-material printing solutions, and so far, they really don't stack up to the performance this printer offers. The mechanism the printer uses to swap between extruders is simple and clever, so the failure modes that other multi-material printers suffer are not an issue. The design of the extruders themselves is also simple and effective making them easy to swap and maintain. There is also minimal waste associated with the printer's operation. Some machines that have greater printing speed, for instance, but still use a single extruder for multiple filaments, lose a lot of product switching between materials (not to mention substantially driving up printing time). This printer boasts a very large heating bed with good temperature uniformity. Prints that test those boundaries, can have adhesion issues due to the temperature gradient of the contiguous structure itself and the gradient of the bed at its boundaries. I can say this is the only printer I've used where printing to the full size of the bed works pretty consistently without having to actively take pains to assure that it does. One thing I'd love to see on a printer like this that is currently available from competitors is detection of print failures. I'd assume most who find utility with a machine of this size with dual extrusion are trying to produce larger/more items within any given print session to increase scale efficiently, so detecting failures that push notifications would be great. I am experienced enough with 3D printing to know that no printer is without its occasional failures and need for troubleshooting those failures. I have not had any mechanical issues, and everything is intuitive and accessible enough that I'm not particularly worried about them if/when they may occur. Within my year and a half of pretty heavy use of this unit (often running prints that may take 20+ hours), I did run into an issue that ultimately caused a failure of the node on the mobo controlling one of the extruders. Customer support was very quick and responsive, sent out a replacement alongside video instructions, and I got the machine up and running in short order. Painless process, really, which is frankly becoming a bit of a novelty. All told, especially if you have utility for dual extrusion, this is a great choice. ... show more
