Is the CTC 3D Printer Still Worth Buying Today?
If you have invested any time moving through eBay or local classifieds with regard to a bargain, a person have almost definitely stumbled across the ctc 3d printer . It's among those machines that will appears to exist in a strange limbo between "vintage" hobbyist tech plus a surprisingly capable workhorse for people on a budget. Usually sporting a wooden body and a dual-extruder setup, it's a clone of the old MakerBot Replicator series, and regarding many of all of us, it had been the entrance drug into the particular world of preservative manufacturing.
Yet let's be true for a second: the 3D publishing world has shifted fast. We're in an era of auto-leveling, silent stepper drivers, and touchscreens. So, does a clunky, wooden-framed machine like the CTC still possess a location on your own workbench, or is definitely it just the relic of the bygone era? Let's dive into what it's actually such as to live along with one of these simple things.
The First Impression: The Box of Possible (and Wood)
When you pull the CTC 3D printer from the box, the particular first thing you observe is the smell. Because so many of these versions use laser-cut plywood for your frame, these people have this distinctive burnt-wood aroma. It's a bit wonderful in a DIY sort of way, though it definitely feels less "high-tech" than the particular sleek aluminum extrusions you see on an Ender or a Prusa.
The particular setup isn't exactly what I'd contact "plug and have fun with. " While it generally comes mostly put together, there's a lot of looking at and double-checking involved. You'll find yourself tightening up bolts that vibrated loose during delivery and ensuring the wiring hasn't arrive unplugged. It's the kind of machine that demands a person understand how this works before you even hit the "print" button. If you're the type of person who else loves taking things apart just to see the courage, you'll probably love it. If you want a microwave-style encounter where you simply push a switch and get a gadget, you will probably find yourself frustrated within the first hr.
The Double Extruder Paradox
One of the greatest selling points from the ctc 3d printer has always been typically the dual extruders. In the day, getting a dual-nozzle machine regarding under $500 was unheard of. The concept is great: you can print in 2 colors, or make use of one nozzle with regard to the actual part and the various other for dissolvable assistance material like PVA.
In practice? It's a little bit of a headache to get perfectly arranged. When the two nozzles aren't exactly level with one another, the "idle" nozzle will usually catch around the print and knock it right off your bed. I've spent more time than I'd want to admit shimmying the nozzles with small pieces of aluminum foil to get them perfectly in-line. However, as soon as you do have it dialed in, it's extremely satisfying. There's some thing special about viewing a machine from ten years ago crank out a two-color benchy that will looks just simply because good as some thing from a modern device.
Why A person Absolutely Need in order to Flash the Firmware
If a person buy a CTC today, the stock firmware is probably going to feel like utilizing a flip phone in the age associated with iPhones. Most customers immediately jump to installing Sailfish firmware . This is virtually non-negotiable if you want to have a good time.
Sailfish unlocks a great deal of features the stock software lacks, like better acceleration control (which halts the wooden body from shaking alone to pieces) and much more precise temperature supervising. It also can make the menu program a lot easier to navigate. The community support intended for the CTC 3D printer and Sailfish is massive. Although the manufacturer's own assistance is basically nonexistent, you will discover a community forum post or a YouTube video for literally every individual problem you may encounter. That's the beauty of these older "open" devices; someone else has currently suffered with the issue you're having plus posted the repair online.
The Tinkerer's Transitional phase
I often inform people that having a CTC is like buying a project car. You don't purchase it because it's the most reliable method to get to function; you buy it because you would like to learn how an engine works. To get the best results, you'll end up doing a few "essential" mods:
- The Active Cooling Lover: From the box, many CTC models lack the fan to amazing the plastic since it leaves the nozzle. This leads to "droopy" prints. Printing and installing an enthusiast duct is normally the particular first "official" purpose of a new proprietor.
- Cup Bed Upgrade: The stock heated bed is definitely often slightly warped. Clipping an inexpensive item of borosilicate glass (or even a picture frame cup inside a pinch) more than the top makes leveling a thousands of times easier.
- Frame Braces: Considering that it's wood, this can flex. Printing some plastic brackets to stiffen the particular corners helps immensely with print regularity at higher speeds.
Once you've done these things, the particular ctc 3d printer transforms. It stops being a "cheap clone" and starts being a remarkably reliable workhorse. I realize people who have got had their CTCs running for 5 or six yrs straight with nothing but basic servicing.
Let's Discuss Print Quality
Can it in fact print well? In short: Yes .
If you use a modern slicer such as Cura or Simplify3D (though getting the profiles right requires a little bit of work), the print quality will be shockingly good. Because it uses a "gantry" style movement system (where the particular bed only moves up and straight down around the Z-axis), it can often create cleaner walls as opposed to the way "bedslinger" style ink jet printers where the weighty build plate moves back and on.
It handles PLA like a champ, and because it's mostly enclosed (you can easily add acrylic edges if yours didn't include them), it actually does the decent job along with ABS too. The heat stays trapped inside the step, which prevents the particular dreaded warping plus cracking that ruins ABS prints upon open-air machines.
Who Should Really Buy One?
In a world where you can buy an Ender 3 for less than $200, why would anybody pick up the ctc 3d printer ?
Nicely, first, there's the cost. You can frequently find these utilized for next to nothing at all. If you discover one for $50 or $70 from a garage selling or on a discussion board, it's a take. It's also the particular perfect machine regarding students or teachers who want in order to teach the technicians of 3D publishing. You can discover the belts, the particular pulleys, the wires, and the motors. Nothing is hidden at the rear of a fancy plastic shroud.
It's also ideal for the particular person who wants a "dedicated" device. Maybe you have a sophisticated printer for your complex stuff, nevertheless you want the cheap secondary machine that just sits within the corner and prints mechanical components or brackets most day. The CTC is perfect for that. It's high decibel, it's ugly, plus it appears to be this belongs in the high school shop course, but it gets the job performed.
The Final Judgement
The ctc 3d printer isn't for everyone. In case you get frustrated by technical hiccups or don't like the idea of spending a Saturday afternoon recalibrating an extruder, stay far away. You'll possess a far better time with a modern, computerized machine.
However, if you have a bit of a DIY soul and you're searching for a cheap way to obtain into dual-extrusion printing, there is still a lot associated with life left within these wooden boxes. They represent a time where 3D printing was about local community, hacking, and making things work via sheer willpower. Also years after their own peak popularity, these people remain a testament to the idea that you don't need the most expensive gear to create some thing amazing—you just need the patience to dial it in.
Therefore, in case you see a single sitting in the "for sale" ad, don't just dismiss it. After some love and a firmware flash, it may just become your favorite tool within the workshop.
