Anycubic has delighted 3D printing lovers with a brand new improve, the quick Anycubic Kobra 2. You may order this FDM 3D printer on the official web site for simply $209, or get it with improbable Gambody & Anycubic Kobra 2 Bundles on gambody.com and luxuriate in further perks similar to lovely fashions for 3D printing.
Following Gambody’s time-honored custom, we will probably be pleased to overview the Kobra 2 printer, unbox it, discover each element, specs, and dimensions, unscrew each bolt, and share every part with you.
Anycubic Kobra 2
The brand new Anycubic FDM printer is available in a small field weighing beneath 20 lbs (about 9 kg). Whereas unboxing, we like how nicely the Anycubic Kobra 3D printer is packed. Every half is surrounded by a thick layer of polypropylene, which maintains the integrity of all contents even when the field is by accident dropped.
The very first thing we see on high is the PEI construct plate. It has turn out to be a superb commonplace for 3D printing, and we’re glad that our acquaintance with the brand new Anycubic Kobra begins with this component.
Subsequent, we are able to observe two giant 3D printer components that join simply utilizing the 4 bolts.
Additionally, we are able to see a 4.3-inch full-colored LCD Touchscreen (one other glorious commonplace by Anycubic), which we loved working with whereas reviewing the Anycubic Vyper 3D printer. There may be additionally a model new print head, which we’ll focus on in additional element beneath.
Kobra 2 Print Head
The very first thing catching your eye is the branded Anycubic printer 4-watt fan with two air channels extending to chill the nozzle on each side and permit for extra environment friendly filament cooling. The turbine-type cooler has a pass-through channel for cooling. You’ll find comparable coolers on some highly effective laptops.
There are holes for air flow on the edges and an induction sensor to calibrate the space between the nozzle and the mattress on the reverse aspect.
Right here, you can too see the highly effective 60-watt Volcano-type heater (quite a bit!) and a small fan behind the radiator to chill it. On high of all of it, you possibly can see the NEMA 17 extruder motor, smaller than that used within the earlier Anycubic 3D printer model. NEMA 17 is positioned instantly above the hotend, that means it’s going to make the printer head work quicker and simpler.
Anycubic engineers labored nicely on the Kobra 2 printer head design. Basically, we’re happy with its monolithic meeting and last look.
Kobra 3D Printer Body
The primary body has an SD card slot and a USB port as a substitute of a micro USB (what a big enchancment!) for laptop connection on the entrance. On the decrease aspect is a 400-watt energy provide, which is kind of highly effective for this Anycubic Kobra 2 3D printer, and a controller board with a protecting cowl for the processor.
Once you unscrew this cowl, you will note an enormous cooler that cools the mainboard. It is a superb answer as a result of it operates with much less noise whereas offering a superb cooling impact.
Anycubic Kobra 2 has a TriGorilla Professional B v1.0.2 mainboard and HDSC hc32f460 32-bit microcontroller with a Cortex-M4 CPU operating at 200 MHz. The brand new Anycubic printer should not have any efficiency points due to its highly effective core. And also you’ll like the truth that the drivers are quiet.
Apart from, this Anycubic Kobra 3D printer boasts a brand new leveling system, which we’ll look nearer at after assembling and testing the machine.
Overview & Meeting
Kobra 2 comes as a typical package. It has a small spool of filament to check, a spare nozzle, and an 8 GB flash card with an adapter, with each half individually bagged and numbered. Sadly, there are not any reducing pliers for filament within the package.
The Anycubic Kobra 2 meeting requires a minimal period of time. It took us half-hour from unboxing to operating the primary check print. All you must do is join the Z-axis with the Anycubic Kobra 2 mattress, set up the print head, and join the Touchscreen. Then, you possibly can get pleasure from Anycubic Kobra specs by making your first 3D prints.
Anycubic Kobra 2 comes with three directions. One shortly explains methods to assemble the 3D printer. The opposite two present a extra detailed description of the method and can be found within the print and digital variations.
We advise you to comply with the extremely correct directions that describe the Kobra 2 meeting step-by-step. We had no points, and you’ll succeed, too! Additionally, as famous in our earlier Anycubic 3D printer opinions, you all the time really feel like having a high-quality branded product if you assemble their machines. Every half is given the proper coat of paint. All Kobra 3D printer components match collectively extremely precisely. The bolts are of excellent high quality, and so forth.
Many Anycubic 3D printers are nice. This firm has developed new guides that the parts will experience on we haven’t seen in different manufacturers. Their product is between commonplace guides with rubber rollers and rail guides. Kobra 2 has iron rollers that experience on a spherical rail. You may regulate the stress of the wheels by tightening the eccentric nuts, simply as you do on commonplace guides.
After meeting, the Anycubic Kobra 2 3D printer appears improbable. We wish to be aware a particular protecting connector used for the print head wires, which ought to stop wires from bending throughout the machine operation. As well as, the wheels roll nicely alongside their guides, and we didn’t should tighten the nuts.
Anycubic Kobra 2 Dimensions
We talked about the field weight of beneath 20 lbs (about 9 kg). Now it’s time to look nearer at Anycubic Kobra 2 dimensions. The product is nineteen.13″ x 19.13″ x 16.93″.
Anycubic Kobra 2 Mattress Measurement
The 3D printer dimensions supply a superb construct quantity for unimaginable residence initiatives. Anycubic Kobra 2 mattress measurement is 230 x 230 mm (9.06″ x 9.06″). Nevertheless, the print space is 220 x 220 x 250 mm (8.7″ x 8.7″ x 9.8″), which is sufficient to create a variety of fashions, from easy smaller components to complicated objects you could find on gambody.com 3D printed market.
The mattress is roofed with a magnetic PEI plate.
Evaluating Kobra 2 to Vyper
Kobra 2 appears just like Anycubic Vyper: the mattress has a inflexible fixation and requires no calibration utilizing springs, and the Touchscreen comes with an interface equivalent to Vyper’s.
The primary distinction between Vyper and the brand new Kobra 3D printer is just one motor however two shafts you see for those who look behind the machine. A transmission belt drives the second shaft into movement, having the identical working ideas as within the Voxelab Aquila D-1 3D printer we reviewed beforehand.
The Touchscreen has a typical interface as in another Anycubic 3D printers. It really works quick! The flash drive coming with Kobra 2 gives a number of fashions for 3D printing and calibration assessments. Thus, you possibly can get pleasure from printing if you assemble Anycubic Kobra 2. You should full FDM printer mattress calibration beforehand, as described beneath.
Mattress Calibration
Anycubic Kobra 2 has an up to date LeviQ 2.0 calibration system. It means now you can neglect about calibration utilizing a chunk of paper. The printer’s construct plate is secure and dependable. Utilizing an inductive proximity sensor, the machine first maps the proper distance between the mattress floor and the nozzle tip at 25 factors. After this, a novel contact sensor measures how far the nozzle is above the construct plate. The extruder nozzle preheats and cleans the filament residues on a particular silicone pad.
Your machine is able to print after calibrating the Anycubic Kobra 2 mattress. Relying on the 3D printing mannequin, you would possibly must calibrate the nozzle top by 0.05 mm (increased or decrease), which you’ll regulate within the settings.
To conclude, Kobra 2 mattress calibration is approach higher than on different price range FDM 3D printers. Gambody favored it rather a lot!
Testing Anycubic Kobra 2 3D Printer
You possibly can discover a slightly noisy print head fan. We perceive that it’s important to chill filament as shortly as attainable if you 3D print at excessive speeds, and that’s why Anycubic put in a robust dual-sided 4.8 W turbine on Kobra 2. However you possibly can’t escape physics. The excellent cooling impact comes at the price of noise. To decrease it, you should scale back print and fan speeds. Nonetheless, to defend the noisy “monster,” we should always affirm that the fan supplies a improbable two-way cooling impact.
Our first calibration check was printing skinny squares on the corners of the construct plate to substantiate glorious mattress calibration.
The following check was to 3D print the long-lasting #3DBenchy boat. The flash drive that comes with the Anycubic printer gives a number of settings for this mannequin that rely on the layer thickness.
Gambody staff printed a number of ships in several settings. Kobra 2 copes nicely with cooling the filament whereas constructing bridges and overhangs. However the excessive pace might be approach too extreme. We imagine the kinematics can’t deal with accelerations and jerks at such speeds, although the print head can.
For our overview, the subsequent Anycubic Kobra 2 check is to 3D print one of many fashions saved on the flash drive. You may see the top quality of the cooling system if you work on skinny components, create corners with overhangs, and see the hole high quality between the components.
After testing Kobra 2, we began to 3D print fashions from Gambody 3D printed market.
Anycubic Kobra Upgrades
When presenting Kobra 2, Anycubic changed the Ultimaker Cura with its AnycubicSlicer and PrusaSlicer profile. We’re not upset as a result of PrusaSlicer boasts some glorious specs forward of Cura. We like its algorithm for laying layers and dealing with helps.
You might be suggested to not set up the PrusaSlicer model that arrives along with your Kobra 2 as a result of it’s outdated. It’s higher to work with Anycubic Kobra upgrades, so obtain the most recent slicer model and switch a Profile for the Anycubic Kobra 2 from Cura saved on the flash drive.
Additionally, Anycubic lets you set up its preset PrusaSlicer profile. There is just one profile setting for PLA with a layer top of 0.2 mm, which is best than nothing. Nevertheless, hobbyists whose common slicer choice is Cura can safely add the Kobra 2 profile with 220 x 220 x 250 mm construct quantity and the Direct Extruder. You should use the settings shared by Gambody together with the speeds described beneath. We haven’t studied the AnycubicSlicer but, however it appears to be based mostly primarily on PrusaSlicer with some visible interface changes.
3D Printing on Anycubic Kobra 2
The primary correct mannequin we wish to check print on Kobra 2 is Dwarf Bust. It’s a complicated venture with many positive particulars and overhanging components.
At first, we tried printing with the usual settings supplied by Anycubic, however they aren’t appropriate for constructing correct, extremely detailed fashions. Kobra 2 was too loud.
To enhance this example, Gambody created distinctive settings that take into account all these details and assist the 3D printer construct excellent initiatives with positive particulars and sophisticated overhanging components. We examined these settings, and the meeting E.T. the Further-Terrestrial 3D Printing Figurine turned out improbable! Even its skinny fingers printed with out points.
The whole lot is ideal with the retracts, too, however the settings are usually not commonplace.
The third mannequin 3D printed on Anycubic Kobra 2 is Tyrion 3D Printing Figurine from Sport of Thrones. We printed the one-piece SLS model on the brand new Anycubic FDM printer, and the result’s unimaginable!
Print Settings
Anycubic states that Kobra 2 can function at excessive speeds with a most print pace of 300mm/s and accelerated pace of 3000mm/s². Its print head is able to this. Nevertheless, it might assist for those who approached the excessive speeds correctly.
You should use the usual settings provided by Anycubic when printing one thing important with easy sides and with out sharp corners (for instance, a field with rounded edges). However if you want to 3D print high-quality fashions with particulars, decreasing the pace and acceleration by 30 to 40 % is best. Kobra 2 will nonetheless print quick, however the printing high quality will enhance. Gambody, for example, lowered the speeds and accelerations beneath the figures shared by Anycubic however saved them increased than those supplied by Prusa.
Recommendation: We used tree helps as a result of they save the filament and could be eliminated ideally from the fashions. Anycubic PLA Gray is the perfect filament to make use of by way of worth/high quality.
