Anycubic Kobra X Review After One Week: Print Results and Trade-Offs

After a week of real prints, the Anycubic Kobra X has been most convincing with everyday PLA and PETG jobs plus its four-color workflow. I got several clean results, including detailed PLA parts, a bridge-focused coaster, PETG organizers, and a multi-material PETG/PLA test. The rough edges showed up when I relied on an imported support choice, tried TPU with PVA supports, and had a long print resume after an outage.

This is the follow-up to my Kobra X setup and first-print guide. That first article covers unboxing, calibration, and the starting workflow. Here I am focused on what the machine actually produced over the first week, where the four-color process added friction, and the limits I found rather than treating a short test as a long-term verdict.

Quick verdict after one week

My one-week takeaway is that the Kobra X is a capable entry point for makers who primarily want PLA or PETG and want to explore four-color printing without treating every job as an experiment. It produced good ordinary results for me, but it rewarded checking the model and support plan rather than accepting a cloud profile at face value. I would not buy it specifically for a TPU-and-PVA support workflow based on this test alone, and I would want more evidence before relying on resume-after-power-loss for a long print.

What I printed during the first week

I deliberately moved beyond a single first-layer test. The PLA group included a two-part koi-style statue with a black frame and white insert, a pallet-style coaster to look at bridging, a small dragon used to verify settings for the site, and two larger dragon statues in different PLA materials. Those prints gave me a better read on detail, bridges, and the normal workflow than one benchmark could.

I then switched to flexible and higher-temperature materials. A TPU soccer ball printed, and the Kobra X also completed a PETG pencil holder with only minimal stringing to clean up. A PETG ball printed with PLA supports was another successful multi-material test. Those successes are useful, but they do not erase the TPU/PVA failure later in the week; both results belong in the review.

The support setting that changed the dragon result

The clearest early lesson was not to trust an imported model setting blindly. On one dragon job, the cloud/default support plan used “on build plate only.” The supports did not reach the underside of the foot and tail, leaving missing detail and a glob of filament in that lower area. The model itself was not the problem; the support strategy did not reach the areas that needed it.

When I turned off the build-plate-only restriction and reran the print, supports were able to meet the bed around the tail and support the areas that had been missed. The resulting model was much better. That is not a universal instruction to disable build-plate-only supports for every print. It is a reminder to look at the generated supports in the slicer and confirm that they actually contact the overhangs you are trying to protect.

If you are troubleshooting a model that looks fine in preview but fails underneath, start with the support contact points and then use the 3D printing troubleshooting guide for the next checks rather than changing several slicer settings at once.

Four colors work, but purge is part of the cost

The Kobra X handled the PETG-and-PLA support job, but its single-nozzle workflow purges a meaningful amount of material at each change. That makes mixed-material supports a decision rather than an automatic upgrade: depending on the size of the model and the amount of support, the extra purge can cost more material than the support material you hoped to save.

For ordinary color changes, the workflow is practical. For special support materials, I would first decide whether the improved removal or surface quality is worth the extra transitions. A model with a small amount of support may be better served by a simpler material plan. A model with difficult internal supports may justify the added waste and setup time.

Before committing a large multicolor job, use the multicolor print planner to think through the color changes and likely material use.

TPU and PVA were the unfinished part of the test

The TPU test was mixed. One soccer-ball-style print succeeded, but a different test with TPU and PVA supports failed three times. After four or five material changes, I had trouble getting TPU back out, ended up with a clogged nozzle, and opened the hotend a couple of times. In other words, the default TPU/PVA approach was not dependable for me out of the box.

There may be a better route here—for example, feeding TPU more directly instead of through the longer material path—but I did not test that alternative in the first week. I am leaving it as a limitation, not turning it into a claim that the printer cannot print TPU. If flexible material is your main reason to buy a machine, wait for a dedicated workflow test rather than treating this review as a final compatibility answer.

PETG was more straightforward

PETG was less eventful in the best sense. The pencil holder completed without a major problem and had only minimal stringing to remove. The PETG ball with PLA supports also completed. Those examples suggest the normal PETG workflow is a more natural fit for the Kobra X than the TPU/PVA experiment was during this first week.

For a repeatable starting point built from my own Kobra X prints, see the Kobra X multicolor PLA baseline in 3DPrintscape Labs. It records a specific material, nozzle, plate, slicer profile, and actual result; it is not a substitute for tuning PETG or TPU.

The power-resume result needs more testing

One large print was interrupted by a real power outage. Once power returned, the printer resumed, but the job had a visible layer shift and the 30-plus-hour print was effectively ruined. That was the most consequential problem of the week because a shift on a long job cannot be cleaned up the way light stringing or a support scar can.

I ran two smaller forced tests by unplugging the printer for roughly ten seconds, reconnecting it, and resuming. Neither of those test prints shifted. That conflict matters: I cannot say the outage result was a one-off, but I also cannot honestly call the failure repeatable. For now, I would avoid treating power-loss recovery as proven insurance for a long unattended job.

A practical first-week workflow

Based on this week, this is the workflow I would use before starting another large Kobra X job:

• Start with the stock or known-good material profile, then inspect it instead of assuming imported object settings are right.
• Preview supports from the angles that matter. Confirm they reach the lower overhangs, not merely that supports are enabled.

• Keep early multicolor jobs to PLA or PETG, and account for purge volume before adding special support materials.
• Treat TPU with support material as a tuning project. Do not schedule it as a no-risk production print until the feed path and profile are proven.
• For long prints, understand that I saw one poor real-world resume after an outage even though two short manual-resume checks passed.

Who the Kobra X makes sense for

After one week, I think the Kobra X makes the most sense for a beginner or budget-minded maker who wants a straightforward route into four-color PLA and PETG printing and is willing to learn the slicer preview. The common print results were good, and the learning moments were visible enough to correct without guessing at hidden hardware problems.

I would hold off if your priority is a fully proven flexible-material-plus-support workflow, or if you need a long-print resume feature that has already been tested over repeated real interruptions. Those are not automatic disqualifiers forever; they are simply not claims I can support from this week of use.

FAQ

Is the Anycubic Kobra X good after one week?

For my PLA and PETG work, yes: it produced multiple successful parts and the four-color workflow was usable. The more cautious answer is that I found clear limits with a TPU/PVA support attempt and an unresolved power-resume issue, so it is a good early result rather than a long-term reliability verdict.

Can the Kobra X print TPU?

One TPU soccer-ball-style test succeeded. A separate TPU job using PVA supports failed three times and created feeding and clogging trouble after several material changes. That is enough to say TPU is not yet a plug-and-play workflow in my testing, not enough to say it is impossible.

What was the most useful slicer lesson from the review?

Check whether generated supports reach the exact overhangs that need them. In my dragon test, “on build plate only” left the lower tail and foot unsupported. Allowing the supports to reach those areas improved the result.

Should I use mixed support materials on every multicolor print?

No. It worked on my PETG ball with PLA supports, but every material transition adds purge waste. Use a different support material when the removal or surface benefit outweighs that extra material and time.

What I am testing next

The first week established a usable PLA/PETG and multicolor baseline, but it also created a clear follow-up list: TPU feed-path testing, the default profiles that did not work in the support-material job, nozzle and clog maintenance, filament removal, and more long-print reliability. I will add only results I can repeat and document—not assumptions based on a single success or failure.

For the setup sequence, start with the Anycubic Kobra X setup and first-print guide, then review the verified Kobra X print baseline before copying settings into your own project.
