Cheap glue or beginner printer? The smarter buy depends on your setup

Display

There isn’t a meaningful display comparison here because Product A is an accessory and Product B is a printer with an LCD screen. On pure screen presence, Product B wins by default because it includes onboard controls and a visible interface for printer operation. Product A has no screen at all, so if you want a device you can interact with directly, the Tina2 is the only option.

Performance

Product A wins on the narrow job it is designed to do: improve adhesion and reduce warping. At £15.99, this 60ml glue is built for PLA, ABS, PETG, PC, PA and TPU, and it is specifically marketed as compatible with Bambu Lab A1/P2S/A1 Mini/P1/X1 plates. That’s a practical performance advantage if your prints are lifting at the corners or failing on textured PEI. Product B, the Tina2, is a beginner printer with auto levelling and resume printing, which is good for entry-level convenience, but its performance is limited by the machine itself and the filament list is narrower, mainly PLA/PLA Pro/TPU. If the goal is print success on a current setup, Product A is the stronger performer.

Build quality and design

Product B wins here because it is a complete physical product with a removable magnetic build plate, auto levelling, open-source support and resume printing. Those are meaningful design features that affect day-to-day use, especially for beginners who want less faff and fewer failed starts. Product A is just a consumable liquid adhesive, so its “build quality” is mostly about the bottle and formula rather than a hardware experience. UniTak3D’s glue may be well-reviewed, but it cannot compete with the tangible engineering of an actual printer. If you want a machine with hardware features and user-facing design, the Tina2 takes this category.

Battery life

Neither product has a battery, so this category does not apply. Product B is mains-powered and Product A is a passive consumable. If you were hoping for portable, cordless use, neither one is relevant.

Price and value for money

Product A wins this category decisively. At £15.99, it is £161 cheaper than Product B, and it has a strong 4.8/5 rating from 364 reviews, which suggests it is doing exactly what buyers want: improving bed adhesion reliably. For people already owning a Bambu Lab-compatible printer, that is excellent value because a small spend can prevent failed prints, wasted filament and wasted time. Product B costs £176.99 and has a lower 4.2/5 rating from 415 reviews, so while it offers a full printer for the money, it is a much bigger commitment and the feedback suggests a more mixed ownership experience. If your budget is tight, the glue is the obvious value winner.

Game library/features

This is another category where the comparison is a bit awkward because Product A has no “library” and Product B is not a game device. Translating this into practical features, Product B wins because it offers auto levelling, resume printing, an LCD screen, open-source compatibility and a removable magnetic build plate. Those features make it more versatile and beginner-friendly as a printer. Product A’s feature set is much simpler: it is an adhesion aid for heatbeds and PEI steel plates. If you want features, the Tina2 wins; if you want one very focused feature that solves adhesion problems, the glue is better at its job.

Overall user experience

Product A gives a very targeted, low-effort improvement. You apply it, print, and get a better chance of a successful first layer, especially on tricky materials like PETG, ABS or TPU where warping and release issues can be annoying. The experience is best for owners who already have a decent printer and just want fewer failed prints. Product B offers the fuller ownership experience: unpack, set up, auto-level, and start printing. It is better for beginners who want an all-in-one machine and don’t already own a printer, but it is also a bigger leap in cost and complexity. The Tina2 is more exciting as a product; the glue is more satisfying as a practical fix.

Overall, Product A is the better buy for most people searching this comparison because it is dramatically cheaper, highly rated, and solves a common real-world problem on compatible printers. Product B is the better choice only if you need a complete beginner 3D printer rather than an accessory. If you already own a Bambu Lab-compatible machine and your pain point is adhesion, Product A is the sensible, high-value purchase. If you are starting from zero and want a compact entry-level printer, Product B is the one to buy.
