Wefuit Bambu Lab Liquid Bed Adhesive Review

Wefuit packages this liquid adhesive in a cylindrical 60ml plastic bottle equipped with an internal push-valve and a porous sponge top. The mechanical premise is straightforward: pressing the applicator tip down against the build plate opens an internal valve, releasing liquid into the sponge for a clean, wipe-on pass. In theory, this eliminates the uneven ridges left behind by solid glue sticks. In practice, owners experience the applicator tax. The internal spring mechanism requires deliberate, heavy pressure to open. Push too gently and the sponge drags dry across the steel; press a fraction too firmly and the bottle discharges a puddle that requires rapid wiping to salvage. The bottle cap seals adequately to prevent early evaporation, but the valve assembly introduces unnecessary friction to what should be an effortless pre-flight routine.

Applying the fluid requires a clean plate, ideally degreased with isopropyl alcohol or warm dish soap. Spreading the liquid cold yields the best results. Owners who attempt what we term emergency mid-job patching, applying liquid mid-print to rescue a tipping purge tower, discover that the formula does not dry faster on a hot plate. Instead, it forms a sticky sludge that smears rather than cures. Post-print maintenance exposes the Dissolution Gap. If you attempt to scrape dried residue off a cooled plate with a metal spatula, the film resists like dried stucco and risks gouging the build sheet. Take the exact same plate to a sink, however, and warm tap water dissolves the adhesive film instantly without any scrubbing. The formula lives up to its water-soluble claim, provided users avoid treating it like traditional mechanical gunk.

During active printing, the adhesive balances hold and release exceptionally well. For ABS parts running inside enclosed chambers, it generates sufficient tensile grip to counteract thermal contraction along sharp corners. More importantly, it solves the catastrophic bonding problem inherent to flexible filaments. Printing TPU directly on smooth PEI usually destroys the build sheet during removal; Wefuit adhesive creates an intermediate shear barrier that releases cleanly once the steel sheet cools to room temperature. Durability between coats is another asset. Owners report running four to six cycles before needing to reapply, making the 60ml volume go considerably further than expected. The primary compromise appears on aesthetic parts. If the user overlaps passes during application, the liquid leaves distinct swipe marks on the plate that imprint directly onto the first layer of the finished print.

Because this adhesive directly mimics the factory liquid glue offered for Bambu Lab P1P, P1S, and X1-Carbon machines, it integrates cleanly with printer hardware. Unlike textured hairsprays that create airborne aerosol mist inside enclosed gantry tracks and carbon rods, this sponge-down liquid stays strictly on the build plate. It works across smooth PEI, textured sheets, and Bambu Engineering plates without causing false positives during the Micro Lidar calibration sequence. High-contrast streaks from heavy coats can occasionally cause bed inspection algorithms to flag phantom first-layer imperfections, but a thin, uniform spread clears scanning without error. The formulation behaves consistently with manufacturer slicer temperature presets, requiring no customized bed temperature profiles.

Sitting in the $15 to $20 range, Wefuit liquid adhesive occupies an awkward pricing bracket. Skeptical owners frequently point out that a multipack of standard purple craft glue costs under $5 and delivers comparable raw adhesion. That criticism is valid if raw holding power is your only metric. What buyers are really paying for here is surface uniformity and fast maintenance. A solid glue stick leaves chunky, irregular plate topography that ruins smooth bottom finishes and requires vigorous scrubbing to strip. Because this liquid formula requires only a micro-meter layer that lasts across several runs, a single 60ml bottle comfortably manages months of active hobbyist printing. It represents a modest premium for saved prep time, even if it feels overpriced compared to basic stationery alternatives.
