Best practices, tutorials, and innovations in custom acrylic fabrication, including forming, cutting, polishing, and more.
Bubbles, starved joints, crazing, blush, and creep — five distinct failure modes that get misdiagnosed as “bad glue.” Each one’s mechanism, its prevention, and the diagnostic order that tells you which problem you actually have.
PETG dominates high-volume formed packaging for good reasons; acrylic owns the formed part whose surfaces and edges are the product. The honest split between the two clears, and the one edge-finishing fact that decides more of these calls than any datasheet line.
The part looked perfect leaving the laser — and crazed into a web of micro-cracks the moment cement touched it. Annealing is the oven cycle that prevents that failure, and it is invisible in every part it saved. What it is, when it’s required, and how to spec it.
Thermoforming is the process that gets acrylic out of flatland — heat the sheet, shape it over a tool, cool it, trim it. The process walk, what forming does to the material, why the mold is the real product, and why trim is half the job.
The most common field disappointment in display work is a shelf that sagged — slowly, months after delivery, exactly as the physics said it would. How span, load, and time actually pick a thickness, and why one step up in thickness beats almost every other fix.
Three ways to put a brand on acrylic — printed direct and UV-cured, pushed through a stencil, or applied as film — and three different answers on color, durability, run length, and change cycles. How the job picks the method.
Solvent cement welds acrylic into acrylic; two-part cement cures into a structural layer; UV-cure trades chemistry for timing; and sometimes the honest answer is screws. The four joining routes, judged the way joints should be judged — by the standard, not the folklore.
The word polished names neither a method nor an acceptance criterion. How the Acrylic Fabrication Standards Framework splits finish into what was done to the edge, how good the result must be, and how bonded joints are judged — one coherent spec language.
CNC routing and laser cutting are not competitors — they are answers to different questions. How edge character, geometry, tolerance, and quantity route acrylic work to the right process, feature by feature.
Glass wins on surface hardness and cleaner tolerance — concede that up front. Then weigh what acrylic changes at the project level: weight through every mount and wall anchor, non-shard failure around people and artifacts, and case forms glass cannot be built into.
