The PrototypeBD Blog
What a first 3D printer should do in 2026, what PrototypeBD stocks and what it costs, which filaments suit an open-frame printer, and when ordering prints is the better choice.
Optical vs electrical watts, work area, materials a diode laser can and can't handle, safety, air assist, accessories and software, with the AlgoLaser machines we stock.
Why to prototype before tooling, what form, fit and function prototypes test, and how tight printed fits can be, with eight projects from our Dhaka workshop.
Eight electronics enclosures PrototypeBD designed or printed, from an IoT gas meter to an MPPT charge controller, and the wall, boss, vent and material rules they show.
FDM for parts that must work, SLA resin for parts that must look perfect up close. A sourced comparison of detail, strength, size, cost, post-processing and safety, with a checklist.
What PrototypeBD's robotic arm, rover, self-balancing robot, drone and gear-model prints show about orientation, gears, shafts and filament choice for student robotics.
The A1 China and Global versions are the same printer, but the China unit is region-locked: no Handy app or cloud outside China, and no Bambu cross-regional warranty. Here is what that means in Bangladesh.
Which 3D printer filament to use for which part, how the common materials compare on heat and moisture, and how to store filament in Bangladesh's humid climate.
Why FDM overhangs sag, what the 45° rule really measures, how bridges work, and the design and slicer changes that let you print without supports.
