Build Envelope Frame
An adjustable metal frame that defines the printable volume in gantry-style additive manufacturing systems. It provides structural support and alignment for the machine's moving components, making it an essential part of the 3D printer.
Build Plate for SLA Resin 3D Printer
A flat, optically clear build platform used in stereolithography (SLA) 3D printers. The plate holds the printed object during the resin curing process and is a key component of the machine's build area.
Gas Flow Nozzle for Inert Atmosphere AM
A nozzle that directs inert gas, such as argon or nitrogen, into the build chamber of powder bed fusion printers. It prevents oxidation of metal powders during the additive manufacturing process, ensuring part quality.
Heated Chamber Enclosure Panel
An insulated panel used to maintain elevated temperatures (up to 200°C) in the build chamber of polymer or metal additive manufacturing printers. It prevents warping of printed parts by ensuring a stable thermal environment.
Laser Module for SLS Powder Bed Fusion Printer
A high-precision laser diode module used in selective laser sintering (SLS) additive manufacturing systems. It fuses powdered materials layer by layer to create solid objects, making it a critical component of the machine.
Layer Adhesion Roller
A roller that ensures proper layer bonding in continuous filament winding additive manufacturing machines. It applies pressure to the deposited material to improve adhesion between layers.
Powder Containment Hopper Lid
A sealed lid with a sieve for powder supply hoppers in binder jetting or SLS additive manufacturing printers. It prevents contamination and ensures consistent powder flow during the printing process.
Reciprocator Arm for Metal DMLS Printer
A mechanical arm assembly that spreads metal powder evenly across the build platform in direct metal laser sintering (DMLS) machines. It ensures uniform powder distribution for consistent part quality.
Resin Vat Assembly for DLP Printer
A transparent vat holding photopolymer resin for digital light processing (DLP) additive manufacturing. It includes a release film and leveling features to ensure accurate layer curing.
Software Calibration Fixture
A mechanical fixture used for printer bed leveling and nozzle calibration in Cartesian additive manufacturing systems. It ensures accurate print starts and consistent layer alignment.
Thermal Break Cartridge Heater
A cartridge heater that isolates heat in extruder hotends for FDM printers. It provides precise temperature control for melting plastic filament during the deposition process.
UV LED Curing Lamp Array
An array of UV LEDs used in post-processing curing stations for resin additive manufacturing workflows. It provides uniform UV light to fully cure printed parts after printing.
Vibration Isolation Mount for Industrial AM Machine
Rubber-metal mounts that reduce vibrations in large-format metal additive manufacturing systems during high-power laser operation. They ensure machine stability and precision.
