Außenkomponenten

ItemDescriptionImage
ShellFive protective external casings protect the printer’s internal components:
  • Right shell: metal casing for the right side of the printer; also includes the display assembly.
  • Left shell: metal casing for the left side of the printer.
  • Top shell: metal casing to protect the top of the printer, above the Z-tower.
  • Rear shell: metal casing made of orange-tinted material that covers the back face of the printer.
  • Cover: printer lid, made of metal and orange-tinted material; hinged to top and left shell.
  • Front shell: metal casing that covers the bottom of the front face of the printer (below the cover).
Leveling feetEach corner of the printer is supported by a rubber foot that is threaded into the bottom of the machine. When prompted by the touchscreen, use the leveling disc to raise or lower each foot to ensure that the printer is acceptably level.Leveling feet

Displaybaugruppe

ItemDescriptionImage

Display cableA flat, flexible cable connects the display assembly to the motherboard.Display cable

Cover

ItemDescriptionImage
CoverThe printer lid, made of metal and a strong, orange-tinted material, blocks exposure to the lasers and protects the resin from curing due to ambient light.Cover
Interlock magnetsThe interlock sensor detects these magnets to determine when the cover is closed. This safety mechanism triggers the Cover Open message on the touchscreen and disables the lasers when the cover is open.Interlock magnets

Resin cartridge

ItemDescriptionImage
Resin cartridgeTwo containers hold the resin before dispensing into the resin tank. Shake the resin cartridges periodically to keep resin well mixed.Resin cartridge
Vent capThe lid at the top of the cartridge allows for air interchange, enabling proper resin dispensing. Press the vent cap open prior to printing.Vent cap
Cartridge ID chipAn Electrically Erasable Programmable Read-Only Memory (EEPROM) chip programmed with the resin type is attached to each cartridge skirt. This chip communicates to the printer via spring fingers on the cartridge floor.Catridge ID chip
Bite valveA flexible, rubber seal that regulates resin dispensing. Resin flows out when the cartridge dispense arm squeezes the bite valve open.Bite valve

Baugruppe am Kartuschenboden

ItemDescriptionImage
Cartridge spring fingersTwo electrical contacts comprise the spring fingers located on the cartridge floor. The physical contact establishes an electrical connection with the cartridge ID chip to detect the resin cartridge.Cartridge spring fingers
Cartridge dispense armPlastic hooks press against the bite valve to dispense resin out of the resin cartridge into the resin tank.Cartridge dispense arm

Z-Achse

ItemDescriptionImage
Z-towerThis vertical tower at the back of the machine provides support for many components of the Form 3L/Form 3BL. The build platform is raised and lowered along the Z-axis, inside the Z-tower.Z-tower
Z-axis lead screwThe Z-axis lead screw controls the vertical motion of the build platform carriage.Z-axis lead screw
HeaterThe resin in the resin tank is heated by hot air blown out of the right side of the printer, next to the resin cartridges. The warm air in the print chamber heats the resin, and the air temperature is sensed by a thermal sensor at the air intake.Heater
FansTwo heating fans blow air across the heater into the resin tank.Heater fan

Plattform

ItemDescriptionImage
Build platformThe aluminum base provides a surface for prints to attach to.Build platform
Platform lockA lever that is part of the locking mechanism that secures the build platform. Contact Formlabs Support or your authorized reseller before adjusting the platform lock, as improper adjustment can damage the machine.Platform lock
Build platform carriageThe metal arm that the build platform slides onto.Build platform carriage
Build platform sensorEach Form 3L/Form 3BL build platform has an RFID sticker. The printer senses the RFID sticker to detect when the build platform is properly installed.Build platform sensor
Platform lock springThe spring mechanism inside the build platform carriage allows the platform lock to move up and down. It also mechanically locks and unlocks the build platform.Platform lock spring

Harztank

ItemDescriptionImage
Resin tankResin is dispensed out of the resin cartridges into the resin tank. During a print, two lasers pass upwards through the flexible film of the resin tank and cure resin onto the build platform to form a printed part. Only use approved materials and procedures to clean the resin tank.Resin tank
Tank handlesHandles on each side of the resin tank allow for easy insertion, removal, and carrying of the resin tank. Use the tank handles to avoid touching the resin tank’s underside, as fingerprints leave smudges that obstruct the optical path.Tank handles
Tank spoutA spout at the right of the resin tank sits underneath the cartridge dispense hole and receives resin from the resin cartridge.Tank spout
Flexible filmA durable, dual-layer film comprises the resin tank’s underside. Parts print in the resin-filled gap between the flexible film and the build platform. The print quality depends on the flexible film being clean and clear of damage and debris.Resin tank film
Resin tank RFID stickerEach resin tank has an RFID sticker attached to the back wall of the tank frame. The printer reads the RFID sticker to detect the unique tank ID and current resin type.Resin tank RFID sticker
MixerEach resin tank includes a mixer that improves print consistency by clearing the build area and circulating the resin. The mixer moves with the LPU housing via magnetic coupling and rests at the right side of the resin tank when not in use. Scrapers on the top and bottom of the mixer clear the build platform and flexible film, respectively.Mixer
Tank caseEach resin tank includes a container and a lid for storing the resin tank when not in use.Tank case
Tank toolA two-part scraper for inspecting and cleaning the resin tank interior. Separate tool for scraper function or combine for tongs. Together with the cleaning mesh, this is the only tool to clean the flexible film inside the resin tank.Tank tool

Tankträger

ItemDescriptionImage
Tank carrier railsThe resin tank side walls sit on rails on each side of the tank carrier. While printing, the tank carrier rails pull the tank walls and the flexible film into tension.Tank carrier rails
Film tensionerA motor pulls outward on the tank side walls to create a taut film surface in the resin tank.Film tensioner
Tank RFID sensorAn RFID sensor at the back of the printer reads the resin tank’s RFID sticker to read data such as the resin type and tank lifetime.Tank RFID sensor
Tank induction sensorAn induction sensor at the back of the printer senses the presence of an inserted resin tank.Tank induction sensor

Optik

ItemDescriptionImage
Light Processing Units (LPUs)These two interchangeable assemblies contain the lasers and the mirrors that control the path of the lasers, ensuring a clean, crisp laser spot. The LPU housing holds two LPUs.Light Processing Unit
LaserShort for “Light Amplification” via “Stimulated Emission of Radiation.” The lasers are the source of curing energy in the printer with a wavelength of 405 nm, and a maximum output of 250 mW per laser. The Form 3L/Form 3BL is a Class 1 laser product.Laser
Light Processing Unit (LPU) cableA flat, flexible cable connects the LPU to the motherboard.Light Processing Unit cable
Light Processing Unit (LPU) housingThe aluminum housing for the optics engine moves left and right, traveling along the X-axis ball screw. The LPUs, roller holder, and mixer are all controlled within the LPU housing.Light Processing Unit housing
Roller holderThe roller holder is a metal surface that allows for smooth movement of the LPU housing across the flexible film. The roller holder surrounds the glass optical window. A clean roller holder protects the flexible film and preserves print quality.Roller holder
Glass optical windowA narrow piece of anti-reflective coated glass that is surrounded by the roller holder. The glass optical window protects the sensitive mirrors inside the LPUs from dust and other contamination. Maintain a clean glass optical window to prevent print failures.Glass optical window
X-axis ball screwThe X-axis ball screw controls the horizontal motion of the LPU housing.X-axis ball screw
