Form 2 3D Printer by formlabs on Sketchfab

Before viewing the notations in the 3D model, play the “Disassembly” animation (click on "Static Pose" if the animation is not already playing). Press the "Pause" button at any time. Drag the slider on the bottom of the window to skip to any point. Notations on the model will work best at the end of the animation.

External Components

Item Description Image
Shell This metal covering protects the printer's internal components. It is made from two pieces.  Shell.JPG
Leveling Feet Each 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 tool to raise or lower each foot to ensure that the printer is acceptably level.  levelingfeet.jpg

Display Assembly

Item Description Image
Touchscreen The LCD displays print information, settings, and error messages. It serves as the user interface for the Form 2. LCDtouchscreen.jpg
Display PCB This circuit board, separated from the main motherboard, controls the touchscreen.  displayPCB.jpg
Ribbon Cable This cable connects the touchscreen to the motherboard. ribboncable.JPG
Push Button The button starts and pauses prints when prompted by the touchscreen. Hold the button to wake and sleep the printer.  pushbutton.jpg

Amber Cover

 Item Description Image
Amber Cover The cover is injection molded from high impact strength polycarbonate. It is tinted amber to block exposure to the laser and to protect the resin from curing due to ambient UV light.  ambercover.jpg
Latch Magnets  The latch magnets secure the amber cover in place.  latchmagnets.jpg
Interlock Magnets  The 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 laser when the cover is open.   interlockmagnets.jpg


Item Description Image
Cartridge This container holds the resin before dispensing into the resin tank. Shake the cartridge periodically to keep resin well mixed.  cartridge.jpg
Vent Cap  The lid at the top of the cartridge allows for air interchange, so that resin dispenses properly. The vent cap must be pushed open prior to printing. ventcap.jpg
Cartridge ID Chip  An Electrically Erasable Programmable Read-Only Memory (EEPROM) chip is attached to the cartridge skirt and is programmed with the resin type. This chip communicates to the printer via spring fingers on the cartridge floor. cartridgeIDchip.jpg
Bite Valve This silicone seal regulates resin dispensing. Resin flows out when the cartridge dispense arm squeezes the valve open. bitevalve.jpg

Cartridge Floor Assembly

Item Description Image
Cartridge Spring Fingers  Two 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 cartridge.  cartridgespringfingeres.JPG
Cartridge Dispense Arm  This plastic hook presses against the bite valve to dispense resin out of the cartridge into the resin tank.  cartridgearm.JPG


Item Description Image
Z Tower  This vertical tower at the back of the printer provides support for many parts of the Form 2. The build platform is raised and lowered along the Z-axis, inside the tower. The Z Tower also encloses the resin cartridge and the mechanisms for dispensing the resin into the tank. ztower.jpg
Lead Screw  The lead screw is a threaded rod that controls the vertical motion of the build platform carriage. leadscrew.jpg
Z-Axis Limit Switch  This optical sensor tells the motor driver when the build platform has reached the top of the tower. zaxislimitswitch.jpg

Build Platform

Item Description Image
Build Platform  The aluminum base provides a surface for prints to attach to. Over time, the build platform will develop scratches from part removal, which can assist with print adherence.  buildplatform.jpg
Cam Handle  This lever is part of the locking mechanism that secures the build platform. Raise the cam handle before inserting the build platform, and lower the cam handle to lock the platform into place. camhandle.jpg
Build Platform Carriage  The carriage is the metal arm that the build platform slides onto. bpcarriage.jpg
Cam Lock Spring  The spring mechanism inside the build platform carriage allows the cam handle to move up and down. It also mechanically locks and unlocks the build platform. camlockspring.jpg
Cam Lock Set Screws (x3)  These three screws are used for adjusting the tension in the cam lock. We advise contacting Support before adjusting these screws, as improper adjustment can lead to damage to the machine.  camlocksetscrews.jpg

Resin Tank

Item Description Image
Resin Tank  The polycarbonate resin tank is the primary container for holding resin after it is dispensed from the cartridge. Resin is cured onto the build platform when the laser passes through the tank's acrylic plastic window. Only use approved chemicals and processes to clean the resin tank. resintank.jpg
Tank Grips  Plastic handles on each side of the resin tank help to more easily insert, remove, and carry the tank. Avoid touching the bottom of the resin tank, as fingerprints can leave smudges that obstruct the optical path.  tankgrips.jpg
Tank Spout  This spout at the back of the resin tank sits underneath the cartridge dispense hole and receives resin from the cartridge.  tankspout.jpg
Silicone Layer A coating of optical silicone (also called PDMS) on the bottom of the tank enables a smooth peeling process. Over time this material will cloud from printing, and eventually the tank must be replaced.  siliconelayer.jpg
Resin Tank ID Chip  The resin tank's ID chip uses Electrically Erasable Programmable Read-Only Memory (EEPROM). The tank spring fingers read the chip to detect the unique tank ID and current resin type. tankIDchip.jpg
Wiper  Each resin tank includes a wiper. The wiper improves print consistency by clearing the build area after each layer and circulating the resin. Tankwiper.jpg
Insertion Foot  The insertion foot is located on the bottom of the wiper and holds the wiper to the wiper mount. insertionfoot.jpg
Wiper Mount  The wiper mount connects the wiper to the belt drive system. Insert the wiper's insertion foot into the metal bracket before printing. wipermount.jpg

Optical Window

Item Description Image
Optical Window  Located underneath the resin tank, the optical window is a glass plate with an anti-reflective coating. It protects the sensitive mirrors inside the printer from dust and other contamination. Maintain a clean optical window to prevent print failures. opticalwindow.jpg

Tank Carrier

Item Description Image
Tank Carrier  The tank carrier holds the resin tank and slides left and right during the peel process. Each printer's alignment is uniquely calibrated at the factory. Any change to this alignment via unscrewing or tampering may cause print issues that can only be resolved by a return for re-calibration. traycarrier.jpg
Shuttle Cover  The shuttle cover protects the interior of the printer from spilled resin. It can catch up to 50 mL of resin in the trough located at the front, just under the printer's shell. shuttlecover.jpg
Tank Spring Fingers  These electrical contacts are embedded in the tank carrier. They read the resin tank's EEPROM ID chip to sense the tank's presence and to communicate the resin type to PreForm.  springfingers.jpg


Item Description Image
Motherboard  The motherboard is the main circuitry through which all systems in the printer communicate. motherboard.jpg
Power Supply The Form 2 utilizes a 100–240 V power supply. The internal power supply converts line power to +24V DC. powersupply.jpg
Motor Drivers  Located on the motherboard, these three small chips control the three stepper motors in the machine (build platform, wiper, and tank carrier). Each driver connects to its motor via the cable socket directly in front of the chip. motordrivers.jpg
To Front Display (Connector)  This connector links the display to the motherboard via a ribbon cable. ribbonplug.jpg
Wi-Fi Antenna The Wi-Fi antenna enables the Form 2's wireless connectivity. The antenna pokes through a hole on the printer's motherboard. wifi.jpg
Ethernet Port The Form 2 can connect to a network via Ethernet. The port is connected to the motherboard and can be accessed from the back of the machine. ethernet.jpg
USB Port The Form 2 can connect to a computer via USB. The port is connected to the motherboard and can be accessed from the back of the machine. USB.jpg

Wiper Actuator

Item Description Image
Wiper Belt This geared rubber belt connects the wiper mount to the wiper motor. As the motor turns, the belt moves the wiper back and forth across the resin tank. slidebelt.jpg


Item Description Image
LevelSense Board

The black panel behind the resin tank measures and regulates the refill rate of the resi
