Robotics 3D Printing Service: End of Arm Tooling and Custom Mounts

3D print the parts that change often or need a custom shape: end effectors and grippers, sensor and camera mounts, cable guides and clips, small enclosures, and jigs and fixtures for the cell. These are the parts you tweak between builds, so printing them beats waiting weeks for machined metal.

End of arm tooling, or EOAT, is the part the robot uses to grip, push, or sense. Common jobs are parallel gripper jaws, suction cup mounts, pick-and-place fingers, and sensor brackets. Cable management and small covers round out most robotics orders. If your robot needs a custom part for a specific job, we will print it.

Most robot parts need to bolt to something. We can print clearance holes for bolts, pockets for heat-set threaded inserts, and slots for cable ties. Tell us the hardware you use and we size the holes to fit, so that the part drops onto the robot without drilling or filing on your side.

Three materials cover most robot parts. PA-CF is the workhorse for structural EOAT, since it is stiff enough to hold tolerance under repeated load and light enough not to slow the arm. TPU is the pick for grippers that touch the part, since a soft pad grips without scratching. PETG is the budget pick for mounts and guards that do not see heavy load.

PA-CF reaches about 80 MPa tensile strength and holds its shape up to about 140 C, so it keeps tolerance near motors and hot tools. TPU bends and springs back, so a gripper pad conforms to an odd shape and lets go clean. See specs at PA-CF, TPU, and PETG.

You can hold the next version in a few days. Robotics teams iterate hard on grippers. Print the first one, test it, find the angle is off, and print v2. Each version ships in 2 to 5 days, so a week of testing can cover two or three tries. Most teams reach a working gripper in three to six rounds.

When the gripper works, the same printer and the same material print the production run. The part behaves the same from the first sample to the last spare, so you do not re-qualify the design when you scale up. Start with a sample today, then order the run once the design is locked.

Small and large orders both fit. Prototype gripper runs of one to ten units ship in 3 to 5 business days. Spare-part stocks of fifty to two hundred units ship in 5 to 10 business days. Larger fleet rollouts ship on the standard production timeline, and the price per part drops as the count grows.

See prototype printing and production runs for the full tier breakdown.

These examples show typical jobs, not named customers.

A warehouse automation team orders fifty PA-CF gripper jaws each quarter. Same file, same material, same price each time, so a reorder takes three clicks.

A cobot team iterates a new sensor mount through five versions. Each version ships in a few business days, and the team commits to the design only after the fifth one passes the test.
