Custom gripper fingers and vacuum plates for robot integrators in a week
TL;DR Gripwright designs and prints the bit of a robot that actually touches the product - custom fingers, vacuum plates and mounting adapters. Robot system integrators and plant automation teams send in a part sample and get tested tooling back within a week. They pay per design and per set, and reorder spares from a stored file.
India installed 10,500 industrial robots in 2025, up 15% on the year before[1]. Every one of them needs a tool at the end of the arm shaped for the exact part it handles, and that tool is usually the last thing anyone designs and the first thing that holds up commissioning.
Catalogue grippers come with standard or lightly customisable fingertips[2]. So an integrator handling an odd casting or a soft pouch ends up getting fingers machined at a local job shop, by trial and error. General print bureaus can make the part but they don't design grippers or test grip[3]. The result? Weeks of delay on a project worth lakhs, and spare fingers that nobody kept a drawing for.
Gripwright is a design-and-make service with a library behind it. An integrator uploads the part's CAD or posts a sample, along with the robot model and the gripper body they use. Gripwright's engineers design fingers or a vacuum plate, print them in tough nylon or flexible TPU, test them on a matching gripper with the real part and ship in five to seven working days.
Every design goes into the customer's account, so a worn finger can be reordered in two days without new drawings. Over time the library of proven shapes for common Indian parts like castings, pouches, bottles and auto components makes each new job faster.
Cost isn't the barrier here. An open-source gripper paper lists its printed finger parts at about US$1.50 (around ₹145) in material[4]. What customers really pay for is design skill and speed.
The main buyers are robot system integrators, who pass tooling costs into their project price, and in-house automation teams at auto-component, packaging and electronics plants. Today they pay job shops for machined fingers or the gripper maker for spares. There's no public price for custom fingers in India, so test a design fee plus a per-set charge against what integrators spend on machined fingers now.
Robot installs in India grew by an average of 27% a year from 2020 to 2025[1], so integrators are busier and shorter on design time. Industrial printing in nylon and TPU is easy to get from Indian bureaus[3], and one German plastics maker's Indian arm sells low-cost automation alongside its own print service[5].
We found no public figure for end-of-arm tooling in India. The best count is bottom-up - 10,500 new industrial robots in 2025[1], each with at least one tool set and spares over its life. Robot makers also sell through Indian partners, like one cobot maker with a machine-tool distributor that runs 10 technical centres in India[6]. Those partners are your first customers.
A Danish gripper maker sells catalogue grippers with customisable fingertips but describes no custom design service[2]. A Hyderabad print bureau prints in nylon, resin and metal but doesn't mention grippers[3]. The German plastics maker offers a 3D printing service next to its low-cost robots[5]. None of them sells grip-tested custom tooling with a stored design library, and that's the gap.

The printing is capacity you buy. The hard part is design judgement, which means knowing how a finger flexes, wears and slips at real cycle speeds. Integrators will trust you only after a few jobs work first time, and each job is small, so quoting and design have to take hours rather than days.
No special licence applies, as far as we found. Gripper fingers are parts sold to an integrator, who carries the cell's safety design.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't trust a simulated grip as proof. Every design still needs a physical test with the real part before it ships.

I like this as a capital-light start for a mechanical engineer who has commissioned robot cells and knows integrators personally. It's a weak fit for a pure 3D-printing shop with no grip know-how. Prove first that ten integrators send a second job within 60 days of their first.
About ₹45–80 L covers industrial printers, a test bench with a gripper and a small design team. It's one of the lighter-capital ideas in robotics.
No sector licence. You need company registration, GST and safety compliance for any robot test bench on your own premises.
Yes, integrators everywhere face the same last-minute tooling crunch. Local product liability and design-ownership terms are what to check.

Thinking about building Gripwright or something close to it? The make-or-break work is getting the first ten designs to grip right on the first try, and I'm happy to think that through with you. If you need a hand, you know where to find me. Talk to Yash →
