Short answer
Export your part as an STL, upload it, and you get a price immediately. Most single project parts cost ₹400–₹2,500: ₹4 per gram of plastic plus ₹1.5 per minute of machine time, then 18% GST and shipping.
Two rules save students the most money and the most marks: drop infill to 15% for anything not carrying load, and order at least two weeks before submission so there is room for one revision.
Why order instead of using the college lab?
Most Indian colleges now have a printer somewhere in the innovation cell or the mechanical department. When it is free and available, use it. It usually is not both. The predictable problems are a queue that gets long exactly at project season, a machine whose calibration has drifted, a lab technician available in a two-hour window, and no help at all when the print fails at 80%.
A service is worth paying for when the deadline is fixed: you get a known price before you commit, a known date, and a reprint if the part comes out wrong. That last point matters more than the cost difference — a failed print three days before submission is a much more expensive problem than ₹800.
What students actually get printed
Across departments, the same shapes come up again and again:
| Field | Typical parts | Usual material |
|---|---|---|
| Robotics / mechatronics | Chassis plates, motor and servo mounts, wheel hubs, gripper jaws, gear sets | PETG |
| Drones / UAV | Arms, motor pods, battery trays, camera mounts, landing gear | PETG |
| Electronics / IoT | Sensor enclosures, PCB standoffs, panel mounts, cable routing clips | PETG |
| Mechanical design | Linkage prototypes, cam and follower rigs, jigs and fixtures, gearbox mock-ups | PETG |
| Architecture / civil | Massing models, terrain sections, façade panels, structural demonstrators | PLA |
| Biomedical | Anatomical study models, splint and brace prototypes, device housings | PLA or PETG |
| Product design | Form models, ergonomic mock-ups, packaging prototypes | PLA |
What does a project part cost?
Two numbers set the price: grams of plastic and minutes of machine time. Real examples at our rates of ₹4/g and ₹1.5/min:
| Part | Weight | Print time | Before GST | With GST |
|---|---|---|---|---|
| Gear set (5 pieces) | 35 g | 2 hr | ₹320 | ₹377.60 |
| Drone arms (set of 4) | 60 g | 3.5 hr | ₹555 | ₹654.90 |
| Sensor enclosure | 80 g | 4 hr | ₹680 | ₹802.40 |
| Robot chassis plate | 120 g | 5 hr | ₹930 | ₹1,097.40 |
| Architecture massing model | 200 g | 9 hr | ₹1,610 | ₹1,899.80 |
| Prosthetic hand demonstrator | 250 g | 14 hr | ₹2,260 | ₹2,666.80 |
Shipping is added at checkout based on your pin code. Your own part will differ — the numbers above assume 15–20% infill and standard 0.2 mm layers — but they are the right order of magnitude for planning a project budget. For an exact figure, upload the STL; the quote costs nothing and needs no account.
Seven ways to cut the cost in half
Students overpay for the same avoidable reasons. In rough order of impact:
PLA or PETG for a project part?
PLA if it is judged by eye, PETG if it is judged by function. PLA holds sharper detail and gives cleaner flat surfaces, which suits architecture models, anatomical models, and form prototypes. It also softens around 60 °C, so a part sitting next to a motor driver or in a car boot will droop.
PETG is tougher, bends before it snaps, and holds up to about 80 °C — the right pick for motor mounts, drone arms, brackets, and any enclosure that gets warm. Both are ₹4/g here, so the choice is purely technical. The full comparison is on the materials page.
Plan backwards from your submission date
Two weeks of clearance is the right target. The reason is not the printing — it is the revision you have not planned for yet. First prints reveal a hole that is 0.4 mm too tight or a mount that fouls a wire, and you want time to fix that once.
| Stage | Time | Note |
|---|---|---|
| Export and upload the STL | 10 min | Price and preview are instant |
| Printing and inspection | 3–5 days | Longer for very large parts |
| Delivery across India | 2–5 days | Tracked, via Delhivery |
| Delivery inside Jaipur | Same day dispatch | Usually hours, not days |
| Buffer for one revision | ~1 week | The step everyone skips |
What to send us
A clean handover avoids a round of emails and a delay:
- An STL exported in millimetres, at fine resolution, as one closed solid rather than loose surfaces.
- The quantity, if it is more than one.
- Which faces matter — mating surfaces, holes that must fit a shaft or a bearing, or a face that must stay smooth.
- Your deadline, stated as a date. It changes how we schedule the print.
One part: upload it on the upload page and order directly. A batch for a team or a whole class: send the file, quantity, and deadline via the contact page and we will send a written quotation for the lot.
Frequently asked questions
How much does it cost to 3D print a college project part in India?
Most single project parts land between Rs 400 and Rs 2,500. Pricing is material plus machine time — at Pookie Prints, Rs 4 per gram of PLA or PETG plus Rs 1.5 per minute of print time, with 18% GST and shipping added at checkout. A sensor enclosure of about 80 g and 4 hours works out to roughly Rs 800 including GST, before shipping; a robot chassis plate of about 120 g and 5 hours is around Rs 1,100.
How can students make 3D printing cheaper?
Five things cut cost fastest: drop infill to 15% for anything non-structural, scale the model down if the size is not fixed, hollow out solid volumes, split large parts so they print flat without supports, and print one prototype at draft layer height before committing to the final version. Between them these routinely halve the price of a project part.
Which material should I use for an engineering project?
Use PLA for display models, architecture massing models, geometry demonstrations, and anything judged on appearance. Use PETG for parts that carry load, get warm, move against each other, or live outdoors — motor mounts, drone arms, brackets, and enclosures near electronics. Both cost Rs 4 per gram, so choosing correctly costs nothing.
How long before my submission should I order a 3D print?
Order at least two weeks before the deadline. Printing and inspection take 3-5 days and delivery 2-5 days, so 7-10 business days is normal across India, and you want slack for one revision. In Jaipur we dispatch the same day, which compresses that considerably.
Can I get multiple copies printed for a group or a class?
Yes. Send the file, the quantity, and the deadline through the contact page and we will send a written quotation for the batch rather than making you order the parts one at a time. Repeat copies of the same part are cheaper per unit than one-offs because the setup is already done.
What file do I need to submit for printing?
An STL exported from your CAD tool — Fusion 360, SolidWorks, CATIA, Creo, Onshape, Tinkercad, and FreeCAD all export STL directly. Export at a fine resolution, keep the model in millimetres, and make sure it is a single closed solid rather than loose surfaces.
