Capstone Design
Capstone Design Prototyping
Capstone design prototypes from idea consulting and 3D modeling to 3D printing and finishing in one place. Quotes, transaction statements, and tax invoices available for university research-foundation payments.
Quick answer
Capstone design prototypes follow idea consulting → 3D modeling (outsourced if needed) → quote and order → printing and finishing → delivery, and we issue the quotes, statements and tax invoices universities need for payment. Printing alone takes 3–7 days on average, but start 3–4 weeks before the final presentation if modeling and a first prototype revision are included.

Schedule
Recommended schedule, counted back from presentation day
Leaving time to check size, fit, and motion with a first prototype greatly reduces last-minute fixes.

Frequently asked questions
QHow does capstone prototyping work?
Idea consulting → 3D modeling (we can model for you) → quote & order → printing & finishing → inspection & delivery. If you already have a 3D file, get a price instantly in auto-quote.
QCan you build a capstone prototype from just an idea?
Yes. Through idea consulting we define structure, size, material, and process together, then model from your sketches or reference images and print.
QDo you issue documents for university research-foundation payments?
Yes. We can issue quotes, transaction statements, and tax invoices. Tell us which documents you need and the billing details when you contact us.
QHow much does a capstone prototype cost?
It depends on size, material, print method, quantity, and finishing. With a 3D file you can check instantly in auto-quote; when consulting or modeling is included, we send a quote after consultation.
QHow much lead time should I leave before the presentation?
Printing alone typically arrives in about 3–7 days. Including modeling and a first-round revision, start 3–4 weeks before the final presentation. If the schedule is tight, contact us first to check feasibility.
QWhich materials suit a moving functional prototype?
FDM PETG or ABS for parts that need assembly, fastening, or durability; SLA/DLP resin for presentation surfaces and fine detail. Processes and materials can be mixed per part.
QCan you make enclosures for Arduino or other electronics?
Yes. Share board, sensor, and battery dimensions and we model the fastening and fit clearances before printing. If you design it yourself, see the tolerance guide for fit allowances.
QOur team has many files — can we order them together?
Yes. Add all files to the cart and order at once; files using the same print method and material share a single minimum order charge (each different material has its own).
