Functional prototypes
Physical parts for fit checks, assembly trials, design iteration, and hands-on evaluation before committing to a larger production method.
Greater Cincinnati + Northern Kentucky
Industrial parts, printed with an engineer's eye.
Practical support for functional prototypes, jigs and fixtures, non-safety-critical replacement parts, and controlled low-volume production.
Engineering-led. Partnership-focused. Built locally.
Built for local industry
Supporting machine shops, maintenance teams, automation builders, labs, and small manufacturers with short-run parts that need care, context, and clear expectations.
Capabilities
From one useful part to a controlled short run.
Start with the application, not the printer. We review the use, material, geometry, quantity, and acceptance criteria before a job is quoted.
Jigs & fixtures
Simple workholding aids, guides, templates, organizers, and repeatable shop-floor tools shaped around the task.
Replacement parts
Authorized recreation of non-safety-critical covers, knobs, spacers, brackets, and other difficult-to-source plastic parts.
Low-volume production
Controlled batches for teams that need predictable replenishment without the tooling commitment of mass production.
Production options
FDM strength and flexibility. Resin detail when it matters.
Material and process selection follows the actual environment and function of the part. Final suitability is confirmed during the application review.
PETG
Durable general-purpose parts and shop applications.
PLA variants
Fast, clean prototypes, models, organizers, and fixtures.
TPU / TPU-GF
Flexible parts, pads, grips, and resilient functional geometry.
ABS-like resin
Fine features and high-detail parts with crisp presentation.
How it works
A clear path from problem to part.
- 1
Share the application
Send the file, drawing, photo, dimensions, quantity, deadline, and a plain-language description of how the part will be used.
- 2
Review & quote
We screen the application, confirm assumptions, and provide a practical scope for engineering, setup, material, and production.
- 3
Approve a pilot
When fit or function matters, start with a paid pilot part and agree on the acceptance criteria before scaling the quantity.
- 4
Schedule production
Approved work moves into a controlled batch plan with clear timing, inspection expectations, and delivery arrangements.
Responsible application screening
Some parts should not be 3D printed by a small job shop.
Spark & Spool Co does not accept safety-critical, medical, weapon-related, pressure-containing, vehicle lifting, braking, steering, restraint, or similarly failure-critical applications. If the intended use is unclear, we will ask before quoting.
Local and accountable
Work directly with the person reviewing and producing the part.
Spark & Spool Co is an engineering-led industrial 3D printing shop based in Erlanger, Kentucky. Sergey Korchagin, Lead Engineer / Owner, handles application review, quoting, production planning, and customer communication.
The shop is intentionally focused on practical low-volume work and ongoing local production relationships—not anonymous, high-volume click-to-print orders.
Start with the problem
Have a part in mind?
Send what you have. A CAD file is helpful, but a drawing, photo, measurements, and description of the use are enough to start a practical conversation.
