INDUSTRIAL 3D PRINTING · DESIGN + PRODUCTION
Spark & Spool Co designs and produces industrial FDM and resin parts—from first articles and functional prototypes to controlled short runs and repeat supply. Restore an unavailable part, develop a new solution, or supply an approved part repeatedly.
MORE THAN A PRINTED PART
Spark & Spool turns incomplete part information into a defined requirement, a physically proven result, complete quoted delivery, and a controlled basis for the next order.
01
Bring a print-ready file, drawing, existing or damaged part, photograph, measurements, partial design, or a clearly described problem. Spark reviews the application, identifies missing information, and defines the next practical step. Requests receive a same-business-day acknowledgment during posted hours and an initial suitability response within one business day.
02
Define the fit, finish, function, dimensions, appearance, hardware, count, packaging, and other agreed checks that matter. Industrial and engineering experience guides material, process, design, or reverse engineering where needed. New production work begins with a physical first article and an agreed acceptance basis before repeat production.
03
When included in the quoted scope, Spark can source hardware, install inserts, perform bounded secondary operations, finish, label, kit, lightly assemble, bag, pack, and arrange delivery around the printed part. Local pickup or hand delivery may be available in Greater Cincinnati and Northern Kentucky when practical and included in the quoted scope.
04
After approval, Spark can retain the file and revision, material, process, orientation, color configuration, hardware, finish, labels, packaging, agreed checks, quantity, and repeat-order history needed to quote and reproduce later orders more efficiently. Retention does not promise permanent storage, unchanged pricing, material availability, identical equipment, or automatic production without review.
05
A reorder begins with the established part record. A consequential change to fit, function, geometry, material, process, finish, hardware, packaging, or acceptance needs creates a new review or revision boundary. A successful first project can also make the next part number, related component, kit, variation, recurring need, or awkward application easier to begin.
Acknowledgment is not a quote, engineering approval, order, or production authorization. Complete-Part work and local delivery are included only when suitable and quoted.
Solve the first part well enough that bringing the next problem is easier.
Review Complete-Part DeliveryThree ways to start
Choose the starting point that matches what you have today. Every path receives human technical review; design, reverse engineering, file repair, and production are scoped and quoted as applicable.
Print from File
What to bring: Send the file with intended use, quantity, timing, color, finish, material preference, and the fit or acceptance information that matters.
Spark reviews geometry, material, quantity, timing, color, finish, and intended use, then quotes production. The $200 concept-to-print starting level applies only if design or file repair is separately needed.
Send a print-ready fileDesign the Part
What to bring: Send the existing part, dimensions, drawing, photograph, damaged sample, mating interfaces, intended use, and the result the part needs to achieve.
Reverse engineering, modeling, file creation or repair, iteration, and production are scoped and quoted separately.
Start with the part or problemBring the Idea
What to bring: Share the idea, intended result, important interfaces, measurements, timing, and any files or images you own or have authority to use and share.
Spark provides human geometry, rights, manufacturability, and safety review for a scoped concept-to-print project. Nothing is automatically generated, interpreted, qualified, or repaired by AI.
Explore concept-to-printApplications
From one functional component to a controlled repeat program, the application drives geometry, material, process, finish, acceptance, and delivery.
Brackets, mounts, housings, guards, covers, flexible interfaces, fit checks, detailed prototypes, and compact precision geometry.
Jigs, nests, fixtures, sensor mounts, cable protection, wear guides, organizers, trays, labels, and production aids.
Obsolete plastic components, noncritical replacements, accessories, enclosures, protective parts, and purpose-built interfaces.
First articles, overflow quantities, short runs, repeat batches, dedicated-capacity programs, kitting, and light assembly.
Detailed service routes
Fit-check models, assembly trials, housings, brackets, ergonomic and inspection models before repeat production.
Assembly jigs, drill guides, locating and inspection fixtures, holders, trays, and by-project guards.
Obsolete covers, housings, controls, adapters, retainers, and low-quantity components reviewed for suitability.
Repeat brackets, mounts, covers, holders, flexible features, and controlled part sets from an accepted basis.
Printed, finished, labeled, and packed with approved hardware, bounded operations, kitting, light assembly, project records, and repeat supply as quoted.
Custom machinery, equipment, and component cutaway models for sales, trade shows, training, launches, and display.
Large-format FDM + fine-detail resin
Machine selection follows geometry, environment, finish, quantity, intended use, and the acceptance basis that matters.
Large-format FDM
Current in-house FDM envelope — 350 × 350 × 350 mm.
Larger parts, functional prototypes, fixtures, mounts, brackets, guides, covers, housings, flexible interfaces, controlled short runs, overflow quantities, and repeat supply.
Fine-detail resin
Current resin process resolution — 52 µm XY.
Compact precision geometry, detailed prototypes, inspection models, mechanical cutaways, clear visual models, masters, small interfaces, and specialty resin applications.
Materials & Applications
Materials are selected around the application—not presented as shelf inventory. Any compatible FDM or resin material can be sourced for the job.
Tough · low warp · rigid · reinforced
Functional parts, fixtures, housings, guards, brackets, larger geometry, production aids, moisture-exposed components, and controlled short runs. Carbon-fiber grades add stiffness and a technical surface finish.
Flexible · resilient · protective
Grips, grippers, pads, bumpers, boots, cable protection, compliant interfaces, drone components, flexible guards, protective corners, and vibration-isolating parts.
Wear · snap fit · low friction · structural
Wear guides, bushings, rollers, gears, clips, snap features, sliding interfaces, tooling, rigid fixtures, durable brackets, and higher-demand machine-side applications.
Outdoor · UV exposed · warmer environments
Outdoor housings, covers, labels, brackets, sun-exposed parts, warmer operating environments, and durable visual components.
Detailed · compact · functional
Compact functional prototypes, detailed housings, fit checks, latches, inspection models, small components, precise interfaces, and presentation parts.
Transparent · inspection · visualization
Transparent covers, inspection models, mechanical cutaways, enclosed-geometry demonstrations, visual fluid paths, flow visualization, and internal-feature inspection.
52 µm XY resolution
Compact precision geometry, masters, inspection models, detailed prototypes, small interfaces, and presentation parts.
Flexible · castable · heat-resistant · ESD · flame-retardant · filled
Compatible 405 nm engineering resin families are selected by application. A material designation does not certify the completed printed part.
Rigid, flexible, reinforced, outdoor, clear, precision, and specialty materials. Exact material, grade, color, finish, and process are selected around the part and intended result.
Qualified multicolor FDM
Standard multicolor FDM supports up to four discrete filament colors, subject to geometry, material compatibility, purge requirements, support strategy, surface requirements, schedule, and project economics.
Standard capability
Color matching is approximate and depends on material, vendor, and lot unless a quote defines a controlled sample and acceptance method.
Expanded projects
Not photographic full-color. Geometry, material compatibility, purge/waste, support strategy, schedule, installed and qualified CFS capacity, and test results determine feasibility. Capacity beyond four colors is installed, configured, and qualified before a production commitment.
Responsible project screening
Spark & Spool does not accept safety-critical, medical, weapon-related, pressure-containing, or vehicle lifting, braking, steering, restraint, or similarly failure-critical applications.
