Functional Prototypes, Fit Checks & Design Iteration
Fit-check models, assembly trials, housings, brackets, ergonomic and inspection models before repeat production.
3D-Printed Jigs, Fixtures, Guards & Production Aids
Assembly jigs, drill guides, locating and inspection fixtures, holders, trays, custom part carriers and nests, and by-project guards.
Obsolete & Replacement Plastic Parts
Obsolete covers, housings, controls, adapters, retainers, and low-quantity components reviewed for suitability.
Low-Volume Functional Plastic Parts & Repeat Supply
Repeat brackets, mounts, covers, holders, flexible features, and controlled part sets from an accepted basis.
Complete-Part Delivery
Printed, finished, labeled, and packed with approved hardware, bounded operations, kitting, light assembly, project records, and repeat supply as quoted.
Flagship Scale Models
Custom machinery, equipment, and component cutaway models for sales, trade shows, training, launches, and display.
MORE THAN A PRINTED PART
From the first question to the next order.
Agree the job before manufacturing, check the first article, and keep a clear basis for repeat work.
Start with what you have.
Send a CAD file, drawing, sample, photo, or short description. We review the application and identify what is needed before quoting.
Agree what needs to fit, function, and look right.
Define the dimensions, interfaces, finish and checks that matter. Design and development are scoped separately; new production work begins with a quoted first article.
Deliver the quoted result.
Finishing, hardware, inserts, labels, kitting, light assembly and packing are included when agreed and quoted. Local pickup or hand delivery may be available when practical.
Keep the approved design and setup for reorders.
Retain the approved file, material, process, finish and agreed checks so later orders can start from a known basis.
Review changes before the next batch.
Changes to fit, function, geometry, material, process, hardware, finish or packaging need review before production. Bring related parts and repeat needs with the same application context.
What we retain for repeat orders
The approved record may include file and revision, material, process, orientation, color configuration, hardware, finish, labels, packaging, agreed checks, quantity and order history. Retention does not promise permanent storage, unchanged pricing, material availability, identical equipment or automatic production without review.
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 DeliveryLarge-format FDM + fine-detail resin
The part determines the process.
Machine selection follows geometry, environment, finish, quantity, intended use, and the acceptance basis that matters.
Large-format FDM
Functional, durable, flexible, and reinforced parts.
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
Compact geometry and detailed visible features.
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
Rigid, flexible, reinforced, outdoor, clear, precision, and specialty materials.
Materials are selected around the application—not presented as shelf inventory. Any compatible FDM or resin material can be sourced for the job.
PETG / PETG-CF
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.
TPU / TPU-GF
Flexible · resilient · protective
Grips, grippers, pads, bumpers, boots, cable protection, compliant interfaces, drone components, flexible guards, protective corners, and vibration-isolating parts.
Nylon / PA + engineering composites
Application review · grade and process to be confirmed
Custom adapters, product guides, gripper contact parts, assembly nests, and changeover components are reviewed by application. Material and first-article qualification precede production commitments.
Review custom nylon applicationsASA / ABS
Outdoor · UV exposed · warmer environments
Outdoor housings, covers, labels, brackets, sun-exposed parts, warmer operating environments, and durable visual components.
Tough / ABS-like resin
Detailed · compact · functional
Compact functional prototypes, detailed housings, fit checks, latches, inspection models, small components, precise interfaces, and presentation parts.
Clear resin
Transparent · inspection · visualization
Transparent covers, inspection models, mechanical cutaways, enclosed-geometry demonstrations, visual fluid paths, flow visualization, and internal-feature inspection.
Precision / detail resin
52 µm XY resolution
Compact precision geometry, masters, inspection models, detailed prototypes, small interfaces, and presentation parts.
Specialty resin
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
Discrete filament colors, reviewed by project.
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
Up to four discrete filament colors.
Color matching is approximate and depends on material, vendor, and lot unless a quote defines a controlled sample and acceptance method.
Expanded projects
Up to 16 discrete filament colors where feasible and quoted.
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.
Finishing & delivery
The complete job, as quoted.
Hardware, inserts, secondary operations, finishing, labels, kitting, light assembly and packing can be included when suitable. Local pickup or hand delivery may be available when practical and quoted. Specialty finishing and delivery are separately scoped.

Responsible project screening
Strong parts begin with the right manufacturing path.
Spark & Spool does not accept safety-critical, medical, weapon-related, pressure-containing, or vehicle lifting, braking, steering, restraint, or similarly failure-critical applications.
