Design engineering and 3D printing services for functional parts.
CAD design support, DFM review, prototypes, replacement components, jigs, fixtures, and low-volume parts built around the way the part actually needs to work.
Quote-ready checklist
- Upload: STL, STEP, OBJ, drawing, sketch, or part photo
- Tell us: quantity, deadline, material needs, load, heat, or fit concerns
- We review: print orientation, material, tolerance risk, and failure points
- You get: clear pricing, lead time, and practical recommendations
For typical files and clear requirements.
Strong option for fixtures, prototypes, and short runs.
Reduce avoidable failures and quote surprises.
Choose the design or manufacturing support that matches the problem.
This page separates design support from printing so customers understand Additive Innovations MFG can help before there is a perfect CAD file.
Rapid Prototyping
Validate fit, form, and function after the design has been reviewed for manufacturability and use case.
Best for: concept models, fit checks, design iterations.
Replacement Parts
Recreate hard-to-source or discontinued plastic parts with geometry and material improvements where needed.
Best for: brackets, covers, clips, guides, housings.
Jigs & Fixtures
Build practical shop-floor aids that improve assembly, inspection, positioning, and repeatability.
Best for: drill guides, holding fixtures, gauges, templates.
Low-Volume Production
Produce short-run parts without committing to molds, outside tooling, or long procurement cycles.
Best for: pilot builds, spare parts, custom batches.
CAD Design & DFM
Create or repair CAD from sketches, measurements, sample parts, or rough files, then prepare geometry for printing or manufacturing.
Best for: weak models, tolerance issues, production-ready files.
Reverse Engineering Support
Use photos, measurements, and sample parts to help recreate geometry for replacement, redesign, or print-ready CAD.
Best for: obsolete parts and undocumented hardware.
Practical design and additive manufacturing support, not mystery quoting.
The goal is not just producing a print. The goal is selecting a process, material, and build strategy that makes sense for the part’s job.
File Types
STL, STEP, OBJ, sketches, drawings, photos with dimensions, and broken part references.
Use Cases
Fixtures, prototypes, replacement parts, brackets, covers, holders, and test pieces.
Design Review
CAD cleanup, wall thickness, orientation, tolerances, heat, load direction, and failure risk.
Finishing Options
Basic support removal, cleanup, fit checks, inserts, and assembly support when applicable.
Material choice should follow the application.
A service page needs this because customers usually know the problem, not the polymer datasheet. This gives them a clearer path before they request a quote.
PLA
Visual prototypes, fit checks, low-stress parts
Lowest cost, fastest option, not for heat or high load.
PETG
Functional prototypes, brackets, covers, utility parts
Good durability and chemical resistance for general use.
ABS / ASA
Tougher parts with better heat resistance
Good for functional parts where environment matters.
TPU
Flexible parts, bumpers, grips, gaskets, protective pads
Flexible behavior depends heavily on geometry.
Nylon / Composites
Stronger functional parts, wear resistance, higher demand uses
Better performance, higher cost, more design constraints.
How design and manufacturing requests are handled.
Same clean look as the new site, but a different page purpose: it explains how design services and 3D printing move from request to quote.
Application Review
We identify what the part needs to survive: fit, load, heat, flexibility, environment, and deadline.
Design / Print Strategy
CAD geometry, missing details, material, layer direction, wall thickness, supports, and tolerance risk are reviewed before production.
Quote + Lead Time
You get clear pricing with practical recommendations instead of a vague “we can print that” response.
Design, Build + Delivery
CAD deliverables and/or printed parts are checked, cleaned up, and prepared for pickup, local delivery, or shipping when available.
What to send so design work or quoting is accurate.
A better quote comes from better inputs. You do not need a perfect engineering package, but the more application detail you provide, the fewer assumptions have to be made.
Files
STL, STEP, OBJ, drawing, sketch, dimensions, or photo of the part.
Quantity
Prototype, one-off replacement, or low-volume batch.
Use Conditions
Load, heat, chemicals, outdoor exposure, flexibility, or fit requirement.
Deadline
Target delivery date and whether speed or cost matters more.
