Custom Parts, Contested Design Files, and Powders That Can Explode.
Protecting service bureaus, additive producers, and the parts they print
Additive-manufacturing service bureaus and producers print polymer and metal prototypes and functional, end-use parts from customer and in-house designs — and their defining risk is a printed part that fails in service when no one can say whether the printer or the customer's file is to blame. Many parts are novel, built to no established standard, and bound for high-severity uses like aerospace, medical, and automotive, so product liability and professional exposure run together. Add hazardous materials — reactive metal powders that can ignite or explode, and photopolymer resins that sensitize skin — and a 3D-printing business needs coverage built around product failure, design responsibility, and material hazard. This is a specialized corner of manufacturing insurance built for how additive makers actually get sued.
Properly structured coverage protects the shop, its people, and the parts it prints.
The Additive Manufacturer's Signature Exposures
Product and professional exposure are the twin defining risks, and they are hard to separate. A printed functional part that fails can cause injury and a product-liability claim, but the fight usually turns on design responsibility — whether the defect lives in the customer's file or in how the bureau printed, oriented, or validated it — which pulls professional and technology E&O into the center of the claim alongside product liability. Material hazard is the second exposure: fine metal powders used in laser and electron-beam systems are combustible and can trigger primary and secondary explosions without inert handling and dust control, and photopolymer resins cause chemical and skin exposure. High-severity end use, inconsistent part quality or inadequate validation, intellectual-property infringement from printing others' files, and the cybersecurity of the design files themselves round out a risk profile unlike traditional manufacturing.
Key Risks in 3D Printing & Additive Manufacturing
Additive manufacturers face exposure related to:
A printed functional part failing in service, with the design-responsibility question — printer versus customer file — driving the claim
A metal-powder combustible-dust fire or explosion
Photopolymer-resin chemical and skin exposure
Intellectual-property infringement from printing others' files
High-severity end use in aerospace, medical, automotive, or structural parts
Inconsistent part quality or inadequate validation
Cybersecurity of design files and production data
The failed custom part and the design-responsibility question are what most define the business.
Core Coverages for Additive Manufacturers
A properly built additive program typically includes:
Product Liability & Completed Operations — Covers printed functional and end-use parts that fail after delivery — frequently the most consequential coverage for high-severity work.
Professional / Technology E&O — Responds to the design-and-file question, covering alleged defects in design, orientation, validation, or the printing process itself.
Commercial Property — Covers the building and equipment against a metal-powder or resin fire.
Equipment Breakdown — Repairs or replaces printers, lasers, and support systems after sudden mechanical or electrical failure.
General Liability — Covers premises and ongoing operations exposure.
Cyber — Addresses breach, theft, or corruption of design files and intellectual property.
Pollution Liability — Addresses reactive-powder and resin releases and waste handling.
Workers' Compensation — Provides legally required coverage for powder, resin, and machinery injuries.
Umbrella / Excess Liability — Adds higher limits above the primary program given end-use severity.
What's Commonly Overlooked
Additive programs are most often weakened by:
No professional / technology E&O, leaving the design-and-file dispute uncovered
Product-liability limits too low for aerospace, medical, or structural end use
No cyber coverage for stolen or corrupted design files and IP
No pollution or special property treatment for reactive metal powders
No contractual allocation of design responsibility between bureau and customer
The gap that hurts most is missing E&O when the claim turns on who owned the design defect.
Real-World Claim Examples
A printed bracket fails in service and the customer and bureau dispute whether the file or the print was defective
Metal powder ignites during handling and causes a flash fire or explosion
A worker develops dermatitis from repeated photopolymer-resin exposure
A customer alleges the bureau printed a part from an infringing or stolen file
A design-file breach exposes a customer's proprietary geometry
Any one of these can be severe, and an end-use failure with contested design responsibility can reach seven figures.
Regulatory & Safety Context
Regulation of additive manufacturing is still emerging and largely flows through end use. OSHA addresses combustible metal dust through the general-duty clause and hazard communication, with inert handling and dust control expected for reactive powders, and end-use regulation passes through to the part — the FAA for aerospace components, the FDA for medical devices and implants — so a bureau serving those sectors inherits their compliance weight. Voluntary ASTM and ISO additive-manufacturing standards increasingly define acceptable process and validation, and intellectual-property law governs the files that drive every build.
Why Proper Placement Matters
Underwriters weigh revenue, polymer versus metal work, the end use of parts (aerospace, medical, and structural rate highest), the split between prototyping and functional end-use production, validation and quality systems, powder and resin handling, and loss history — and they look hard at whether design responsibility is allocated by contract and whether E&O sits alongside product liability. This is predominantly an excess-and-surplus-lines class: end use and metal additive work drive it, the design-responsibility question is central, and admitted markets are limited. Placing the account well, and presenting the controls and contracts, is what makes the coverage respond.
Our Approach
At Cory Washington & Co., we insure additive manufacturers around product failure, design responsibility, and material hazard. We pair product liability with professional and technology E&O so the design-and-file dispute is covered, size limits to your end use, and add property, equipment breakdown, cyber, pollution, and umbrella into one program placed with specialty markets — while helping you allocate design responsibility by contract. We also structure product liability and product recall and contamination coverage for the parts you print and cyber coverage for the files behind them, within the broader manufacturing category.
When a custom part fails and no one agrees whose design it was, product and professional coverage together are everything — we build them to respond as one.

Frequently Asked Questions
How do I get 3d printing & additive manufacturing insurance through Cory Washington & Co.?
Request a quote or contact our team. We start with a short conversation about your operations, analyze your exposures, then negotiate 3d printing & additive manufacturing insurance across multiple carriers that compete for your account and present options with the trade-offs explained. Cory Washington & Co. LLC is licensed in all 50 states.
What does 3d printing & additive manufacturing insurance cost?
It depends on your exposure. 3d printing & additive manufacturing insurance is priced on factors like your industry, size, prior claims, and the limits and deductibles you select — so two businesses rarely pay the same. We shop your account across competing carriers and present the trade-offs in plain English.
Is 3d printing & additive manufacturing insurance required?
Whether 3d printing & additive manufacturing insurance is strictly required depends on your state, your contracts, and your lenders or clients. Even where it is not mandatory, going without it can leave serious financial gaps. We assess your exposure and any contractual requirements, then structure coverage that meets both.
