Accura Patch Chemical Safety


Accura® Patch has been designed for, and tested with, 3D Systems’ SLA materials. Safety Datasheets (SDS) may be found at

Safety_Glasses.jpg    Exposure may cause eye damage. Wear UV eye protection.
Safety_Gloves-01.png   WEAR GLOVES: Wear the appropriate gloves when required. For example, when touching surfaces that may contain or have been exposed to materials, wear nitrile gloves.



The photopolymers used in stereolithography may be hazardous if handled improperly. Repeated skin contact with materials may cause sensitization. Consult the manufacturer’s Safety Data Sheet (SDS) for information on specific materials. For further information on this and related topics, consult the 3D Systems – Materials website at


The material syringes are packaged in sealed shipping bags . Upon receipt of material shipments, inspect bag exterior for signs of damage and leakage. If leakage is observed, DO NOT open bag, and contact 3D Systems’s Technical Support Hotline.

Prior to actual use of Accura® Patch material, read the Safety Data Sheet (SDS). Follow the instructions and guidelines in which that document provides.

Accura® Patch material should be stored in the black, non-reactive syringes in which they were provided, according to the guidelines given in the SDS included with the print material and all applicable regulations (local, state, and federal).

Protect Accura® Bond material from sunlight and ambient room light. Accura® Bond is composed of reactive monomers and oligomers. If improperly stored or handled, these compositions may undergo polymerization resulting in the emission of heat.

Improperly stored material may increase in viscosity, and eventually result in a gelled, polymerized product in the storage container. Materials should be stored in conformance with applicable laws and regulations. 3D Systems is not responsible for losses incurred as the result of improper storage of print material. See subjects of Light and Temperature below.


Photocurable materials should be shielded from sunlight or other sources of actinic radiation such as fluorescent or mercury vapor lights. Exposure to UV radiation leads to an increase in product viscosity and eventually to product polymerization, rendering the material unusable for part printing.

Containers of Accura® Bond material should be kept indoors at temperatures between 16 ºC (60 ºF) and 27 ºC (80 ºF). Temperatures above 27 ºC (80 ºF) may accelerate the depletion of the stabilizers contained in the product. Once the stabilizers are exhausted, the product may undergo polymerization, rendering it unusable for part printing.

Shelf Life
Accura® Bond material is certified for use at least 24 months from its date of manufacture.

Signs of polymerization of stored material include container bulging, leaking, and the emission of heat, or an unusual odor from the container. If you notice this, do not use the material and dispose of it properly.

Because stereolithography materials are regulated, they are subject to special disposal requirements by your local, federal, or other regulatory agencies. Follow applicable disposal guidelines. Contact a local waste management company for recommendations on disposal requirements that affect your facility.

Do not leave uncured or liquid materials in an area where persons who are not knowledgeable about their handling or use may have access to them. If your area requires regulated waste disposal, consult with and retain a waste management company to periodically pick up regulated waste. Your local waste management company may recommend that you set up a drum, or other approved container, to dispose of liquid print material and of any materials (such as paper towels or gloves) that may have come into contact with the uncured liquid print material.



The following paragraphs provide general first aid procedures and recommendations for protective equipment to minimize the risks from material exposure. If professional medical attention is necessary, take the Safety Data Sheet (SDS) for the exact material involved to the attending physician.
