2 Introduction
2.1 Intended use
The Form 3BL is a commercial, precision tool intended for use in the additive manufacture
of end-user supplied designs from photopolymer resin. The final performance characteristics
of cured photopolymer resin may vary according to your compliance with the instructions
for use, application, operating conditions, material combined with, end use, or other factors.
In some cases, the additive manufacturing process may inherently result in variable
performance characteristics between manufacturing runs or within a specific part.
Such variances may not be apparent and may result in unexpected defects in
additively fabricated parts.
You shall independently verify the suitability of additive manufacturing, stereolithography
(SLA), the Form 3BL, and any specific designs or materials employed for the application
and intended purpose before use. In no event shall Formlabs be liable for any loss,
death, or bodily injury that you suer, or that you cause to any third party, in connection
with your use of Formlabs products. To the fullest extent legally permitted Formlabs
EXPRESSLY DISCLAIMS ANY IMPLIED OR EXPLICIT WARRANTY OF FITNESS for a
particular usage, the particular nature and circumstances of said usage being unforeseen
and unforeseeable to Formlabs.
Formlabs is not a manufacturer of medical devices. Formlabs provides tools and
materials that may be used in many applications, but makes no claims as to the safety or
eectiveness of any specific devices made using Formlabs products. Certain Formlabs
products, such as those commonly known in the industry as “biocompatible” materials,
have been engineered to comply with relevant industry standards. The specific standards
and most relevant technical specifications may be identified within the technical data
sheets and have been tested according to relevant testing protocols for those standards
and specifications. Biocompatible materials are a speciality product, developed for use by
medical professionals, and should be used in accordance with the instructions for use.
