This is a 100% Small Business Set-Aside solicitation for a Selection Laser Sintering (SLS) 3D printing system to be delivered to the RAPID Innovation Center at Hill Air Force Base, Utah. The government intends to award a single firm-fixed-price contract on a Lowest Price Technically Acceptable (LPTA) basis, considering price, technical compliance, past performance, and delivery. Offerors must indicate if they can achieve delivery within 4 weeks after receipt of order, or propose an alternative schedule. Pricing must remain valid for 90 days from proposal submission, unless an alternate realistic validity period is proposed. Performance and delivery will occur at Hill AFB, Utah, with the government evaluating only the lowest-priced offer first for technical acceptability.
