Draft an enforceable limited warranty clause that excludes the warranty of merchantability.  You just need to draft this specific clause, not the rest of the contract.  Use examples in the textbook for guidance.  The Seller is willing to warrant title and that the Printer does not infringe on any patents or copyrights.  The Seller will repair or replace without charge any part which proves to be defective in material or workmanship within the first 1,000 hours of operation of the Printer or six months from the date of delivery, whichever comes first.  When drafting the clause use the terms Seller and Buyer.  The product being sold is an INTAMSYS FUNMAT PRO LARGE FORMAT INDUSTRIAL 3D PRINTER. which you may refer to in the clause as "the 3D Printer".
