1. Nature of Service

Sinister Printworks LLC (“Sinister Printworks,” “we,” “us,” or “our”) operates as an on-demand 3D printing and manufacturing service. We manufacture physical objects from digital design files (including but not limited to STL, 3MF, OBJ, and STEP formats) submitted by customers (“Customer,” “you,” or “your”).

Sinister Printworks does not design, create, distribute, sell, license, or claim ownership of any digital design files submitted by customers. We function exclusively as a manufacturing service provider, producing physical objects from customer-supplied digital files. Our charges reflect materials consumed, machine time, labor, and overhead costs associated with the physical manufacturing process — not the intellectual property embodied in the design.

2. Customer Responsibility for Intellectual Property Rights

By submitting any digital design file to Sinister Printworks for manufacturing, the Customer represents, warrants, and certifies that:

• (a)The Customer is the original creator of the design, OR has obtained all necessary licenses, permissions, and authorizations from the rights holder(s) to have the design manufactured;
• (b)The design does not infringe upon any copyright, patent, trademark, trade secret, trade dress, or any other intellectual property right of any third party, whether registered or unregistered, under the laws of the United States or any foreign jurisdiction;
• (c)The Customer has obtained and can demonstrate proof of any required licensing agreements, including but not limited to commercial licenses, personal use licenses, derivative work permissions, and manufacturing rights;
• (d)The design does not constitute counterfeiting, unauthorized reproduction, or unlicensed duplication of any branded, trademarked, or copyrighted product, character, logo, or protected work;
• (e)The Customer has full legal authority and capacity to authorize the physical manufacture of the submitted design;
• (f)The design file was obtained through lawful means and the Customer possesses a legitimate copy of the file.

3. Indemnification

The Customer agrees to defend, indemnify, and hold harmless Sinister Printworks LLC, its owners, officers, employees, agents, and affiliates from and against any and all claims, demands, actions, suits, proceedings, damages, liabilities, losses, costs, and expenses (including but not limited to reasonable attorney’s fees and court costs) arising from or related to:

• (i)Any actual or alleged infringement of intellectual property rights resulting from the Customer’s submitted design files;
• (ii)Any breach of the representations and warranties set forth in Section 2;
• (iii)Any product liability claim arising from the Customer’s use, sale, distribution, or modification of the manufactured object;
• (iv)Any violation of applicable federal, state, or local law resulting from the design or use of the manufactured object.

This indemnification obligation shall survive the completion, cancellation, or termination of any order or business relationship between the parties.

5. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, INCLUDING THE KANSAS CONSUMER PROTECTION ACT (K.S.A. 50-623 ET SEQ.), SINISTER PRINTWORKS’ TOTAL LIABILITY TO THE CUSTOMER FOR ANY CLAIM ARISING FROM OR RELATED TO OUR SERVICES SHALL NOT EXCEED THE TOTAL AMOUNT PAID BY THE CUSTOMER FOR THE SPECIFIC ORDER GIVING RISE TO THE CLAIM.

IN NO EVENT SHALL SINISTER PRINTWORKS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF PROFITS, REVENUE, DATA, OR BUSINESS OPPORTUNITIES, REGARDLESS OF THE THEORY OF LIABILITY.

6. All Sales Final — No Warranty

ALL SALES ARE FINAL. SINISTER PRINTWORKS PROVIDES NO WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, ON MANUFACTURED ITEMS.

Sinister Printworks does not design, engineer, or validate customer-submitted designs for structural integrity, dimensional accuracy, or fitness for any particular purpose. All designs are created by and submitted by the Customer. The Customer bears full and sole responsibility for ensuring that designs are structurally sound, dimensionally accurate, and suitable for their intended purpose.

Sinister Printworks is not liable for part breakage, failure, deformation, or unsuitability after delivery. 3D printed parts are subject to the inherent material and process limitations of additive manufacturing, including but not limited to: layer adhesion characteristics, anisotropic strength properties, surface finish artifacts, dimensional tolerances, and thermal deformation. These are normal characteristics of 3D printing and do not constitute defects.

Package Insurance: Customers may elect to purchase optional package insurance during checkout to protect against physical damage occurring during transit. Without package insurance, risk of loss transfers to the customer once the package is handed to the shipping carrier. See our Terms of Service for full package insurance details.

7. Prohibited Items & Right of Refusal

Sinister Printworks reserves the absolute right to refuse any order at its sole discretion, without obligation to provide a reason. The following categories of items are strictly prohibited:

8. No Obligation to Review Intellectual Property Status

Sinister Printworks is under no obligation to investigate, verify, or confirm the intellectual property status of any design file submitted by a Customer. We do not conduct patent searches, copyright clearance reviews, trademark investigations, or any other form of IP due diligence on submitted files.

The mere acceptance of an order and manufacture of a submitted design shall not be construed as a representation by Sinister Printworks that the design is free of intellectual property encumbrances. The entire responsibility for ensuring proper licensing and rights clearance rests exclusively with the Customer.

9. Design File Handling

Customer design files are stored in encrypted cloud storage accessible only by Sinister Printworks manufacturing systems. Files are automatically purged thirty (30) days after order completion. Sinister Printworks does not share, sell, distribute, or publish customer design files. We claim no ownership interest in customer designs.

Notwithstanding the foregoing, Sinister Printworks may retain design files as reasonably necessary to comply with legal obligations, resolve disputes, or enforce agreements.
