Terms of Service

8.1 Intended Use

MarsWork Products are designed for additive manufacturing (3D printing) of thermoplastic filaments, depending on the specific Product. We ask that Products be used in accordance with the included documentation, safety guidelines, and applicable laws.

8.2 Safety Warnings

Important Safety Information:

• Filament off-gassing: Some filaments (ABS, ASA, PC, nylon) emit volatile organic compounds (VOCs) and ultrafine particles (UFPs) when heated. We recommend ensuring adequate ventilation or using an enclosure with HEPA/activated carbon filtration.
• Fire safety: We recommend not leaving a 3D printer operating unattended for extended periods. Please use a smoke detector in the printing area and place the printer on a stable, non-flammable surface away from combustible materials.

8.3 Prohibited Uses

Please refrain from using MarsWork Products to:

• Manufacture firearms, weapons, or any item regulated, restricted, or prohibited under applicable law;
• Manufacture items that infringe the intellectual property rights of others;
• Manufacture items intended for medical, surgical, or life-critical applications where failure could result in bodily harm, unless the specific Product is certified for such use;
• Manufacture currency, identification documents, or security features;
• Modify the Product's safety systems, thermal runaway protection, or firmware in a manner that bypasses built-in safety mechanisms;
• Operate the Product in environments not suitable for electronic equipment (e.g., wet, explosive, or extreme temperature environments).

8.4 Modifications and Customization

The 3D printing community has a strong tradition of customization, and MarsWork supports responsible modification of our Products. However, please note that any modification to hardware, firmware, or software not officially approved by MarsWork will void the warranty and may introduce safety risks. You assume responsibility for any consequences arising from unauthorized modifications.

9.1 Third-Party Consumables

MarsWork 3D printers are designed to work with a wide range of third-party filaments and resins that meet industry-standard specifications (e.g., 1.75 mm diameter filament). While we do not prohibit the use of third-party consumables, we are unable to guarantee print quality, dimensional accuracy, or machine compatibility when using non-MarsWork materials.

Please be aware that using third-party consumables which do not meet published specifications (e.g., significantly oversized filament causing extruder jams, or resin with incompatible wavelength requirements) may damage your printer and will void the warranty for the affected components.

9.2 Material Properties

Published material properties (tensile strength, heat deflection temperature, impact resistance, etc.) are based on injection-molded test specimens manufactured under controlled laboratory conditions per ASTM/ISO standards. 3D-printed parts typically exhibit 60–85% of these values due to layer adhesion characteristics and anisotropic structure. Always conduct your own testing for critical applications.

9.3 Storage and Handling

Most 3D printing filaments are hygroscopic and will absorb moisture from the air, leading to print defects such as stringing, popping, brittleness, and poor layer adhesion. We recommend storing filament in a cool, dry place with desiccant, or in a sealed container with humidity below 15% RH. Resin should be stored in opaque containers away from UV light sources. MarsWork is not responsible for print failures or material degradation caused by improper storage.

9.4 Print Results

While we design our Products to deliver excellent print quality, we cannot guarantee specific print outcomes. Print quality depends on numerous variables including but not limited to: slicer settings, model geometry, material quality, ambient temperature, humidity, printer calibration, nozzle wear, bed adhesion method, and post-processing techniques.

10.1 What Is Covered

This warranty covers defects in materials and workmanship under normal use during the warranty period. If a defect arises during the warranty period, MarsWork will, at its discretion: (a) repair the defective component; (b) replace the defective component with a new or refurbished equivalent; or (c) issue a partial or full refund.

10.2 What Is Not Covered

• Damage caused by misuse, abuse, accident, or failure to follow operating instructions;
• Damage caused by unauthorized modifications, third-party firmware, or hardware alterations;
  
• Damage caused by using non-compatible or out-of-specification consumables;
• Damage caused by improper storage, transportation, or environmental exposure (moisture, dust, extreme temperatures);
• Cosmetic damage that does not affect functionality;
• Damage caused by force majeure events (fire, flood, lightning, power surges);
• Issues arising from user-assembled kit errors (for DIY/kit Products);
• Software issues caused by incompatible third-party slicer configurations or unsupported operating systems.

10.3 Warranty Claims

To file a warranty claim, please contact marswork3d@outlook.com with your order number, a description of the defect, and photos or videos demonstrating the issue. MarsWork may request additional diagnostic information or a remote troubleshooting session before approving a claim. Approved warranty repairs or replacements will be shipped at MarsWork's expense; we kindly ask that you cover return shipping of the defective item if requested.

11.1 Return Eligibility

Unused Products in their original packaging may be returned within 30 days of delivery for a full refund, subject to the conditions below. Products should be in resalable condition with all accessories, documentation, and packaging intact.

11.2 Non-Returnable Items

• Opened filament spools;
  
• Custom or personalized Products;
• Software licenses or digital downloads;
• Clearance or final-sale items.

11.3 Return Process

Please contact marswork3d@outlook.com to obtain a Return Merchandise Authorization (RMA) number before shipping any item back. Returns sent without an RMA number may be declined. Return shipping costs are the customer's responsibility unless the return is due to a MarsWork error or a confirmed product defect.

11.4 Refund Processing

Approved refunds will be processed within 5–10 business days of receiving and inspecting the returned Product. Refunds will be issued to the original payment method. Shipping charges are non-refundable except where required by law.

12.1 General Limitation

To the fullest extent permitted by applicable law, MarsWork, its directors, officers, employees, affiliates, agents, and suppliers shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to lost profits, lost revenue, lost data, business interruption, property damage, personal injury, or other damages arising out of or related to the use of our Products or Services, whether based on warranty, contract, tort (including negligence), statute, or any other legal theory, even if MarsWork has been advised of the possibility of such damages.

12.2 Monetary Cap

MarsWork's total aggregate liability for any claim arising out of or relating to these Terms or our Products or Services is limited to the amount you paid to MarsWork for the specific Product or Service that is the subject of the claim, or USD $100, whichever is greater.

12.3 Essential Basis

The limitations and exclusions in this section reflect a reasonable allocation of risk between you and MarsWork and form an essential basis of the agreement between us. Without these limitations, MarsWork would not be able to offer its Products and Services at the current prices.

Consumer Protection Notice:Some jurisdictions do not allow the exclusion or limitation of certain damages or liability. If you are a consumer in such a jurisdiction (e.g., EU, UK, Australia), the above limitations apply only to the extent permitted by applicable mandatory consumer protection laws.
