3D Printing

Is 3D printing suitable for my needs?
To determine if 3D printing is a good solution for your business, you need to answer a few questions. What is my requirement (prototype or series production)? Does it address an existing issue? Is the choice of material suitable for your application? What is my production volume?
What are the steps in the 3D printing process?
3D printing consists of 4 main steps:
Modeling: The first step involves designing and modeling the 3D model to be printed using CAD (Computer-Aided Design) software.
Slicing: The modeling is then converted into a series of printable layers using slicing software. Printing parameters tailored to the machine and material are configured. This generates a G-code file that will be read and interpreted by the printer.
Printing: Before starting the printing process, preparations are needed, such as machine calibration, loading of the material, and uploading the G-code.
Post-processing: Once the printing is complete, some printing processes require cleaning of the part and the machine. Post-processing may include finishing tasks such as support removal, sanding, painting, etc.
What is MEX FDM?
The term FDM/FFF or MEX means “Material Extrusion”. The process involves extruding material layer by layer based on a 3D file. FDM/FFF are part of the MEX category by fused filament deposition. It is one of the most widespread additive manufacturing technologies, highly appreciated for the performance of its materials.
Is 3D design training necessary?
3D design training is necessary for 3D printing. If you wish to internalize production, 3D files will be provided by your clients if you are service providers.
Do I need a 3D design software?
A CAD software is necessary for the realization and design of parts to be 3D printed. To print a part, you need to provide a 3D file in .STL format. All CAD software allows exporting files in this format. There are different software options for different uses; learn more here: https://www.redbubble.com/fr/shop/ap/44102366?asc=u

3D Printers

Where are Lynxter 3D printers manufactured?
The design, technological development and the manufacturing of our Lynxter printers are done in France at our workshop in Bayonne. Lynxter also develops and formulates its own materials, such as SIL-001 or SUP-001.
Is the technology Plug & Play?
After training, users of Lynxter printers can operate them independently. We recommend printing with profiled materials and adhering to the printing rules and profiles developed by our teams (e.g., Design Guide for silicone).
How much power does a Lynxter 3D printer consume on average?
The S600D and S300X in LIQ configuration consume 500 W (equivalent to a computer’s consumption). The S600D in FIL configuration consumes 1000 W (equivalent to a dishwasher’s consumption) and can go up to 2500 W when printing PEKK-A (equivalent to an oven’s consumption).
Are Lynxter 3D printers safe?
Lynxter printers are equipped with an activated carbon filter and an HEPA 14 filter, ensuring safety against particle and VOC emissions. The enclosed print chamber helps protect users from machine movement.
I don’t live in France; where can I see one of your 3D printers?
Our 3D printers are distributed by various partners worldwide, which you can find here. If your country is not represented, please contact our teams directly.
How to choose the right Lynxter 3D printer?
The S600D is a modular and open industrial 3D printer that offers exceptional versatility. With its ability to easily switch toolheads, closed and heated printing chamber, and large printing volume, it can handle a wide range of materials, including liquids(Silicone and PU), technical filaments (PEKK, PA6-CF), and pastes. This printer is well-suited for research and education, production of industrial and technical parts in small to medium series, industrial maintenance, and functional prototyping. It is ideal for those seeking an adaptable and versatile machine.
The S300X is a 3D printer specialized in medical end industrial elastomers (Silicone and PU). Equipped with IDEX technology, it can print materials like silicone and PU with support material, allowing the creation of complex shapes. This elastomeric 3D printer is unique in the market and ensures industrial-grade prototypes and functional parts. It perfectly meets the needs of industries looking for flexibility and performance.
What sets Lynxter MEX silicone 3D printing apart from VPP (SLA/DLP/LED) silicone 3D printing?
Speed and efficiency: MEX processes are exceptionally efficient with minimal lead times, enabling swift production and customized designs on demand. Resolution is widely adjustable, parts can be small of big. VPP processes often require post-treatments, increasing complexity and time.
Uncompromised silicone quality: MEX leverages existing industrial-grade and medical grade silicone (skin-contact) materials, eliminating the need for UV curing that can result in weaker chemical and thermal resistance as well as vulnerability to UV exposure. These outcomes lead to silicone products that meet the highest quality standards : specifications of final parts are comparable with injection molded parts (vs. VPP which is a fraction of the propreties) They are well-suited for long-term and high-stress applications in extreme environments
Use & safety: MEX RTV2 silicone printing direct process involves non-toxic emission and requires no post-processing. The support material is water-soluble, posing no risk to users and waste treatment. In contrast, uncured VPP resins can be toxic, raising Health, Safety, and Environment (HSE) concerns. Post-treatment involves the use of IPA solvent, leading to important waste management and hazardous situations for the user.
Environmental footprint: MEX processes have a lower environmental impact due to fewer machines involved, reduced energy consumption, and access to industrial materials in larger quantities. While VPP can be competitive, it may have higher waste.
Multi-Material: Lynxter’s open technology enables the printing of any silicone material on both the S300X and S600D, and offers an affordable and ready-to-use industrial and medical grade silicones (SIL-001, COPSIL3D) for both machines. Playing with different toolheads and accessories allows printing different material in a single part. Also, printing on existing parts of any size is possible to add local features. VPP processes are primarily designed for single-material printing and can be restricted to proprietary materials. VPP processes are primarily designed for single-material printing and cannot be used on existing parts.
VPP vs. MEX: VPP and MEX processes complement each other, excelling in different areas. VPP processes are suitable for small batches with low durability requirements and a focus on surface finish, whereas MEX processes shine in applications with high HSE constraints, quick ROI, and accessibility to a broader market. The choice between VPP and MEX processes depends on the specific application requirements. If mechanical properties like flexibility and durability are critical, and if traditional silicone characteristics are needed, then MEX is likely the better choice.
Cost of ownership: MEX silicone 3D printing typically offers advantages with lower materials costs (silicone and support), lower maintenance costs, reduced operating costs, less material waste, and greater material flexibility but higher acquisition cost when it comes to industrial 3D printers, MEX is also faster with higher throughput and typically requires less post-processing compared to VPP 3D printing. VPP 3D printing can involve smaller acquisition costs, but specialized and potentially more expensive resins, increased maintenance costs due to resin-handling systems, higher operating costs, more material waste due to materials from support structures and left over resins, and limited material availability
Do Lynxter 3D printers require special ventilation or air filtration systems?
Lynxter 3D printers are equipped with closed printing chamber, activated carbon filters and HEPA 14 filters to ensure safety against particle and VOC emissions.
What is the recommended procedure for cleaning and maintaining Lynxter 3D printers?
Cleaning and maintenance procedures for Lynxter 3D printers can vary depending on the specific printer model and usage. It’s essential to follow the guidelines provided in the user manual and any maintenance documentation provided by Lynxter. Regular cleaning, inspection, and maintenance of key components, such as nozzles and filters, are typically recommended to ensure optimal printer performance.
What is the maximum printing volume?
The printing volume on the S600D varies depending on the used toolhead:

– FIL21 = Ø 360 mm x 600 mm
– FIL33 = Ø 345 mm x 600 mm
– LIQ11/21 = Ø 390 mm x 600 mm
– PAS11 = Ø 360 mm x 600 mm
For the silicone 3D printer S300X, the maximum printing volume is 300 x 250 x 200mm.
