WHY FDM Prototpes?
Benefits of Using FDM
- Durable Materials – Unlike SLA or SLS which use resins, FDM uses real production-grade thermoplastics. In fact, they are the same high-performance raw materials used in most injection molding technologies.
- Build Accuracy – FDM technology builds the most accurate parts of any additive fabrication system.
- Part Repeatability – Unlike Stereolithography (SLA) and Selective Laser Sintering (SLS) that use resins to build your models, FDM uses real thermoplastics. SLA & SLS resins deteriorate over time. Their lasers also depreciate over time making it difficult to ensure repeatability. With FDM, we can produce the same part consistently.

Electroplating Electroplating deposits a thin layer of metal on the surface of a part built on a Fortus 3D Production System. This improves the part’s mechanical properties and gives the appearance of production metal or plated parts and provides a hard, wear-resistant surface with reflective properties.
Extrusion Blow Molding Polycarbonate FDM molds are used in the blow molding process, reducing lead time and expense. In five days or less, companies can design a mold, build the tool and blow mold near production-quality prototypes.
Fiberglass forms using FDM moldsNC machining is a costly and time consuming process to produce a lay-up. Handcrafting a lay-up mold is a laborious process requiring skilled workers. Much of this labor goes into the mold’s lay-up, but a lot of time will go into the design iterations. Using FDM to produce the molds can reduce labor costs and time.
Investment Casting Investment casting, also called lost wax casting, is widely used for producing ferrous and nonferrous metal parts. Unlike other casting processes, investment casting produces net shape parts with excellent surface finish and dimensional accuracy. Using FDM eliminates the need for tooling in the casting process, saving weeks of production time.
Manufacturing Tools Manufacturing engineers rely on tools such as jigs fixtures, templates, and gauges. Fortus 3D Production Systems produce manufacturing tools in hours. Producing parts in thermoplastic reduces part weight, consolidates into a single build, allows you to design for function, and makes iterations quickly.
Modular Fixtures A modular fixturing system is commonly used to stage parts for CMM inspections, hold work pieces during machining and position parts when bonding or assembling. Magics RapidFit module by Materialise automates the digital design process, and with just a few mouse clicks, the files are ready for production on a Fortus system.
Paper Pulp A Fortus 3D Production System is a great fit for mold making because of its thermoplastic durability. The flexibility of Fortus thermoplastic materials makes the continual vacuum/reverse-flow cycle possible without plastic cracking. After many cycles, FDM molds have shown little to no wear.
Polystyrene Molds PPSF thermoplastic used by Fortus 3D Production Systems withstands high temperatures used to manufacture EPS (expandable polystyrene) parts for helmet liners. Using the FDM Process, Gentex saved $3,360-$6,360 per mold assembly and shaved 4 weeks off the manufacturing process.
RTV Molds Parts built on a Fortus 3D Production System using FDM technology provide the fast, accurate and affordable patterns that drive RTV molding. By replacing machined patterns, the entire process can be completed in 2-3 days. And unlike machining, complex and intricate shapes have no effect on the time or cost for the FDM pattern.
RTV Molding Soluble Core Complex geometries normally requiring core removal such as curved hoses, water tanks, bottles, and arterial structures are good examples where it may be helpful to use this alternative method. Instead of building the core in thermoplastic material (traditional FDM build process) the mold is built in the Water Soluble support material making it easy to dissolve away the material after casting.
Sand Casting FDM thermoplastic matchplate mounted on an automatic molding machine can withstand the ramming forces used to pack sand casting tools. Using a Fortus 3D Production System to produce the match plate reduces the lead time from weeks to days.
Thermoforming Fortus 3D Production Systems can quickly produce thermoforming molds in less time than conventional means. The thermoforming process becomes simpler, more efficient and increasingly cost-effective.
Wind Tunnel When compared to machining and model making, FDM is a faster, less expensive and more efficient method for making detailed and accurate models for wind tunnel testing. The mechanical properties of ABS-M30, polycarbonate (PC), PC-ABS and polyphenolsulfone (PPSF) can withstand airflow forces and stresses.
Spin Casting By replacing machined metal patterns with models produced on a Fortus 3D Production System, the entire spin casting process, including pattern making, can be completed in as little as one day. FDM thermoplastic materials can endure temperatures of 300-350 degrees F and pressures of 800 to 3,500 psi necessary during the vulcanization process. Injection Blow Molding

Carbon Fiber Lay-up Molds using Fortus Thermoplastic Fortus thermoplastic materials have been validated to withstand high temperatures and vacuum pressure during the fiberglass lay-up process and FDM has become a new method to produce fiber molds. Producing a mold on a Fortus production system decreases lead times, is less expensive and is more accurate.
