Quick answers about our offerings, processes, and how we can support your projects.Please read carefully.
Our lead times are considerably shorter compared to competitors. Depending on the project's scope, this may be a few hours, to days, to 1 to 2 weeks. For comparison, any custom (non-standard dimension) product or parts from our competitors can take up to between 6 and 16 weeks! Often times we will dedicate entire machines just to meet the needs of our clients.
Simply reach out through our contact form or call our office. We'll schedule an initial consultation to discuss your project requirements, goals, materials, and timeline. From there, we’ll get you onboarded and develop a detailed plan tailored to your needs. We do offer expedited services when needed.We do require a 50% deposit on projects for new customers. We may wave this in the event of expedited orders.
We serve an array of industries, including automotive, aerospace, energy, infrastructure, heavy machinery, medical, and OEM. We consider ourselves "industry agnostic". America's industrial and manufacturing sectors are our focus. Rarely do we work directly with individual consumers.
Depending on the method of production and material, the surface finish can vary quite a bit. FDM printed parts will have layer lines between 0.10mm and 0.30mm thick (± 0.05mm) Resin based prints, or parts derived from plastic injection molds made of resin, will contain fully-dense and isotropic features. Tolerances for FDM are as low at 0.1mm, while resin can achieve tolerances as low as 0.05mm. Pure resin prints and injections molds will have the best surface finishes and ability to adhere to strict tolerances — but will require the most post processing.
We offer just about every filament you can name, including reinforced variants. Filaments denoted CF contain carbon fiber, those denoted GF contain glass fiber. We offer the following engineering filaments: ABSASA-CF/GFNylon-CF/GF (AKA Polyamide or PA),PETG-CF/GFPC-CF/GF (Polycarbonate)PET-CFPPA-CFPETG-TungstenPEEK-CF/GFPEI (Ultem)PEKK-CFPP (Polypropylene)PPS-CF ((Polyphenylene Sulfide)TPUFor resins, we offer engineering resins that can contain glass fibers to support high heat and high stress applications. We also carry non-engineering resins for aesthetic or cosmetic prints. The engineering resins are what we use for quick turn around on parts that need injection molding.
It depends.If you need parts where surface finishes are a lower priority (i.e. layer lines, small imperfections, support scarring, seams, stringing), FDM is the way to go. We do our best to avoid these "imperfections" from occurring at all. FDM is scalable, cheap, and still allows for complete functionality. The types of plastic available in this method are numerous (see above). We recommend this method for components that will be out of sight and out of mind (though some parts can be printed with high resolution and nice surfaces finishes). This is the preferred method for functional and rapid prototyping. Depending on the parts function, print orientation will matter.If you need a handful of parts where aesthetics do matter, then go with SLA (resin printing). Resin printed parts have uniformed surface finishes with high accuracy. These parts are also solid and have isotropic strength profiles. Nicely textured surfaces are possible with this method. Use this method for parts requiring finer details. Certain resins do have engineering properties that are comparable to injection molded parts (i.e. they are described as "ABS-like"). If the part is small, the quantity can be scaled up very quickly via this method.If large quantities are needed with high repeatability and accuracy, then resin-based injection molding will be your answer. We can manufacture resin-based injection mold cavities with high heat resistance and low deflection, quickly. In some cases, these molds can last a few hundred (even thousand) shots before breaking or falling out of tolerance (contingent on the injected plastic composition and pressure used). We do require an MOQ (minimum order quantity) for this method. Injected plastics with high glass or carbon fiber content, coupled with higher injection temperatures, will significantly degrade the molds after only a few injections.
Customer part density will vary based on the customer's needs. For FDM produced parts requiring higher structural strength, we recommend 50%+ for infill. For general function parts, 20% to 50% is sufficient. For cosmetic and aesthetic parts, 10% to 20% infill works. Though some FDM filaments can come in different colors, we generally discourage color on parts that require structural strength as there is some evidence to suggest that color additives may affect their strength profile. When possible, we recommend "natural" filament color (i.e. PEEK is light brown naturally, most carbon fiber based prints are matte black).The FDM parts we designed for our shop ship with between 20% and 30% infill (item and design dependent). If a different color is needed, it will be subjected to additional charges. If higher infill is required, it will come at an additional charge. Parts found in our "Shop" are either black, white, grey/carbon fiber matte black, or "natural" color. Parts printed in resin or injection molded will be solid, unless designed otherwise. Color choice for resin prints are limited as well.
Yes!We offer free samples for some of the FDM parts found in our shop.
Our shop features parts that we designed with certain applications in mind. For example, you may find industrial shaped knobs or handles that can be customized to fit your application — custom dimensions are denoted by a letter next to the drawing datum (i.e. 2.0 D). The parts are primarily aimed at industrial sectors, such as general manufacturing, lighting, security, etc.
We plan on offering SLS (Selective Laser Sintering) and eventually DMLS (Direct Metal Laser Sintering) in the future, based on our customer's demands. Mithril will also look at providing non-additive services such as laser cutting, waterjet, and multi-axis CNC milling or lathe. We are a factory, not a farm!
We do not make toys... So don't send us any of those stupid Etsy dragons to print.Our reasoning for this can be found in one of our blog posts.We will make props and figurines, so long as they are not multicolor.
