Below is a collection of common questions about 3D printing and Advanced Engineering’s services and capabilities. If you can’t find what you’re looking for, please contact us to speak with one of our friendly engineers.


Can (or will) you 3D print firearms?

We do not possess a Federal Firearms License (FFL) so we cannot manufacture any firearm component which bears a serial number or requires an FFL to produce.

We can, however, produce other prototype components and/or accessories such as grips, sights and sight mounts, stocks, etc. We reserve the right to refuse any component build if we feel that it may violate Federal and/or State laws.

To learn more about 3D printed firearm components, please visit the Bureau of Alcohol, Tobacco, Firearms and Explosives website at https://www.atf.gov/qa-category/3-d-printing-technology-firearms.

How do I specify tolerances and other features?

Since STL files do not carry tolerance or other information it is helpful to include a drawing with your quote request showing critical dimensions, threads, surface finish requirements, etc.

How much is shipping?
We can ship your items via UPS®, FedEx® or the United States Postal Service. All items are shipped FOB our facility in Minneapolis, Minnesota 55432.
What is the maximum size part you can print?
Our Stratasys® Objet500 Connex3™ 3D printer has a maximum build envelope of 490 × 390 × 200 mm (19.3 × 15.4 × 7.9 inches). These dimensions include support material so the maximum actual part size is approximately 487 x 387 x 197 mm (19.2 x 15.3 x 7.8 inches).
What is your normal delivery time?
Our standard delivery time is one (1) week after receipt of order and/or payment. Delivery times are always subject to confirmation based upon available capacity at the time you place your order. Expedited delivery times are available. Please contact us for details.


Can you print flexible materials?


TangoBlackPlus and TangoPlus are both 27 Shore “A” Durometer (approximately the firmness of a typical office rubber band) in their natural state. Black, white, clear or colored rigid materials may be combined with TangoBlackPlus or TangoPlus to yield Shore “A” Durometers of 40, 50, 60, 70, 85 and 95 (approximately the hardness of an inline skate wheel).

Agilus 30 Black and Agilus 30 Clear are both 30 Shore “A” Durometer (slightly firmer than a typical office rubber band) in their natural state. Black, white, clear or colored rigid materials may be combined with Agilus 30 Black or Agilus 30 Clear to yield Shore “A” Durometers of 40, 50, 60, 70, 85 and 95 (approximately the hardness of an inline skate wheel).

TangoBlack is 61 Shore “A” Durometer in its natural state. Black, white, clear or colored rigid materials may be combined with TangoBlack to yield Shore “A” Durometers of 80, 85 and 95 (approximately the hardness of an inline skate wheel).

TangoGray is 75 Shore “A” Durometer in its natural state. Black, white, clear or colored rigid materials may be combined with TangoGray to yield a Shore “A” Durometer of 80.

Can you print transparent plastic?
Yes. Both the Stratasys VeroClear (FullCure 810) and MED610 rigid materials are fully transparent. Please note that even when printing in glossy finish mode, surfaces that are in contact with support material (inside diameters, bottom surfaces, and surfaces below the “equator” of the part) will have a matte finish. Mechanical polishing is required to achieve full optical transparency over the entire part. Please contact us for details.
Do you offer 3D printed materials that can be sterilized?
Yes. The Stratasys MED610 bio-compatible material is suitable for autoclave sterilization.


Can I get an NDA (Non-Disclosure Agreement) executed before I send my file(s)?
Yes. If you have an existing agreement we would be happy to review and sign it. If not, we can send you a standard agreement that we have used for a number of years.
I have an existing part/model. If I send it to you can you 3D scan it and print it for me?
In most cases the answer is yes. Depending upon the size and the amount of detail we can have your part 3D scanned by one of our partners and then print it for you. Please contact us to discuss your project further.
I have an idea for a revolutionary new product. Can you help me design and/or manufacture it?
In most cases, the answer is yes. We have mechanical, electrical and industrial engineers either on staff or with one of our partner companies who collectively have years of design and manufacturing experience in a wide variety of industries. Please contact us to discuss your project further.
What files types do you accept?

In addition to industry standard *.STL (STereoLithography or Standard Tesselation Language) files, we can accept Stratasys Objet Studio Tray (*.OTF; *.OBJTF) files or Packed Job (*.OBJZF; *.OZF) files. These file types typically import directly into the printer with little or no pre-processing required.

We use SolidWorks® CAD software internally so we can also accept native SolidWorks part (*.PRT; *.SLDPRT) or assembly (*.ASM; *.SLDASM) files with only a minimal amount of pre-processing before exporting to the required *.STL format.

For anatomical modeling projects, we can accept DICOM (Digital Imaging and Communications in Medicine — ISO 12052) formatted file sets. In order to comply with HIPAA (Health Insurance Portability and Accountability Act of 1996) these must be “anonymized” to remove patient-specific data prior to submission for 3D printing. The file sets must also undergo a “segmentation” process to convert them to printable *.STL format files. Please contact Advanced Engineering for further details.

In addition, the following CAD format files can typically be imported:

ACIS™ part or assembly (*.SAT) files up to and including version R22

Autodesk Inventor® part (*.IPT) and assembly (*.IAM) files. The imported part files can contain features or geometry only and must be version 11 or above.

CADKEY® version 19 or later part or assembly (*.PRT) files and version 21 multi-body part (*.CKD) files.

CATIA™ Graphics (*.CGR) files up to V5R22.

DXF 3D (*.DXF) files generated by AutoCAD version R14 and above and containing ACIS information. The import process does not convert from 2D to 3D and does not import wireframe data.

DXF (*.DXF) or DWG (*.DWG) files from AutoCAD versions 2013 to 2015.

IFC2X3 (*.IFC) parts or assemblies.

IGES surface and BREP solid (*.IGS; *.IGES) files.

Mechanical Desktop (*.MDT) translator parts or assemblies of version 4.0 through MDT 2008.1.

Parasolid text or binary (*.X_T; *.X_B; *.XMT_TXT; or *.XMT_BIN) files.

Pro/ENGINEER® part (*.PRT; *.PRT.*; *.XPR) or Creo Parametric assembly (*.ASM;*.ASM.*; *.XAS) files up to Creo 2.0.

Rhino® (*.3DM) files.

Solid Edge®: Parasolid information from Solid Edge part (*.PAR; *.PSM) or assembly (*.ASM) files.

STEP Application Protocol AP203/214 part or assembly (*.STP; *.STEP) files.

Unigraphics®: Parasolid information from Unigraphics part or assembly (*.PRT) files version 10 and higher including NX 7.5 files.

VDAFS (*.VDA) files.

VRML (*.WRL) part or assembly files up to and including VRML version 2 (VRML 97).

Please note that in some cases there may be significant pre-processing required before a particular file is printable.


What are your payment terms?

We require prepayment unless credit terms are established before the start of your project. We accept cash, checks, and Visa®, MasterCard®, American Express® or Discover® cards (processed through Square®). Once credit terms are established our payment terms are Net Thirty (30) Days.

We charge Minnesota sales tax where applicable unless we have a resale/tax exemption certificate on file.

What is the least expensive material you offer?
At a cost approximately 24% lower than the average PolyJet material, Stratasys RGD720 rigid translucent material is the lowest cost PolyJet material we have available.
