FDM is a fast, cheap and fairly efficient way of making 3D printed parts. In FDM, plastic filament is squeezed through hotend, melting it and then deposited in pre-defined path layers by layer to create a form. We have a large facility for FDM 3D printing service in Pune, ready for prototyping or batch production. With 6+ material support and multiple post-processing options, receive your functional 3D printed parts within days.

FDM Post Processing Options

Removal of the support structure is the most basic form of post-processing. Support removal is an easy process unless there are supports in hard-to-reach places. There are two types of supports, soluble or insoluble. Soluble supports are easy to remove and provide a better finish on the supported member.

We provide both soluble and insoluble support options to our customers and support removal as a standard post-processing service.

Sanding is the most common method of post-processing. FDM 3D prints can have a slightly rough surface, and sanding is the easiest way to smooth it. For large prints, we provide sanding as an additional post-processing service. The part tolerance can vary up to 500 microns, thus it is suggested to avoid sanding of tolerance sensitive 3D printed parts.

Priming and painting post-processing methods are for enhancing the look, adding colour, as well as the finish of a part. Priming and painting are not recommended for tolerance sensitive 3D printed parts. We have a team of skilled creators for professional priming and painting services. Just upload the 3D model and list the colour of your choice to receive an instant quotation.

Cold welding is a standard 3D printing service for large ABS 3D prints or 3D printing complex parts with a minimal support structure.

Smoothing is a popular post-processing technique for ABS prints. Acetone is used to melt the upper layer of ABS print and therefore smooth away the layer lines visible on a part’s surface. This makes 3D printed parts look smooth and shiny but dimensional accuracy is compromised. We provide vapour smoothing as an additional post-processing service.

Epoxy coating of 3D printed model is carried for improving strength and adding a durable protective layer. But this post-processing method seals all porous parts of the print. This is not a finishing technique so the layer line still may be visible. We provide epoxy coating as an optional post-processing service for FDM 3D printing in Pune facility.



FDM Design Guidelines

  • Shrinkage

    This shrinkage is a direct result of the transition from a semi-solid to a solid-state during the FDM process. Various factors are contributing to the shrinkage of 3D printed parts such as type of material environmental temperature. On average the shrinkage rate of PLA is somewhere between 2.0%-2.5%, ABS between 8%-9% and that of nylon is less than 1.7%. We take care of shrinkage through slicer settings and machine calibration, so all the 3D printed parts by DigiPro 3D are within the tolerance limit.

  • Minimum Wall Thickness

    Wall thickness is limited by the nozzle diameter and features thinner than 90% of the nozzle size usually does not print successfully. Features with only one layer of the wall are weak and inaccurate. For supporting structures, walls need to be at least 1.2 - 1.5 mm thick for best results by allowing the filament to fill between layers.

  • Hole Orientation

    Holes on an FDM part are generally undersized. Orientation of holes is very important and they tend to be more accurate when printed parallel to the build plate. DigiPro 3D recommends minimum diameter of holes for FDM be designed greater than 1mm to retain a circular shape. For maintaining tight tolerances, holes will be drilled or reamed to ensure the diameter is as designed.

  • Threads

    For fine threads in FDM, it is more appropriate to incorporate a heat-set insert into your design, which is added after your part has been 3D printed. It is possible to 3D print functional threads if they are large and coarse. When using modelled thread, Creating an ACME thread design with rounded roots and crests has been found to work well. Also for better printability in FDM, the pitch of the thread should be more than 1.5mm.

  • Text and small details

    Texts and small details are very hard to 3D print as many small features do not register during the slicing process. It is recommended to use a font with consistent text width. Minimum suggested text width must be 1.2mm- 1.5mm and protrusion 1mm to be legible and avoid unexpected errors.

  • > 450Supports


    When the printed layer of material is only partially supported by the previous layer, it's considered an overhang. The maximum inclination for an overhang is 450, i.e overhang is successfully printed without supports up to 450. For inclination greater than that a support structure is required to avoid print failure.

  • Fillets and Ribs

    If there are sharp corners or edges in the part stress concentration at these regions is high so are the chance of failure under load. Fillets and ribs can be used to decrease stress concentration and increase strength thus chance of failure is reduced. If fillet or rib is applied to a small overhang the support structure requirement can be eliminated. For FDM 3D printed part, it is advised to keep a fillet radius greater than 1 mm.

  • Orientation

    FDM 3D printed parts are anisotropic due to the nature of the process. Orientation has an enormous impact on anisotropic behaviour and appearance. The extruded part has more tensile strength along the XY plane and lower strength in the z-direction. Critical features such as circle, steep curvature print better when printed parallel to the XY plane. Designing a part so that weak and concentric features are placed in the parallel direction to the XY plane will help determine the best orientation for a part. Overhanging features along z-direction requires support during 3D printing which increases build time and material usage. A designer should ensure to minimize such overhangs in a model.

  • FDM Design Guidelines assemblies #1


    DigiPro 3D can produce fully assembled 3D printed parts provided proper clearance is given between mating assembly parts. The X/Y clearance should be greater than the default extrusion width and Z clearance greater than slice thickness.

  • Post-processing

    Parts manufactured by the FDM 3D printing method can be subjected to various post-processing including machining operations such as drilling and tapping, turning, and milling. DigiPro 3D provides services for surface finishing like smoothing, burnishing, sealing and plating.

General FDM Tolerances

FDM tolerances for 0.1mm slice thickness are given below, these are subjected to change with change in print parameters.

Applications of FDM

Benefits of FDM

With calculated compensation for shrinkage and post-processing method FDM printed parts are accurate and within process tolerance. Complex geometries and cavities that would otherwise be problematic become practical with FDM technology.

FDM technology supports production-grade thermoplastics that are mechanically and environmentally stable. For these thermoplastics range of post-processing methods are available. At DigiPro 3D, we suggest the correct combination to deliver a market-ready product.

The FDM process uses engineering-grade thermoplastic filament that is easily available and affordable. FDM machines have a modest size means parts don’t have to be manufactured in a large facility, helping to lower the expense of producing small components. DigiPro 3D provides cost-effective services for FDM in Pune facility.
