• The lead time stated is for the first article shipment. The remaining production time is confirmed after the first article approval.
• Typical first article shipments are 10 pieces.
• JSK Industrial Supply cannot guarantee a perfect color match per Pantone color.
• All quotes are based upon the assumption that designs have an adequate draft, radii, and coring for manufacturability.
• Cores, side actions, and tooling strategies are determined by JSK Industrial Supply unless explicitly discussed.
• Unless noted, tolerances are +/- 0.010″ between the manufactured part and 3D CAD. part-to-part repeatability is typically under 0.004″.
• Gating, ejection, knit lines, and parting lines are at the discretion of JSK Industrial Supply unless explicitly discussed.

• +/- 0.005” for the first inch is typical, plus +/- 0.002” for every inch thereafter. However, JSK Industrial Supply does not guarantee tolerances on the first attempt of a new design. Tolerance expectations can vary across different materials (e.g. stainless versus aluminum).
• Internal stresses during build, support strategy, and other geometry considerations may cause deviation intolerances and flatness.
  Items and geometries which require strict flatness are not a good fit for this process.
• The expected surface roughness is 150-400 µin RA, depending on the build orientation and material used for the build.

• Guaranteed tolerances may be possible with a manual quote review, and must be approved on a case-by-case basis.

SLS – Selective Laser Sintering

• +/- 0.005” for the first inch is typical, plus +/- 0.002” for every inch thereafter.
• Parts with thicker geometries, flat or broad parts, and parts with uneven wall thicknesses will be prone to significant deviations or warp due to variable thermal shrinkage and stress.
• Guaranteed tolerances may be possible with a manual quote review, and must be approved on a case-by-case basis.

HP MJF – HP Multi Jet Fusion

• +/- 0.012” for the first inch is typical, plus +/- 0.003” for every inch thereafter.
• Parts with thicker geometries, flat or broad parts, and parts with uneven wall thicknesses will be prone to significant deviations or warp due to variable thermal shrinkage and stress.
• Natural grey color may be inconsistent depending on feature size and build orientation. Dyed black is recommended for production parts.
• Guaranteed tolerances may be possible with a manual quote review, and must be approved on a case-by-case basis.

FDM – Fused Deposition Modeling

• XY Planes: +/- 0.004” for the first inch is typical, plus +/- 0.002” for every inch thereafter.
• Z Plane: +/- 0.010” for the first inch is typical, plus +/- 0.002” for every inch thereafter.
• JSK Industrial Supply chooses optimal build orientation taking into consideration overall surface quality and minimum build time unless otherwise specified.
• Minimum resolvable feature size, including positive text features, is at least 0.035” (0.045” or greater is safest).
• Nylon 12 parts with thicker geometries, flat or broad parts, and parts with uneven wall thicknesses will be prone to significant deviations or warp due to variable thermal shrinkage and stress.
• Guaranteed tolerances may be possible with a manual quote review, and must be approved on a case-by-case basis.

Carbon DLS – Digital Light Synthesis™

• +/- 0.005” for the first inch is typical, plus +/- 0.002” for every inch thereafter. However, JSK Industrial Supply does not guarantee tolerances on the first attempt of a new design. Tolerance expectations can vary across different materials (e.g. elastomeric versus rigid materials).
• Stresses during build, support strategy, and other geometry considerations may cause deviation intolerances and flatness.
• Parts with thicker geometries, flat or broad parts, and parts with uneven wall thicknesses may be prone to significant deviations or warp.
  Improved tolerances may be possible with a manual quote review, after successful completion of a prototype build, and must be approved on a case-by-case basis.

PolyJet

• +/- 0.004” for the first inch is typical, plus +/- 0.002” for every inch thereafter.
• The minimum feature size of 0.050” can be built with consistency.
• Rubber-like materials represent an approximation of shore A values and may vary between geometries.

• Forming and bending: +/- 0.020″
• Bend to hole or feature: +/- 0.010″
• Linear dimensions excluding locations to bends: +/- 0.005″
• Diameters with inserts: +0.003/-0
• Angularity: +/- 2 degrees
• Surface roughness (blank material): Ra 125 min max
• Surface roughness (timesaver): Ra 100 min max
• Sharp edges will be broken and deburred by default. Critical edges that must be left sharp should be noted and specified on a print.
• Certain sheet metal designs require custom tooling and will be flagged for a manual quote: hems, curled flanges and rolled sheets, stamped parts, and welded assemblies. If your part includes these features, please allow our manual quote team to review and provide you with an accurate cost and lead time.
• Flat parts: Sheet metal parts that utilize stock material gauge thicknesses and require no bending or milled features. All flat sheet metal parts can meet a +/-0.005” (+/- 0.127mm).

• Simple Bend / One Surface: When designing parts with some type of bend with a standard bend radius, sheet metal tolerances are required to open. For simple bent parts, Xometry can offer a +/- 0.010” (+/- 0.254mm) tolerance for dimensions across a single bend. The bend radius itself is constrained to a +/- 1.0°

• Multiple Surface Bends: For dimensions measured over multiple bends, JSK Industrial Supply can offer a +/- 0.030 (0.762mm).

This term refers to grinding after the firing process. Once this material is fired, the only thing harder is diamond. The only way to change the shape or size of a fired part is to grind, ream, or hone it with some type of impregnated diamond tools, such as wheels, reamers, or hones. Ceramic parts can be reamed or ground after firing to achieve a closer tolerance than what can normally be achieved prior to firing.
