StrengthMax™ is a high-strength epoxy infiltrant specifically formulated for 3D Systems. StrengthMax™ has low viscosity and is designed to fortify parts built on 3D Systems' ProJet CJP x60 series of printers. Parts infiltrated with StrengthMax™ are easily sanded and can be surface machined. StrengthMax™ will give you a very hard, very rigid, and very strong part.
StrengthMax™ is a two-part system. It is available in small pre-weighed kits, or in large sizes with pumps for easy dispensing and measuring.

Keep any remaining mixed materials and soiled paper towels under a ventilated hood until they have cured and cooled to room temperature. They are then safe to dispose of in regular trash.
Parts infiltrated with StrengthMax can be machined for functionality and part testing. Dry machining is recommended for milling, drilling, tapping, and boring. For best results when drilling and tapping, add a guide hole to the 3D model prior to printing.
The torque that can be safely applied to tapped holes, or to holes with Heli-Coil® screw thread inserts, is shown in the table below.
Thread Size | Tapped Hole | Inserted Heli-Coil |
---|---|---|
2-56 | - | 45 in-oz |
4-40 | - | 70 in-oz |
6-32 | - | 112 in-oz |
10-24 | 80 in-oz | 20 in-lbs |
1/4-20 | 20 in-lbs | 40 in-lbs |
5/16-18 | 40 in-lbs | 55 in-lbs |
When a smooth painted appearance is desired, parts should be primed.
The primer and clear coat are available at most auto body supply stores. The best results are obtained when these products are allowed to dry overnight. |

To maintain high strength in the seams, use a structural adhesive to bond the 2 parts together.
When using adhesives, follow the mixing instructions carefully and apply to the surfaces to be bonded. Clamping or taping the parts together may be required with some of these adhesives while letting the assembly cure for the recommended time.
StrengthMax™ should always be stored in a cool, dry place as indicated on the label. The shelf life of StrengthMax™ is two (2) years from the date of manufacture.
