What Our 3D Printing Clients Say

Accelerating innovation through additive manufacturing

"Alpine's SLS printing cut our prototype iteration cycle from 3 weeks to 3 days. We tested 8 design variations in the time it used to take for one. Their PA12 parts were strong enough for functional testing too."

David Park

Lead Product Designer, InnovateTech Labs

"We use Alpine for custom assembly jigs and fixtures. Their MJF technology produces parts with the dimensional accuracy we need, and the 48-hour turnaround means we can respond to production changes immediately."

Michelle Torres

Manufacturing Engineer, Precision Assembly Co.

"For our small-batch medical device components, 3D printing eliminated the $80,000 tooling investment. Alpine's SLA printing delivers the surface finish and detail we need for patient-facing parts."

Dr. Andrew Mills

Founder & CEO, BioDevice Innovations

Frequently Asked Questions

Common questions about our 3D printing services

Which 3D printing technology is best for my project?

The best technology depends on your requirements. FDM/FFF is cost-effective for large prototypes and functional testing. SLA/DLP provides the highest detail and smooth surfaces for visual prototypes and small intricate parts. SLS offers production-grade strength without support structures, ideal for functional end-use parts. MJF delivers fast production with excellent mechanical properties for small series manufacturing. Our team will review your design, application requirements, and budget to recommend the optimal technology.

How strong are 3D printed parts compared to injection molded parts?

Modern 3D printing materials can achieve 70-90% of injection molded part strength, with some technologies matching or exceeding it. SLS PA12 nylon parts have tensile strength around 48 MPa, comparable to injection molded nylon. MJF parts offer similar properties with better isotropy. FDM parts are generally weaker (especially in the Z-axis) but can be reinforced with carbon fiber. For production applications, we conduct mechanical testing to validate that printed parts meet your performance requirements.

What file formats do you accept?

We accept all standard 3D file formats including STL, OBJ, 3MF, STEP, IGES, and native CAD files (SolidWorks, Fusion 360, Inventor, CATIA). STL is most common for 3D printing, but we prefer STEP files when available as they preserve more design information. If you only have 2D drawings, our engineering team can create 3D models for you. We also accept scanned mesh files for reverse engineering projects.

Can you print in multiple colors or materials?

Yes, we offer several multi-color and multi-material options. For FDM, we can print with dual-material systems combining rigid and flexible materials or support and build materials. For full-color parts, we use color-jet technology or post-processing painting/dyeing. SLA parts can be painted or dyed after printing. For production parts requiring multiple materials, we can combine 3D printing with insert molding or assembly of separately printed components.

What post-processing options are available?

We offer comprehensive post-processing services including support removal, sanding, polishing, vapor smoothing (for FDM), dyeing, painting, powder coating, electroplating, and clear coating. For functional parts, we provide tapping, drilling, heat-set inserts, and assembly services. SLA parts can be sanded to a glass-smooth finish. SLS/MJF parts can be dyed black or other colors, or media blasted for uniform surface texture. We tailor post-processing to your aesthetic and functional requirements.

How accurate are 3D printed parts?

Accuracy varies by technology and part size. SLA/DLP offers the highest accuracy at ±0.1mm for small parts. SLS and MJF typically achieve ±0.3mm or ±0.3% (whichever is greater). FDM accuracy is ±0.5mm or ±0.5%. Factors affecting accuracy include part geometry, orientation, material shrinkage, and post-processing. For critical dimensions, we recommend secondary machining or designing with adjustment features. We provide dimensional reports for parts requiring verification.

Is 3D printing cost-effective for production quantities?

For quantities under 1,000 parts, 3D printing is often more cost-effective than injection molding due to zero tooling costs. The break-even point depends on part size and complexity - typically 500-5,000 parts. For ongoing production, we offer volume discounts and can optimize designs for printability to reduce costs. 3D printing also allows you to start production immediately and modify designs without tooling changes, providing flexibility that offsets higher per-part costs for many applications.

What is the maximum size part you can print?

Our build volumes vary by technology. FDM printers can produce parts up to 500 x 500 x 500mm, with large-format systems available for bigger parts. SLA build volumes are typically 300 x 300 x 400mm. SLS and MJF systems offer 380 x 284 x 380mm build volumes. For parts exceeding these dimensions, we can design them to be printed in sections and assembled. We also offer design consultation to optimize large parts for printing, including hollowing strategies to reduce material usage and print time.
