I am a Shapeways Designer, How do your services compare?

Like Shapeways, we offer a marketplace and the printing and fulfillment services to support it. However, our capabilities are currently not as diverse as Shapeways'. At present, we offer SLA and FDM printing on our select SLA, MSLA, and FDM printers.

We plan to expand and grow our capacity and capabilities as we progress. Please contact us with your specific needs, and we will explore how we can grow to meet them.

Please contact us at info@3dptrain.com for other questions.

How much do I make from each sale?

We veiw our marketplace as a partnership between us and our vendors. When you upload a model to our site we set the wholesale price (your vendor cost), you then set the retail price. When your model sells, the difference is added to your account balance to be payed out to you.

My models dont fit into your current categories.

That is not a problem, we can add new categories as needed.

I sell models that are not trains, can I sell on your platform?

Short answer, yes.

We are able to print most 3d models on our resin printers. While our main focus is model trains that also includes sceanic items and other miniatures that would be of interest to modelers. We are currently allowing other products on our marketplace as many designers had a wide variety of products and interests. In time we will watch how these non-train categories grow and determine the best steps forward.

If you are unsure if your mode is a fit, please contact us at info@3dptrain.com.

How are vendors paid?

Effective September 1st, payments will be automaticly paid 15 days after the customer has recieved their items. If you have any questions let us know.

Design recommendations

Many of our new designers have asked us for design guidelines. As such we are going to present here what one of our printer manufacturers reccomends. We are more than happy to work with you on developing or transferring an existing design. Please contact us if you would like us to review your design at info@3dptrain.com.

 

Minimum Supported Wall Thickness

A supported wall is one that is connected to other walls on at least two sides. Walls with a thickness less than 0.2 mm are prone to warping during the peel process. Test walls measured 25 mm x 25 mm.

Recommendation: 0.2 mm

 

Minimum Unsupported Wall Thickness

An unsupported wall is one that is connected to other walls on fewer than two sides. Walls with a thickness less than 0.2 mm may warp or detach from the model during printing. Test walls measured 25 mm x 25 mm.

Recommendation: 0.2 mm

 

Minimum Vertical Wire Diameter

A wire is a feature with a length that is more than twice its width. The length-to-width ratio is critical for printing wires. At 0.2 mm thickness, wires can be printed up to 7 mm tall before they start to exhibit waving. Wires with a thickness of 1.5 mm can reach up to 30 mm in height without defects.

Recommendation:

  • 0.2 mm (up to 7 mm tall)
  • 1.5 mm (up to 30 mm tall)

 

Minimum Embossed Detail

Embossed details are shallow, raised features on your model, such as text. Features smaller than 0.1 mm in thickness and height may not be visible in the final print.

Recommendation: 0.1 mm

 

Minimum Engraved Detail

Engraved details are recessed features on your model. Details with a recess less than 0.15 mm in thickness and height may not be visible, as they may blend with the rest of the model during printing.

Recommendation: 0.15 mm

 

Minimum Clearance

Clearance is the required distance between two moving parts of a model (e.g., gears or joints). A clearance of less than 0.5 mm can cause parts to fuse together.

Recommendation: 0.5 mm

 

Minimum Hole Diameter

Holes with a diameter less than 0.5 mm in the x, y, and z axes may close off during the printing process.

Recommendation: 0.5 mm

 

Minimum Drain Hole Diameter

Drain holes are necessary for resin to escape from models with fully enclosed cavities (like hollow spheres or cylinders printed directly on the build platform). Without drain holes of at least 2.5 mm in diameter, trapped resin may cause the print to fail or explode.

Recommendation: 2.5 mm diameter

Multi-Part Models

I have models that are one or more parts, How do you handle them?

Unlike other companies that treat each part as a seperate product, we do not. We have no issue printing multi-part models. We do not require them to be on a single sprue to be considered one model, truthfully they tend to print better as free-standing parts.

Just be sure to name the files as directed in "How do I add a Product" with each part having its own part number and qty in the name. To upload them to the site just put them in a zip file and upload them as described in Getting Started > add a product.

Multi-Option Models

Our software allows up to 3 option types with a large number of options each to fully customize your product or offer modular kits. We will be adding additional instructions on how to add these soon. Please contact us if you have questions on how to do this in the meantime.

Pricing

Thank you for considering our products! We recognize the importance of both price and quality in your decision-making process. We're thrilled to introduce you to our innovative 3D printing products and explain why our prices may differ from other companies.

 

Firstly, our premium products are proudly American-made! We manufacture them in Tennessee using resins manufactured in the United States. This eliminates international supply line issues, ensuring a more efficient and reliable delivery process.

 

A significant factor contributing to our product pricing is the premium resins we use in our manufacturing process. We have chosen resins that are formulated to be environmentally friendly, minimizing the negative impact on the environment, with a composition no harsher than normal household chemicals. In terms of quality, this resin delivers exceptional results—providing a smooth, matte finish that enhances aesthetic appeal and showcases intricate details without the need for primer.

 

Because we have prioritized safety from day one, our manufacturing process requires no specialized exhaust systems or post-production precautions, ensuring a safer working environment for our employees. This extends to our customers as no additional precautions are needed when handling, modifying or finishing our products.

 

While our prices may be higher, our dedication to environmental sustainability, superior quality, and safer manufacturing practices makes our 3D printed products a valuable investment. We're committed to delivering an outstanding experience and products that exceed your expectations.

Production Times

Our products are manufactured on a made-to-order basis, with the majority of orders requiring 7-14 business for production and shipping.

Certain large models necessitate a lead time of 4-6 weeks, owing to their considerable size and the extended printing period essential for their creation.

Although infrequent, instances of prolonged production timelines may occur due to heightened demand or unforeseen delays.

Finishing models

When you receive your items you may notice some small post-production markings on the products.

These are unavoidable in the production of the models. A small amount of work could be necessary to prepare the model for finishing.

  1. Once you get your model, locate any lingering supports/sprues, and remove them. This can be easily removed using a set of snips or break them using another tool.
  2. Using a sanding stick file any raised areas from the sprues.
  3. Next clean the items with Isopropyl alcohol (IPA) 90% or higher. You can spray or dunk the item in the IPA If there are difficult spots you can use a soft toothbrush and rinse with more IPA. Once the model is clean allow the item to fully dry. be careful not to soak them for more than a few minutes as the IPA can affect the printed model.
  4. If your model requires additional detail parts, please add them at this time. Any CA glue will work, but my favorate is Mitreapel Ca Glue with Activator. IPA will dissolve this type of glue. (Not all models require this step)
  5. Once your model is complete you can paint and decal as you desire. I would highly suggest using an airbrush.

Our Guarantee

We strive to produce merchandise of the highest quality. 3D printing is a relatively new manufacturing process and we are exploring the limits and boundaries of this technology. We aim to provide our customers with consistent quality; unfortunately, when exploring new technologies, there are times when this might not be the case. Due to the hands-on nature of the production and post-production; issues may arise. Please feel free to contact us with any issues or concerns.  We appreciate your continued patience when issues do occur going forward.
