Frequently Asked Questions

Below we have answered the most common questions we receive.


Materials, Colours & Finishing

We offer a range of 3D materials and have the expertise to print them to maximum effect. From rigid bio-plastics to flexible TPU to wood fills, you can make amazing 3D prints with us.

Here are a few examples:

  • rPLA (A strong rigid bioplastic, very good for prototyping and affordable).
  • PolyMAX PLA (20% stronger than ABS with great mechanical qualities)
  • NinjaFlex (Shore 85A) a very flexible rubber-like material.
  • Cheetah (Shore 95A) a flexible abrasive resistant rubber-like material.

Read more about our materials.

We offer a vast array of colours. When you upload 3D models using our uploader you will be able to view a swatch and select a colour per model, so you can order multiple parts in different colours/materials in a single order.

You can also view our gallery of 3D prints and see some of the colours we offer.

Matte Colours
We also offer matte colours which are greater at defusing the light that hits an object.

Translucent Colours & Materials
We also offer translucent colours which let light pass through.

Hand Painting, Effects & Finishing
We also offer painting and hand finishing of all 3D models you print with us, we can match any colour swatch, or effect you’re looking for, including gold leaf. This process of course, adds production time to any order and should be discussed with us first, contact us to talk about bespoke finishing and colours and to get a custom quote.

Made to Order Colours
We are able to order in custom colours from our supplier that match a RAL code.

  • Colour already matched by factory: 7 – 10 working days
  • Colour not yet matched by factory: approx. 3-4 weeks, depending on the colour matching process.

Please contact us well in advance if this is a service you require.

For very solid, rigid parts with tough mechanical properties, we recommend selectin PolyMAX

You can read all about our materials in more details here.

We offer translucent material. Please note that “transparent” will not necessarily be completely see-through, due to the infill structure built within a model and the nature of 3D printing but it will let light pass through, we offer translucent in a range of colours.

You can choose translucent when ordering online using our uploader tool or contact us if you have any more questions.

Yes! We are one of very few studios that specialise in 3D printing flexible material (TPU). We have the expertise and equipment. We offer NinjaFlex (Shore 85A) and Cheetah (Shore 95A).

You can read all about our materials in more details here.

You can determine the hardness of a material using the Shore hardness scale. We can also use 3D printing techniques to change the 3D print settings, such as the density of the infill structure, which can affect the flexibility of a model.

Shore hardness is defined as a material’s resistance to indentation. The higher the number, the greater the resistance (and therefore, the “tougher” the material). Shore hardness should be used with caution in 3D Printing. It is only accurate for parts with 100% infill density. We print most 3D parts with 25% infill density, therefore the flexibility of the part will be slightly different from what you would expect based solely on the Shore number.

Depending on the level of flexibility you require, we can change the infill percentage and other settings, contact us to discuss your project.

3D Modelling (CAD) & Digital Sculpting

We recommend using any CAD software you’re comfortable with for 3D modelling your parts for 3D printing or TinkerCAD if you’re just getting started with CAD 3D modelling. However we recommend learning about the importance of a watertight mesh when exporting your 3D model in STL or OBJ format from your chosen CAD software.

We use Autodesk Fusion 360 and ZBrush in-house, which are a great choice.

Make sure you combine all your bodies to form one solid body when exporting your as an STL, STEP or OBJ file.

Especially when exporting from Rhino, SketchUp and SolidWorks, there may be mesh defects.

Useful Guides for preparing your 3D model for 3D printing
You can read our export guides for different CAD software here.

Our printers can print without supports up to about 55-60 degrees then supports are required, they leave a gap of about 0.3mm between the model and the overhang surface. If you design your parts with this in mind you won’t need to use supports, which also lowers the material cost and the print time needed, and increases the surface finish of your model as support material will leave some post-processing to do.

Our largest print volume is 450mm (x) by 450mm (y) by 470mm (z).

If a model is larger than this, you will need to split it up into component parts that fit within our max build volume are and assemble it post 3D print.

Our max 3D printer volume is 450x450x470mm. We suggest you split it into component parts and attach them together post 3D print. Super glue works very well when joining 3D printed parts.

Yes, we offer both technical CAD 3D modelling and organic digital 3D sculpting, so if you have a drawing or concept that you’d like to turn into a 3D print, we can make it happen.

To get started, please fill in our short questionnaire and tell us about your project and someone will get back to you to proceed.

3D Print Settings

While every part is different, we use a grid infill of 30%. For very small parts, we would use 100% infill. in all cases our experienced technician will choose the appropriate density for your geometry.

If you have preferences, please just leave us a note when ordering.

We use a Rectilinear infill structure as default.

We normally print a wall/shell of 1.6mm. If you require something else, let us know when ordering.

Cost of 3D Printing

3D printing cost is based on a number of factors:

  • The scale of the object
  • The type of material chosen. Some materials cost more than others. Learn about the materials we offer here.
  • The material volume used in cm3
  • Lead time. Turnaround is typically 2-3 working days. We also offer Express 1-2 working days and Weekend service at an additional cost.

All prices are quoted instantly on a per model basis when you use our quote and order engine.

There are several ways to lower the 3D print cost:

  • Reduce the scale of your model if possible.
  • Avoid large overhangs (Greater than 45-65 degrees) where more support material is required. Support material is included as part of the overall material volume.
  • You can select a lower-cost material, for example Standard PLA as opposed to Polymax.

When you upload your model using our quote and order tool you will see the cost in real-time as you change materials and preferences per model.

No, it will only create support material within your model, increasing the 3D print time and overall material volume used.

Export your 3D model as a solid body, and our experienced technician will choose the appropriate density for your geometry.

Examples of different Infill percentages. We use 30% as standard as this works well for most models and creates a strong model but doesn’t waste material where it is not needed.

If you have a preference just let us know in the notes section when ordering.

Yes we do, after uploading your model using our quote and order tool you will see the bulk discount applied as you increase the quantity over 5.

We have a minimum startup cost.

This covers:

  • Geometry mesh analysis and preparation of models(s) for the 3D printer by a member of our team
  • Printer setup
  • Printer cleaning
  • Any test prints required to optimise model for 3D printing.
  • Post print material support removal (if applicable to a geometry).

We recommend, if possible printing more than a single item if the item is small in volume.

You can view this startup cost when uploading your 3D models via our order engine.

Time & Turnaround

Our typical turnaround is 2-3 working days. We also offer Express and Weekend 3D Printing services at an additional cost.

You can a lead time when getting a quote or placing an order with us using our quote tool.

As soon as you upload your 3D models, our system will analyse them for printability and once the order is paid it will enter production and you will be notified by email of the order progress. You will also be sent a tracking code once the order has been shipped out.

If it is not 3D-printable, we may ask you to fix the errors prior to proceeding with production.

We will work with you to resolve any mesh defects.

However, if the model is not fixable, we will cancel the order and issue a full refund.
