General 3D Printing Questions

Q: Could you 3D print guns and sword?

A: We can only print props for you, anything restricted under Singapore Arms and Explosives Act (Cap. 13) and the Arms Offences Act (Cap. 14), we can’t help you to 3D print.

You can check out the document here.

If you have question on the refund please visit FAQ Payment

Q: Why can't I see the cost instantly?

A: Usually you should see the cost instantly after system anylise the 3D file. If you don’t see the cost instantly there maybe some major error in your file that the system couldn’t precoess it:

1) Multi intersecting objects in the model.
Please merge all parts together and export a single solid object (watertight) in the format of STL or OBJ.

2) Non-manifold object.
Check and fix the model manual make sure it is a printable 3D model.

Here are some articles on the non-manifold:

3) Thin wall on part
Check out the minimum wall thickness for the printing method you’ve chosen.

4) Part size to tiny or too huge
Export your file in the unit of millimeter (mm), part/object size bigger than the printer build size will be resized by the system automatically to fit in the build size, please check the Model Dimensions shown at the information table.

Q: What if I need assistance on checking my parts printability and estimated printing time?

A: We can help checking your parts printability, but we don’t check your design. You are the one familiar with the part design, please check carefully before uploading.

1) You have to upload your 3D STL or OBJ file(s) and place order. Yes, have to place order else we can’t downoad your files.

2) During check out page select the option “Please check file printability”. You won’t be charged yet until we check the part(s).

3) Text us on the input field if you need to know the estimation printing time.

4) You will received system notification to proceed payment if they are printable. The order will be cancelled if the part(s) are unprintable.

5) Proceed payment and we can start process your order.

Q: Can you help me to fix the error on the model?

A: We suggest to upload your stl file to Netfabb Online Service to fixed the posibily error, it’s free. Download and double check the fixed file, to make sure it is fixed correctly before uploading to our website.

If we notice any part is having error, we will try fixing the model with Netfabb Online Service. Anything can’t be fixed by Netfabb, we will contact you to fix send the amended file(s) to us.

We may need you to top up the cost difference of amended model.

Q: Why I can't upload STP or STRP file?

A: We have disabled STP or STEP from the uploading format.

The system is best processing STL or OBJ format, very often the STP files included unwanted parts or unprintable 3D object.

Q: Can you give a estimated printing lead time? Can I get the order wihtin the estimated lead time?

A: Please be understand that it is an estimated lead time, the printing process may be slightly shorter or longer, if you have multiple parts, the part is intricate or the part is big in size, it may take longer.

Do note that if your order is printing with FDM machine, it may take time and there maybe risk of fail print if the part is having intricate design. We may still need to carefully remove the support material from the printed parts.

We will print the part with minimum risk based on our experience, but low risk doesn’t mean no risk. It’ll be great to plan your project with longer time for 3D printing process. We apreaciate for you understanding and patience.

PLA (FDM)

Things to note for 3D printable model:

1) Export your files in mm (millimeter), in the actual print size you want it to be.

2) Suggested file format are .stl or .obj

3) Merge/boolean/union all intersecting objects into a single solid (watertight) object, make sure no intersecting objects, no broken polygon, no extra unwanted spline or edge.

4) All objects must have thickness, plan with one face are not printable in the real world.

5) Make sure there is no inverted normals, outside faces should always facing outward.

6) Suggested minimum wall thickness for FDM printing is 1.2mm. Minimum thickness 0.8 to 1.2mm (depending on the design)

7) Multiple parts please upload individually and select colour accordingly.

8) Upload your stl file to Netfabb Online Service to fixed the posibily error, it’s free. Download and check the fixed file, to make sure it is fixed correctly before uploading to our website.

 

Q: What is infill?

A: FDM Printing usually don’t print an object solid, instead we just printing in certain percentage of infill. This is to cut down printing time and cost. The higher percentage the infill is, the more solid the printed object is. Beside the solidness, infill also act as a support for the roof of the object, in some cases, printing without infill may causing the top of the part collapse. 20% is the most common setting to be used, it printed in shoter time and given a relatively sufficient support to the object top / roof.

Q: What is layer height?

A: The layer height define the thickness of each layer, 3D printing process deposit material layer by layer to form an object. The smaller the number of the layer height, the thinner the layer is, thinner layer heigh create smoother surface, just to take note it will increase the printing time significantly as well. For normal usage prototyping, 200 micron is good enough.

Just to take note, 200 or 100 micron layer height doesn’t mean it can print even thinner detail. The extrusion is determined by the nozzle size, which is a standard 0.4mm installed on all our 3D printers.

Q: When can I get my order if I place order now?

A: It depend on the size of your part(s), beside that number of parts and intricacy will also affect the processing time. 3D printing take times, it will be great to allocate sufficient time for the process, in case of fail print, it may take more time to reprint.

For shipping related question please visit FAQ Shipping.

Q: What is the printer build size?

A: We are using printers with build size 22 x 22 x 25cm and 30 x 30 x 40cm, and one 50 x50 x 50cm. We don’t suggest to use up the maximum size when preparing file. It’ll be great the part is 1 or 2 cm smaller than the build size.

Q: Can I have specific printing orientation for particular model?

A: If you have specific orientation of your 3D model to be printed, please change the position accordingly, at the left we will have a check for you.

If it’s not set we will decide the best orientation for your 3D moded.

Left panel below the perview canvas.

Q: Will you remove the support material for me?

A: Yes, in most cases we will remove the support material for customers. Only when some circumstanses below we may unable to help remove the support:

1) The part is thin and the support is a lot.

2) The support are in the cavity.

3) Part is too intricate.

Hope you can understand, we really don’t wish to break the parts during the process of removing the support.

Q: Why are some area of my part rougher than the rest of surface?

A: The rough surface could be the overhang area. Overhang area will need support underneath so that the molten plastic can still form the desire shape. There is an empty layer in between support and the actual object, so the support can be removed easily when the part printed, it’s technically printing in the air on those overhang area, this is why those area can’t print proper like the rest of the area and become rougher.

We don’t use water soluble material for support, as most of our 3D printers are single extruder. Using water soluble material will incur extra meterial cost and printing time.

Q: Why my printed parts can't fit or put together?

A: If the parts are mean to be fit together, make sure there are alloance given, we suggest 0.2mm for the allowance.

Upto 90% of the orders, we have no idea what are they for. Kinldy check your part properly before uploading, we can only check the printability, we ara unable to check on the design.

Resin (SLA) and Nylon (SLS)

Things to note when design part for Resin and Nylon printing

1) Export your files in mm (millimeter), in the actual print size you want it to be.

2) Suggested file format are .stl or .obj

3) Merge/boolean/union all intersecting objects into a single solid (watertight) object, make sure no intersecting objects, no broken polygon, no extra unwanted spline or edge.

4) Minumum wall thickness Resin (SLA)

White Resin: Minimum 0.5 mm

Transparent Resin: Minimum 1 mm

5) Minumum wall thickness Resin (SLA)

Minimum 0.8 mm

Please note that a bove suggested minimum thickness could be vary from different design, longer area should be made thicker than the suggested minimum thickness.

Q: Why it take so long to print with Resin and Nylon?

A: We work with our partner to provide the Resin and Nylon prinitng, parts will be printed oversea and ship back here, therefore will take longer on the process.

Q: Can you help me to polish the printed part?

A: We only focusing on the 3D printing services, con’t handle the post process services, therefore we can’t help sanding or polish your printed part.

Q: Can you help me to paint my part?

A: We can’t help painting your part as we only focusing on 3D printing services at the moment, we will provide painting service when we have more man power.
