Pricing model

A print is priced by weight. One all in rupee rate per gram covers the filament and the normal machine time, billable weight rounds up to the whole gram, and there is no minimum per part. Prints for India are made in India by our print partner and delivered across India. This page gives you the whole calculation, so you can work out your own price before you upload anything.

The formula#

billable grams = ceil(grams)
per part       = billable grams x rate per gram x quality factor
order subtotal = per part x quantity x bulk factor
delivery       = ₹79, or free when the order subtotal is ₹999 or more
order total    = order subtotal + delivery + Priority print and support removal, if chosen

Everything else on this page is either where the grams come from or which number goes into which slot. Nothing is added for setup, file handling, supports or brim: supports and brim are plastic, so they arrive as grams and are paid for as grams. Taking the supports off afterwards is optional: support removal, ₹200 once per order if you choose it on /in/print.

Three charges sit outside the per gram part and only appear when they apply: the ₹500 second AMS fee for a print in 5 or more colours, below; Priority print, 10% of the items and never less than ₹200, once per order if you choose it, which prints the order in 1 to 2 business days instead of 1 to 3; and support removal, ₹200 once per order. Normal print is included. None of them is discounted or counted toward free delivery.

Rate per gram#

Density is part of the price, not a footnote. The same model in ABS weighs about 18% less than in PETG, so although ABS is ₹10/g against PETG's ₹8/g, it costs only a little more to print. See /in/docs/materials for what each plastic is actually good for.

Quality factor#

Premium halves the layer height, which roughly doubles the machine time for the same weight of plastic. The factor multiplies the per gram charge; it does not add an hourly line.

Where the grams come from#

Two sources, and the quote says which one it used. Measured always beats modelled.

• Measured: the file is sliced by OrcaSlicer on a real Bambu printer profile, and the filament volume it reports is converted to grams with the material's density. TPU is measured on a TPU profile; the other plastics on Bambu PLA Basic. This is what the quote uses wherever a slice can be run. It takes ten seconds to a minute, so the first number on the page may still be the estimate.
• Estimated: a geometric fallback used before a slice lands: model volume x (0.30 + 0.70 x infill), then x density. The 0.30 is the solid perimeter walls; infill fills the rest. Requested infill defaults to 20%.
• A plate you sliced yourself (a .3mf or .gcode.3mf plate export) is always measured: the grams and hours come out of the file's own header, and they already contain every purge, support and brim.
• A print in colour is always measured too: a project is sliced in its colours, and that slice's grams and hours are the price.

Rounding, and no minimum#

• Billable weight rounds UP to the whole gram, like postage. 39.92 g bills as 40 g.
• There is no minimum per part in India. A 3 g PLA keychain is 3 x ₹8 = ₹24, and ten of them are ₹216 after the 10% bulk break.

Worked example#

A part measuring 60 x 40 x 30 mm, PLA, Standard quality, 20% infill, one piece, delivered in India. Every step below is arithmetic you can repeat.

1. 1
   Start from volume

   An uploaded mesh gives its real volume. To keep the arithmetic short, this example uses the bounding box: 60 x 40 x 30 mm = 72,000 mm³ = 72 cm³.

   textCopy

   60 x 40 x 30 / 1000 = 72 cm3

2. 2
   Apply walls and infill

   30% of the volume is solid wall; the remaining 70% is filled to the requested infill.

   textCopy

   72 x (0.30 + 0.70 x 0.20) = 31.68 cm3

3. 3
   Convert to weight

   Multiply by the density of PLA, 1.26 g/cm³.

   textCopy

   31.68 x 1.26 = 39.92 g

4. 4
   Round up

   Billable weight is a whole number of grams.

   textCopy

   ceil(39.92) = 40 g

5. 5
   Apply the rate and the quality factor

   PLA is ₹8/g and Standard quality is 1.00.

   textCopy

   40 x ₹8 x 1.00 = ₹320 per part

6. 6
   Multiply by quantity, then add delivery

   One piece gets no bulk discount, and delivery is ₹79 because the order is under ₹999.

   textCopy

   ₹320 x 1 x 1.00 = ₹320
   ₹320 + ₹79 = ₹399

A box is an upper bound: a real model inside that box weighs less. Upload the file at /in/print for a quote from the model itself, or work from a weight you already know at /in/3d-printing-cost.

Quantity and bulk#

Multi colour#

A print in colour is priced from a real slice of it in those colours, never from an estimate. There are two ways to get one: a plate you sliced yourself, priced from its own header, and a Bambu Studio or OrcaSlicer project, which we slice plate by plate in its own colours. In both cases the purge and the filament change time are already inside the measured grams and hours, so nothing is added on top for them. Charging them twice would be an overcharge.

What colour does change is the rate per gram: +₹0.6/g at two colours and +₹0.4/g for each colour after (PLA ₹8.6, ₹9 and ₹9.4 for two, three and four). The same steps apply to every material that prints in colour (ASA is ₹10.6/g at two colours), and the quality factor multiplies the whole rate. A colour print spends hours swapping and purging that a one colour print of the same weight does not, so 100 g of PLA is ₹800 in one colour and ₹900 in three.

Colours are counted by what prints. A filament the file assigns but the slicer never feeds is not counted and not charged for. Up to eight colours print, which is two AMS units. On a plate you sliced yourself, measured hours far beyond what its weight implies, which is filament change time, are charged at ₹30 an hour.

A colour project is priced at 100% scale and standard quality, at the rate of the base plastic its own filaments name (a plate in PLA-CF is priced as PLA), because that is what its slice measured; those controls are locked on /in/print while colour is chosen. See /in/docs/studio/multi-color for how colours are checked.

Delivery#

Delivery is charged once per order, not per part. Normal print is printed in 1 to 3 business days, then delivered in 3 to 7 days. Priority print (₹200, or 10% of the items when that is more) is printed in 1 to 2 business days, then delivered in the same 3 to 7 days. There is one delivery service: no express, no international delivery and no pickup.
