Feature Update: Hub Pricing

Bram · 2015-10-21T08:21:13.000Z

Hey @Flabou2! In order to do this you can use the Object volume. It should correspond linearly with the weight. You can check the density of your material with your supplier. Currently our catalog of materials doesn’t contain accurate information on these densities. As soon as it does we can start to supply this information for you.

Cheers!

Hey @meagan_mason_75, what factors would you need to have taken into account? Currently you are already able to take the amount of volume and amount of prints (first print, subsequent prints) into account for pricing. I understand these are only rough indicators of printing time but nonetheless helpful. Any suggestions for this would be taken into account, cheers!

Good morning there! How would I go about demoing these new features? I took a peek at the hub options and I don’t appear to have any new pricing options on my dropdown lists for filaments. I also don’t have any new orders currently to take a look at potential changes to the volumetric pricing.

Press_Fab · 2015-10-21T17:20:05.000Z

i would like to see time, hours or minutes taken into account as a pricing strategy. i.e. large, tall prints take longer than prints that a large on the x and y but not the z.

so either a height surcharge beyond a certain point, an option to price by time, so X currency per hour / minute etc, or some effort made to educate customers that some types of prints will be expensive because of the time it takes to make them rather than the material cost which might be small.

I have just read all the thread and totally agree with lyratron and TypeR, and the guys in the end talking about considering the time required to print an order with FDM printers. (I am sorry guys, this will be a long comment.)

For 3DHubs, up to now, I have considered start-up price to be equivalent to 1 hour printing and the $/ cm3 to be $ / 1 gram weight of material to be used. This is to say I neglected the cm3 dimension and replace it with gram. I need not to know the density of the material. All I know is how much does it costs me per Kg or g. Suppliers do not provide density information.

In the end of September I commented on this issue to the support person asigned to me:

"…1. 3D Hubs quotes on a startup price per job. On the other hand, I cannot charge per job since I estimate a price per hour-machine (this is the number of minutes the printer will take to print the order) plus material used for the printout plus delivery conditions.

I am considering the startup price to be equivalent to one hour printing, then I add up to the price the fee related to the extra-time needed to finish the print. This is the startup fee times the number of hours (or minutes) required to print the object.

"…4. Also in 3D Hubs base quotaton, volumen of the object is considered. But, softwares like Cura, provide an accurate amount in grams of the material to be used. "

(If not accurate at least it gives a very good approximation. I have compared several times by weighing the printout.)

Popular slicers like Cura provide estimated information on time and amount of material to be used, this allows to easily estimate a price. I think estimating the price per job is very inconvenient since it does not consider the time required to complete the job. And, on the other hand, estimating the material cost per volume may give a good aproximation when you do not have slicer sofware at hand or when you are on the street and people ask you for a price. But if you have slicers that provide time and weight info, then why not to take adavantage of that?

In my opinion, Hubs (or Hubbers ?) should be free to fill out a simple form depending on the type of printer they use FDM, SLS, etc. In the CNC industry they charge for the time required to machine a piece. It should be the same with 3D printing. No need also for different quote for high quality printings since high quality printing always take much more (?) time to print. As a result, a high quality printing will be always more expensive. The same as with large printings.

About considering weight or volume for material cost, I think both options should be considered in the form. Not just volume. It will be hubber’s(?) decision to choose the method that better suits him/her.

Additional costs is another issue to talk about.

Make it simple.

Hi Filemon,

Thanks for making the recent changes to the ordering system and giving back the ability to enter sliced object volumes. I see some other great suggestions in this thread (especially the volume/time/mass options), but I’ve received my first order since the fixes and it’s workable for me now

Thanks again

Your giving the customers to much room to screw up with these settings. I have dealt with many that think I print out of thin air and have prices that cheep. Going by cm3 was cumbersome but worked for FDM printing (I figured it from the density of the filament). Now trying to sell by bound volume and surface area is just asking for trouble. Especially when customers don’t understand bridging, brims, and supports. That add more cost to the print. I’ve had all my files come in needing some extra material that the customer did not factor in.

If you want to make some changes, make mass the way to price a print. We buy and use filament by the kg / g, we can check it quickly on a scale for the final amount used, and shipping is calculated by mass. This will help us correctly price our print, because I’m shortchanged when you take orders by volume. Your program underestimates the volume of a print consistently, especially when we don’t have all the parameters needed to gauge the true size (shell thickness, infill, etc…)

If I have a choice I’m sticking with cm3 for pricing.

Also I’d like to be paid by time. I’m doing an order now that will take 2-3 weeks. That is a lot of time to tie up my one printer, and I’ll have problems if someone else places an order. Even though the customer pays for the material, that is nothing compared to labor cost.

Cheers @wei_sheng_3139, happy to hear that

StephanG · 2015-10-23T13:51:25.000Z

Great new update with the 3 different Marvin sizes!

Rifle · 2015-10-23T15:18:58.000Z

Can you add an “infiltration” or “sealant” option to the additional fee portion.

That would greatly help us using powder based 3D printers.

I don’t use support material, but I do seal the parts after print and there is a definite cost to this.

The best way to estimate this cost would be a factor times the surface area.

thanks,

Rifle Creek

Hey! you should already be able to select surface as one of the components to base your pricing on!

Bram · 2015-10-26T14:04:27.000Z

Hey! Time to print really differs from technology to technology. I do recognise that time to print and labour would be great components to base your price on. Will take this into account!

Mitch_1 · 2015-11-11T06:59:23.000Z

so what happened to adding additional costs for more than %20 infill, and if support is needed as with most standard extruder type 3D printers? also I dont see my material costs per c3 anymore, what happened to that?

obelix · 2015-11-11T11:32:59.000Z

Hello @Filemon

how can a delete a printer?

Filemon · 2015-11-11T16:41:18.000Z

Jep, that’s a bug :s

Currently you can only put your printers offline. Fix will be deployed late this week or somewhere next. Sorry for that

FabCreator · 2015-12-23T00:23:50.000Z

Does anyone else find judging the cost of the material buy the size of the 3d hubs guy really confusing? is it possible to make it an option of how to show the price. per cm/3 instead of this new system? which with all the options can get really hard to compare.

Cheers,

Bonne

Dane · 2015-12-23T00:26:40.000Z

I’m also very confused by why pricimg is now done according to sliced volume rather than object volume. Its way less transparent this way which is a bit disappointing…

FabCreator · 2015-12-23T00:31:08.000Z

I think it was always Sliced volume?

My issue is how can anyone possible compare the prices of the different materials and layer heights and everything else when we have a bizarre system of Marvins. i have not paid much attention to the update till now as i have been busy.

MicroVentures · 2016-01-14T03:24:01.000Z

Please allow us to add a NVPro printer by NVBots (http://nvbots.com/nvpro/). Thanks!

Josh_Raples · 2016-01-14T04:35:30.000Z

Way to bring back a dead thread… On a side not though, did you actually buy one of those? Last I talked to the owner he said the price tag was $15k
